Computer Cores

[exotic prairie]

Does the ST core support DV? As soon as I load it, my tink is like “nah, no signal here dog”. It’s the only core that does that. Core works fine on my non dv displays

It’s weird because usually, if I load up a non dv core, the picture is just messed up

I don’t know if I have ever seen no signal while the mister is on (and it is on because I can still reboot it from the invisible osd)

I could test it but it’s downstairs I’m upstairs and it’s 6:30am

[fleet cave]

hmm, it had sys framework updated last year, so I think it should be up to date with DV stuff

[exotic prairie]

Wonder if it's a weird resolution thing

[lunar trellis]

Was it not in a similar boat to 486? Maybe @chilly rain knows more, he did a lot of testing on these

[chilly rain]

you have to use vga_scaler=1 in the ini for that core

it doesn't really support direct video

well ao486 doesn't anyways

i just saw you said ST nvm

yeah sorg updated it, i feel like it should work, but you might need vga scaler for it as well, i'm not sure about the ST in general

i have never fired up the ST core more than maybe once or twice hehe

[exotic prairie]

Yeah, it works on all the other displays, so I will try that. That sounds like it could definitely be the issue - I'll try disabling DV first and go from there

[fleet cave]

he's probably just trying to watch all those nudie demos

[chilly rain]

i can't remember what system that was that had the nudie demo

one of those former soviet bloc computers

i'll leave it up to you all to find it

i found it once and couldn't stop laughing

[exotic prairie]

(͡° ͜ʖ ͡°)

[frosty cosmos]

You mean Atari ST? Yes, it works fine with direct video here.

[exotic prairie]

Might be the image I’m using

@frosty cosmos anything special in your ini?

[frosty cosmos]

Not really. I'm using TOS 2.06 and a VHD i found in an archive.org archive called 1000gamesT02.vhd

[elder cove]

In keeping with the Middle Earth theme, Beam Software's 1983 text adventure The Hobbit is going up now:

This one's a new kind of 0MHz config built directly off a floppy image, as certain games are small enough to fit both their install and a MS-DOS boot setup on a single 1.44 MB floppy. You'll see that more when I get into the ZZT packs.

[hazy tree]

Can you make them play floppy disk access sounds? 😸

Couldn’t wait to get to hard disks and cds at the time, but man I miss loading stuff from floppy disks

[lunar trellis]

Oh nice, I forgot there was a Hobbit text game, I think I may have played that on something else way back when like BBC Micro

[lunar trellis]

Ah, yeah it was on a few things including BBC and ZX

Interesting nugget:

the game might be regarded as one of the first examples of emergent gameplay. This also resulted, however, in many bugs; for example, during development Megler found that the animal NPCs killed each other before the player arrived. The game's documentation warned that "Due to the immense size and complexity of this game it is impossible to guarantee that it will ever be completely error-free". Melbourne House issued a version 1.1 with some fixes, but with another bug that resulted in the game being unwinnable, forcing it to release version 1.2, and the company never fixed all bugs.[5]

[strong yoke]

Speccy perhaps? If you remember it drawing the pictures out one vector at a time, it probably was https://www.youtube.com/watch?v=AB6HFwjwFAM

[lunar trellis]

Do you know what version of the game this is @elder cove ?

[elder cove]

I don't, unfortunately. However, I suspect the multiple release revisions are specifically for the Spectrum version, as it was first released about a year before the other versions were ported. (I haven’t been able to find any documented revisions on the DOS version so far, if they did exist, but I did manage to find earlier editions for the Spectrum.)

[elder cove]

Working on something really cool to show later tonight, but it's requiring me to compile some things in x86 assembly. Will update with that soon.

[exotic prairie]

Elphive is in the lab again

[copper slate]

What the heck is “Dooooh-EFFFFh ram” in the ao486 core used for?

[hollow ice]

That’s the ram that Homer uses when he messes up

[elder cove]

TetrOS, and Other Boot Sector Games is going up:

This is a wild one, and requires a bit of explanation. This collection is a 25-game pack of titles which run entirely within the 512 byte boot sector of a IBM PC boot disk. That's about 1/8 the size of an Atari 2600 cartridge.

All but one of these were coded entirely in x86 assembly, with the majority of titles being directly assembled from the original .ASM source code for this release.

[young gust]

You're doing amazing things @elder cove

Thank you

[copper slate]

@elder cove

[exotic prairie]

AtariST core is calling the police

[young gust]

QUICK UNPLUG IT!!!! 😂

[young gust]

Tried Star Trek 25th Anniversary (MT-32) and there's a ton of random audio crackling. If anyone gets a chance try it and see if you have a similar issue

[elder cove]

I didn’t encounter it with the opening dialogue, but granted I didn’t test very far (off-hand, I don’t know the controls).

[thick pendant]

I think the IO region for MISTERFS

[elfin oxide]

It might be the HDMI to VGA adaptor DAC as i have the same issue on one adaptor but not another

[exotic prairie]

This is Mister > Tink4k > TV, so I dunno what is going on. i just need to delete the core and see if that fixes it. Works fine under the same situation for @frosty cosmos

[lunar trellis]

@exotic prairie heard back from Jason on the X1:

It will support the standard tape formats found on the various archives, as this will be an official implementation that the X1 accepts.

[young gust]

Does anyone here use the various scan line settings to try to mimic the look of PC CRT Monitors? If so, share your settings! Ive been messing around with it with fairly decent results but would love to see what others have come up with

[frosty cosmos]

Have you deleted the Atari ST config files too?

[exotic prairie]

I actually didn't have any (I just moved the one over from a mister I know it's working on) - haven't retried it yet

[exotic prairie]

Redownloading the core and swapping to a known good config fixed it ¯_(ツ)_/¯

[opal phoenix]

Is there a way in amigavision to browse all games?

[exotic prairie]

I think you can do it by letter? I am not sure there is a single contiguous list though.

[frosty cosmos]

Too many games anyway. Doesn't make sense to have a full contiguous list. Not at that Amiga resolution.

[opal phoenix]

I though the list would just move on to the next letter once it reached the end, but had to go back and select the next letter. Kinda clunky.

[frosty cosmos]

There's the "go back" button on the pad (Button B e.g. on my M30 = CD32 pad button blue), nothing clunky at all. At least for me.

[robust monolith]

Probably Rob Northern or FAST if you know your ST. 🙂

[exotic prairie]

https://tenor.com/sudcJBoFVmJ.gif

[elder cove]

Anyone know of a good way to play an audio track on boot from a .MGL? This could be within the ao486 core or as part of the MiSTer, as long as it doesn’t cause significant issues with slowdown while running programs.

[copper slate]

I use this - https://github.com/wizzomafizzo/MiSTer_BGM

I set all the computer cores to play a little boot up fan plus disk drive access sound lol

[elder cove]

Eastern Mind: The Lost Souls of Tong-Nou is going up:

[spring lodge]

Please tell me, on the x68000 core in casting, if you go to the sound menu on the screen, there are artifacts, the question is whether the game is completely passable?

[elfin oxide]

One of my DV dacs will not show an image from the ST core going direct to CRT

[exotic prairie]

There is something funky about that core. Once I swapped to a working config and redownloaded the core, it started showing up fine - just weird

[elfin oxide]

Yeah i usually only boot it up to amuse myself. I really dont like AY music at all either

I keep meaning to swap my dual SDram Retrocastle build back to analogue as its handy to have both outputs.

[exotic prairie]

Ahh yeah, especially if you’re going to a crt

[void belfry]

I might have found the very first Linux LIVE CD distro running on ao486 and it's quite a rare/peculiar one:
https://distrowatch.com/table.php?distribution=tumix --- A Slackware (kernel 2.6.10) based distro made in **Peru **but the only version I found is the Japanese one
It fully boots on ao486, albeit slow (20-30 mins) because KDE and unused stuff etc. Can't much do anything really though, seems to throw a lot of errors when trying to run programs.
Will see if I can get it installed on a VHD (probably under Qemu and A LOT of google translate) and get it into a more usable form (thinking CLI, as KDE is way too much for the core)

[opal phoenix]

Seems they are no longer around

https://es.m.wikipedia.org/wiki/TumiX

The links are no longer working

[void belfry]

I started to browse distrowatch for country based ones to have a looksie to what ao486 might run. It was pure "why the heck not" moment when I decided to test it directly on the core rather than in emulator. An oh well... think I hit jackpot lol

[void belfry]

yeah, those are long time dead ones. here's the one I found : https://archiveos.org/tumix/

as I mentioned (see also in sshots), KDE is not fully working (or I lost patience at some time) but yeah, not any other Linux LIVE CD isos I tried were usualy compiled with SMP or no Math emu

[opal phoenix]

Odd a Peruvian developed distro is in Japanese. Even more so 20 years ago.

[void belfry]

that was... literally cherry on top

I so much want to get my hands on a Peruvian one, can handle spanish to much more extent without going to google translate images 😄

speaking of Peru, ~~another ~~ the other one would be Condorux

unfortunately didn't find any isos yet (not sure it would work though, didn't had any luck with Knoppix in general on ao486)

[opal phoenix]

I did found out tumix developers names. Will see if they have any contact info.

[void belfry]

Campaign seemed to be stopped/blocked (for now) as far as I can tell. I didn't get any feedback from IA team yet, but I don't see any more fake/malware posts (not only related to 0MHz but in general as well).

[void belfry]

Three more distros on test to see if I can recompile with math emulation (a Mongolian one and two Romanian ones)
https://distrowatch.com/table.php?distribution=soyombo
https://distrowatch.com/table.php?distribution=roslims
https://distrowatch.com/table.php?distribution=kiwi

being Debian based, should be doable in theory

[robust monolith]

It's just a hunch, don't know why, but @void belfry you do seem to like trying unix on the 486 core. Just a guess. 🙂 Good stuff though.

[deft estuary]

Hi there! Just tried Civilization 1 Mt-32 version from official 0Mhz Pack but it sounds very... poor to me on My Pi32 if I compare it with Dosbox or original Roland 32 video on YT:

[lunar trellis]

Hmm, anyone confirm it plays better from the Top 300 pack? Maybe something gone wrong somewhere

[deft estuary]

I cant’find it in top 300

[lunar trellis]

Oh interesting, I assumed it was in there

[deft estuary]

Ok guys got interesting findings about Civ 1 and Roland 32

First, ok my Mt-32pi setup was wrong and I’ve corrected it BUT

I’ve used an Exodos derived version (see next Pic for the exact version number) that sounds EXACTLY like YouTube videos and above all it has the same speed

I mean speed because in the Exodos and YT versions the intro is 1.22 minutes vs 3 minutes and beyond of official 0mhz pack, see (and hear) the respective videos below, first the Exodos

The slower last one is from official 0mhz official pack

Ok mistery solved. 0mhz official pack uses the slower version 475.01, Exodos uses the faster version 474.03, I don’t know why the older version seems sounds and show better

[elder cove]

Yep - I was going to say, I think in MIDI mode, looking at the display, which means it’s playing the audio using the FluidSynth virtual MIDI synth via a soundfont rather than Munt MT-32 LA synthesis.

(In future, you can tell on the display because it shows the MT32’s 1 2 3 4 5 R vol: 100 readout from the original system’s LCD. In the MIDI mode, it will just show 16 bars.)

[deft estuary]

Sure it was my fault BUT strangely the two versions have different sound and speed on MiSTer (with Mt32-Pi correctly set for Roland)

[elder cove]

Hmm - for some reason, loading it from the AUTOEXEC.BAT script is causing it to run slow. If I load the game directly from the .EXE via the command prompt, it loads like how you show the ExoDOS version running.

I’ll have to look into how the ExoDOS team has loading the game implemented.

[deft estuary]

ah ok thanks for the precious info!!!

[void belfry]

gonna take a bit, but still, the doubled PPP speed (230400 baud) rulz

[elder cove]

What does SET DIRCMD=/4 do under a DOS 6.22 environment?

[exotic prairie]

X1 updates - getting closer... https://misterfpga.org/viewtopic.php?p=97352#p97352

[void belfry]

for displaying in 4 columns iirc, you can ignore it

[elder cove]

MILO is up:

This one was requested on the SkyTrip America upload - quite an obscure game. I did my best to do some research into the title's history, but I unfortunately didn't come up with too much about it.

[young gust]

If you get a chance, some great windows 3.1 games that are unique and obscure, are The Dark Eye, and Millennium Auction, and Iron Helix.

[robust monolith]

There was, Solitaire. 🙂

[elder cove]

https://tenor.com/view/solitaire-solitaire-ending-solitaire-end-ending-bounce-gif-12792838

[elder cove]

Funny thing about that - The Dark Eye is going up:

[young gust]

HAHA

that's awesome.

it's a really unique little game.

As is Millennium Auction

Millennium Auction is right up your alley of cool, unique, and wacky Windows 3.1 games.

[elder cove]

Looking forward to trying it!

In general, I think the multimedia CD era (1993-1997) is one of the most underexplored in modern gaming circles. There are some real hidden gems there.

[young gust]

There is definitely a lot of unique stuff

If you ever do another April fools of bad games add Maabus (I think that's how it's spelled)

[elder cove]

Oh, trust me - I think I'm going to have another bad games pack before next April. For instance, I'm already working on a pack for this one:

I've seen Ross's Game Dungeon's video on Maabus, but I haven't tried it myself. Looks wild, though.

[elder cove]

That's actually part of a franchise called Blupi, interestingly enough. There's like 12 of them, all released as freeware over the years with several going open source - there's even a work in progress decomp for Speedy Eggbert.

[granite umbra]

But it is too slow on AO486

[elder cove]

I’m wondering if we want to start installing Q87 as default in Win9x for 0MHz configs. From what I’ve been testing so far, it brings a substantial performance boost.

[young gust]

What is Q87? I've never heard of it

[elder cove]

It’s a FPU emulator

[young gust]

Ah

[elder cove]

Basically emulates a math coprocessor that was an optional component - otherwise, software programs tend to use their own slower implementations of those math functions.

[copper slate]

If there aren’t any downsides then hell yeah

[void belfry]

It won't do any good/work under Win9x iirc. Q87 is just for DOS and needs EMM386/QEMM to function

[elder cove]

No, there's a Win9x virtual device driver for Q87, Q87.vxd. I've got a Windows 95 config with it running inside it, and it gives a decent speedup.

[void belfry]

ah ok, didn't try that one

sounds intriguing, will have a look at it tomorrow

[sweet scarab]

I have two 'sanity check' Amiga questions for those more familiar than I. First, AmigaVision replaced 'MegaAGS' rendering it obsolete correct? Second, each AmigaVision release should contain everything in previous releases rendering those earlier versions obsolete, correct? I'm trying to cleanup my NAS and remove redundancies.

[elder cove]

Yep

[young gust]

Now I gotta go see what is the latest AmigiaVision release to make sure I'm up to date!

[exotic prairie]

October of last year

10th maybe?

[young gust]

Ah ok, i should be up to date then

[elder cove]

I’d be curious about everyone’s opinion on this - I have a game which is intended to run at 640x480 full screen under Windows 3.1, but has a menu bar at the top - meaning that if you play in 640x480 mode, the top edge is cut off (and it looks awkward in that format, though it loses no essential video information).

Should I make the pack in 640x480, and lose the top part of the game’s window, or should I run it in 800x600, adding some black bars but including the whole image?

[karmic fog]

could you show us what those look like?

[young gust]

I'd go 800X600 so long as performance isn't compromised

[sweet scarab]

I agree, I'd rather see all of the intended screen, useful or not.

[elder cove]

Performance is the same betweeen modes. Here’s what it looks like, in comparison:

[bitter yoke]

I remember this game but it was the snow mountain version, whatever it's called

Treasure math storm

I'd go with 800x600 if it runs just the same performance wise

[young gust]

I'd definitely go 800x600

[karmic fog]

hmm, i like being able to see the whole image too but based on these images it looks like the game was intended by the developers to be played at 640x480... are there other versions of this game, like on DOS or other platforms where the art displays fully? or any way to hide the toolbar?

[elder cove]

I didn’t see an option to hide the toolbar, unfortunately. There is a DOS version, but with significantly worse visuals & audio (the original is EGA, and everything has been redrawn for this version.)

I suspect it was originally designed for Macintosh, where you can have the top menu bar disappear on mouse over. I still haven’t quite gotten a 0MHz ShapeShifter config set up yet, though.

[karmic fog]

makes sense

would be curious to see how the Mac version looks

[grim lodge]

Just get a slightly bigger monitor and the 800x600 will make up the size difference

[thick pendant]

@void belfry have you ever tried any unix like OS on Minimig core?

[void belfry]

tried Minix and NetBSD i think at some point, none worked (BSD think because MMU ?)

[void belfry]

atm researching to install Minix on X68000, found some archived JP sites with info to install it on a SASI HDD, will see

[void belfry]

@thick pendant even Linux lol

[thick pendant]

its always 8000000B

think that means nu FPU

[void belfry]

well, that would explain it

Don't really remember what was the Minix issue though, might retry it some time

[void belfry]

oh boy, Unix on 68000 is quite a rabbit's hole

[elder cove]

Odd question, but does anyone have a preconfigured FreeDOS or commandline DOS 7 installation for ao486?

I’ve got a DOS game with a hard drive install that’s too big to run in an original DOS partition, as it’s designed with DOSBox in mind. (Would need a drive around 1.5GB.)

[young gust]

When I made my vhd for DOS 6.22 I was able to have 2 gig in total for C drive

At least I think I did 😂 I'm so sick right now n tired I can't think for shit

[vestal ginkgo]

This is freedos based full VHD: https://github.com/flynnsbit/DOS_Shareware_MyMenu/releases/tag/v0.1.20.6 and there are a few updates: follow the instructions here: https://github.com/flynnsbit/DOS_Shareware_MyMenu?tab=readme-ov-file#dos_shareware_mymenu

can't remember how big I made the VHD but it is bigger than 1.5

It's 2GB, just delete all my stuff in the GAMES folder

[burnt pelican]

The only thing I can think of is if you have an existing 95/98 install, there's a bootdisk.sys which is a 1.44MB disk image in the windows directory that you can use to create a basic DOS install (e.g. an earlier version of winimage or dd or similar)

[void belfry]

Minix 2.0.2 running on AtariST core

Image is here : https://atari.joska.no/minix/, rename it to VHD and boot it. There are two images (minix202.img and minix204.img), rename one of it to "minix.img" then start minix.prg. Use root or minix as user, same pass Geheim

Unfortunately, it doesn't know PPP, only SLIP (and I'm not in the mood to redo all the work to get SLIP on MiSTer)

Meanwhile, anyone tried this https://github.com/oerg866/win98-quickinstall ? Just found out about it watching This Week in Retro 🙂

[robust monolith]

Coming up next @void belfry gets unix running on the zx80 core written in Forth. 🙂

[void belfry]

MacMinix running on the MacPlus core (https://www.pliner.com/macminix/)

I used @karmic fog VHD, just copied over the .hqx file, unpack it and runs like a charm

[void belfry]

Unix micro-kernel OSes like Uzix and Fuzix do run on Z80 based systems (MSX for example #1056033525922537542 message)

this is so cool 😄

after some coffee, will see what was the issue with Minix and Amiga core, it was long time ago since I tried it and can't really remember what was the issue exactly

[void belfry]

hmmm...

[robust monolith]

Good old Amiga, BSOD before it had been invented.

[strong yoke]

Are you using a 68000? Original 1.5 only supports that I think

[void belfry]

oh boy.... so this is FreeDOS running then some Linux image to somehow install W98 after...

[void belfry]

yes, tried 68000 only, different kickstart roms (thought my usual 3.2 would have to do)

[strong yoke]

Might want 1.3

[void belfry]

apparently it doesn't even want to boot from the floppy, though I think i did it correctly

[strong yoke]

Hm. I'll have a look later when I get home, I had completely forgotten it existed 😄

[void belfry]

right, don't think i tried 1.3 though

[strong yoke]

Kindly the Aminet version has the later 1.5.10 which supports a lot more https://aminet.net/package/misc/os/Minix_Amiga

[void belfry]

yup, that is the one I tried

[strong yoke]

Might bust out a real Amiga or two to compare

[void belfry]

tried to re-make the boot floppy unde WB1.3, doesn't boot and if tried to run directly:

[hollow estuary]

Yeah I've used it to install win98 on my itx llama

[void belfry]

Yeah, defo would work on that (itx llama). I tried to compile the kernel with math emulation for ao486, seems to work but now it's the rootfs it complains and goes into kernel panic

[hollow estuary]

Annoyingly it doesn't work 100% on the llama. There's something weird with detection of the install media on the Linux part of the install process and you have to reboot and retry multiple times for it to be detected. Not sure what the deal with that is

[ruby charm]

@hollow estuary Not exactly related, but since you seem to be into the Tinyllama as I am, have you tried Pinball Dreams or Pinball Illusions on it? SETSOUND.EXE resets the Llama immediately, even without any memory managers. Do you happen to have an idea on why?
Already tried slowing down CPU, disabling caches, limiting XMS to 16MB, etc

[hollow estuary]

Sorry haven't tried those games yet

[ruby charm]

Ok, tell me about your findings if you ever try them on the TinyLlama 🙂
I've been investigating the incompatibilities of the TinyLlama for more than a year now. We recently discovered that loading SMARTDRV in CONFIG.SYS fixed all EMS games that had problems previously, so Lemmings 2 and Elder Scrolls: Arena now work perfectly.
But Pinball Dreams /Fantasies / Illusions are resisting...

[hollow estuary]

I don't have a tinyllama, I've got an itxllama, although same SOM but I guess it'll be the same on both

[ruby charm]

Yes, the same problems are present in both due to the same SOM.
But that line works around the infuriating EMS problem we were seeing before 🙂

Whatever you find on the ITX Llama will be applicable to the TinyLlama.

[deft hemlock]

Will the C64 core ever support EasyFlash saves - or is it not possible? I wonder if anyone here knows more..?

[hollow ice]

At boot? I really, really, really need to find out why that first data response is ignored.

[hollow ice]

@void belfry first release https://github.com/mezantrop/i486SX_soft_FPU

[void belfry]

@hollow ice indeed, math emulation works but it still fails due to IDE errors when mounting rootfs

[proud pasture]

Is there a package similar to Amiga vision for the Zx Spectrum Next Core?
Also does anybody know if you still need/have to install on an SD card in the second SD slot? I'm new to trying out the computer cores and unsure about setting up this zx core. Amiga vision and X68000 are simple thanks to the available packs.

[copper slate]

Second sd cart slot is completely unused

[proud pasture]

Hmm I was reading the info on the GitHub...maybe I'm misunderstanding?

You may use secondary SD card (on I/O board) directly in this core. Make sure you've deleted/renamed ZXNext.vhd in the root and Games/ZXNext/boot.vhd. If core cannot find these files, then secondary SD card will be used instead.

[copper slate]

Oh, I mean that you don’t need it.

[proud pasture]

Ok thanks. I'll have a go at getting it running after work 👍

[elder cove]

Sorry I haven’t posted too much about new packs this last week - got about a dozen titles in progress, but several are waiting on finishing up work for supplemental content or reviews. (One’s requiring scanning about 60 different documents, for instance, but it’s an extra I’ve wanted to see done for a particular game for years.)

[young gust]

Hope all is well!

[vestal goblet]

if the original SunOS could run….

[hollow ice]

yeah, I think the original sgis were 68k as well? I’d love to have a sony news core too

[vestal goblet]

There was a local BBS in Springfield Illinois that ran under Minix on an Atari ST!

[hollow ice]

I am just happy that we have the sparcstation core…that is a rabbit hole in and of itself

[vestal goblet]

was just at the Comouter History Museum with some colleagues from Poland , and I told them how important Stanford University Networks was to the spread of the (arpa) internet. Putting a network card in workstations by default was heretical at the time.

[elder cove]

The earliest IRIS machines were, yes - the IRIS 1000-3000 series. I don’t think I’ve ever seen one in action, though.

Most of the later machines (Indigo/Indy/Octane/etc) were MIPS-based until they moved to Intel-based processors.

[hollow ice]

I know mame is focusing on the mips computers, I have no idea if any technical documentation still exists for the early ones

[vestal goblet]

Yea, because what are you preserving? Does the original software and assets for rendering the Owl in Labyrinth, or the knight in Young Sherlock Holmes still exist? (Or some other early CG character/film that was rendered on that hardware?)

[void belfry]

Doubling PPP speed on Minimig request got merged, please test (adjust speed in your TCP stack of choice to 230400 baud. I only tested with Miami/MiamiDX, but I don't see why it won't work with RoadShow or AmiTCP as well): #unstable-nightlies message

[strong yoke]

You can pull the sd from a real Next and pop it into the 2ndary SD slot and use the core that way, then pop it back into a Next. That’s the only current core that’ll use the slot I think.

Only “finished” core anyway. Maybe some of the incomplete Japanese PC cores do, I’m not sure

[void belfry]

think at some point the OCM MSX core needed it in first stages, but not anymore for quite a long time

[granite umbra]

https://github.com/JasonA-dev/LM80C_MiSTer/commit/b821cd2475e7ac2ebac5c581fb10e6a32a57aa59

[elder cove]

So, I’ve found a few titles with some pretty significant issues in ao486 I can’t seem to get fixed.

First is that I’m getting a black screen on the Sherlock Holmes: Consulting Detective games. Tried a couple different things, but I can’t seem to get past that.

Second, is that the lower scoreboard in Pinball Warriors isn’t appearing. The rest of the game plays fine, but I’m not entirely sure why that doesn’t appear - you just see the panning playfield in full screen, with glitching when you reach the bottom of the screen (which isn’t correct).

[elder cove]

One that really confuses me, however, is 8 Ball Deluxe. It should use the same engine as Royal Flush, another pack I’ve put together, but I just get a flashing cursor when loading the .EXE. I’ve tried multiple different installations, and got the same result.

[hollow ice]

I’ll take a look at Sherlock, I have been fixing unsupported ide commands and maybe that is the problem there. I need to figure out what is going on with the status command for sf2t, the faq says that some cd drives have issues and will exhibit that behavior.

Did you upload Sherlock already?

[cold crane]

I'm sure this has been asked a million times already...but is there any way to save in the X68000 core? Like if I create a profile in Castlevania, every time I reboot the game, the already included profiles are still there and my profile is gone again. I assume it's just not built into the core yet, but just checking! 🫡

[void belfry]

save the game before rebooting ? like on every other computer game 🙂

[cold crane]

I will have to figure out how to save then!

[void belfry]

i'm taking a look, for sure it should have some save menu or smth.. i guess 😄

[void belfry]

so far ESC pauses the game, but can't see any menu lol

@cold crane apparently it's either automatic save after each stage boss or when you die you'll have the option to save the game/profile

[void belfry]

Where/when do you get that black screen ?

used a template DOS 6.22 vhd, it didn't like my usual DOS 7.1 apparently

[void belfry]

that one also seems fine to me (works on a DOS 6.22 template or on my own 7.1)

[elder cove]

Hmm - there’s something different between our configurations, then. It’s as soon as I boot the game for both on my 6.22 config.

Are you using CHD, ISO, or BIN/CUE media for the CD?

I’ve primarily been testing with Sherlock Holmes Consulting Detective Volumes 2 & 3, as the later games are less widely ported.

[elder cove]

And for 8 Ball Deluxe, are you installing from images of the original media or playing it from a pre installed folder? I know there’s a V1 and V2 of that one - I’ve tried both, though I’m not sure if I tried installing V1 from original media.

[void belfry]

For Sherlock Holmes only tried volume 1, didn't install anything, just booted the DOS vhd then ran it off CD image *some bin/cue found on Archives)

For 8 Ball Deluxe, same, got it from some PinballMania iso CD and just ran it off CD

[elder cove]

Yep, looks like Volume 1 is working for me as well - 2 and 3 just give me the black screen. (Again, weird because they should all use the same engine.)

[void belfry]

weird, will have a look at them too

right, tried vol 3 and it gives me the same black screen...

smth is off with the image, only seeing 160 kB of data under DOS

under W95 a lot more appear

thinking to use W95 to copy over the files on some DOS template then see if it works

[void belfry]

probably some weird CD image... for now still copying over the files

[void belfry]

aaand i'm out of space on that DOS template 😄

converted the CD image to CHD, same issues under DOS..

@void belfry is the winnt ide driver just redirecting hard drive requests through the bios?

[blissful bison]

Someday, FPGA will simulate a computer that can emulate and play NES or SNES games.

[granite umbra]

Ao486 can run old nes emulator

[ruby charm]

Looking at the Lemmings 2 VHD in the 0MHz collection, I see that working sound requires 15Mhz + L1 Cache OFF + L2 Cache OFF, which makes the game insanely slow to load and move through the menus.
Are those requirements real? I mean, I had the game working with sound back in the day on a 486 DX2@66Mhz computer...
So, why the strange 15Mhz+No Caches requirement on the ao486 core?? Makes no sense...

I have even seen that game run on Pentium-class PCs with audio

[cold crane]

Bummer! For some reason, the 0MHz collection no longer shows a video signal on my TV. I wonder if it has something to do with my new receiver, which my MiSTer is hooked up to. Odd that it wouldn't work though considering it supports 4K 120hz and VRR. And nothing else on my MiSTer has any issues running through it.

I forget, what type of video signal or resolution does the 0MHz collection use?

[exotic prairie]

My denon receiver hates certain refresh rates. 53.5hz. 60.6hz. 57.3hz. Does vrr, 8k, all the fixings, but can’t show psychic 5 without triple buffering.

[cold crane]

I seem to have been able to fix it by forcing the ao486 core to use 1080p (video mode 8).

[fleet cave]

what were you using before?

[cold crane]

1440p 4:3 (video mode 12)

Always worked when I used to have my MiSTer plugged directly into the TV.

And works for every other core going through my receiver.

But for some reason ao486 just doesn't agree with video mode 12 going through my receiver. But works fine when hooked directly into the TV.

Different refresh rates also work fine going through the receiver. Like arcade stuff like Irem M72 games, Wonderswan, and even the ao486 core right now at 70.1Hz.

I have noticed another random issue though. For some reason the F12 key on my keyboard no longer brings up the OSD? Very odd.

[summer dragon]

try holding windows key and then pressing F12

[cold crane]

That worked. Was it always like that? It's been awhile since I last used a keyboard on my MiSTer.

[summer dragon]

it’s only like that in (some?) computer cores I think

I feel like sometimes F12 works and sometimes you need to hold the Windows key

[fleet cave]

ao486, pcxt and archie I think require Win+F12

Thanks mate, will resume SLIP tests over this prolonged weekend 🙂

I've not tested the kernel boots yet, can't do that until this evening..

it probably boots fine though

[void belfry]

Think this modification should be made permanent tbh, a lot of old OSes can do just SLIP and not PPP

[thick pendant]

i think this is all i did last time

maybe i should have put in the 6 bit thing as well?

[void belfry]

don't know, but won't hurt, i think. Last time iirc I included that as well

[thick pendant]

I really did not want to get one I had my laptop in a backpack with a bottle of Gatorade and someone cut off my truck and sent backpack flying and the laptop got soaked in electrolytes and never booted again. it was a i7 with RTX 2060

[void belfry]

[thick pendant]

this one is a i9-14900HX with RTX 4070 so it can compile kernel with "-j24"

[void belfry]

[thick pendant]

oh, i've not put quartus on it yet. I bet it still takes a while, only parts of the synth process seems to use multiple cores

[stiff fern]

I had submitted a PR to add SLIP support, and it was rejected. I believe Sorg said a PPP driver should be written for the OS instead.

riiight... who the heck will write a PPP driver for old Minix or SunOs or whatever 😄

even if it would be possible...

[stiff fern]

My changes are still in my personal GitHub account.

[void belfry]

have to review my notes to see how many OSes for what cores I found to have SLIP

might be wrong, but think even C64 has an use for SLIP

[thick pendant]

i originally used SLIP with Windows95 because i used university account and thats all they offered

we probably could compile SLIRP in user-space

[karmic fog]

what's the downside of having SLIP enabled in the kernel

[void belfry]

none

[thick pendant]

maybe use a few extra kb

[karmic fog]

😦

[fleet cave]

can't you just build it as a module?

[thick pendant]

could i suppose

[void belfry]

ELKS/Minix - works as well on XT core, supports serial and SLIP connectivity. You need to modify MiSTer linux kernel for SLIP

Now I remember the PDP2011 core needed SLIP as well

https://misterfpga.org/viewtopic.php?p=65553 3 years now :))

[thick pendant]

oh, looks like we also need "slattach"

looks like you can get slattach from debian "net-tools" deb

[void belfry]

isn't already present on MiSTer Linux iirc ?

[void belfry]

it is 🙂

[thick pendant]

ah. cool

well, if we are going to include "slattach" then why not include kernel support.... seems like a no brainer, but I don't want try and make that point otherwise next linux.img will probably omit it (slattach I mean)

[hollow ice]

@fleet cave I haven’t done done any debugging recently, but any recommendations on where to look in regards to the ide implementation to understand why the bios reading of the hard drive seems to work, up to the point where these operating systems make a call for the first sector of data, it is returned (at least according to the debug log from main) but the core never seems to see it? I assume that is when the OS switches to its IDE driver.

[fleet cave]

no not really. other than some intense debugging on the os side in an emulator to see if you can figure out what breaks/works for the os

the other wrinkle is...maybe the bios being used by mister just sucks

[hollow ice]

well, there is that, plus the ide implementation sort of … is not great due to the way interrupts are passed back and forth. What is frustrating is I cleaned up the RESET flow a while back, and then lost those changes, which really put a damper on my enthusiasm

But once the CPU is in protected mode I don’t think you can use the BIOS for access anymore?

I am not an x86 wizard

[thick pendant]

You can, like in the case of DOS extenders you get the "int86" function which switches "unreal mode" or "v86" mode, but its a lot of overhead for OS level code, so doubt that is done

[fleet cave]

yeah, I think I'm more saying that i don't know if what you set in main is 'clean' pass through. the core has some component of an ide controller in it that I've never fully looked at.

this ends with someone booting this stuff in like pcemu and somehow dumping ide registers. that sounds like work tho

[hollow ice]

Yeah. The core ide controller is exposed as if it is on the pci bus. It looks mostly right for my limited knowledge.

The bios implementation seems to reach out through the correct memory range, but… once again I am no x86 wizard. Block diagram wise it looks like it should work.

Millennium Auction is going up:

Definitely a unique game - sort of an art auction simulator based on what they thought the future would be like in the '90s.

It does a lot of interesting things to put it beyond just your average simulation title, though, taking some influence from point-and-click adventures with a lot of focus on the impact of the media & these wild (and occasionally quite surreal) character back-and-forths between the fictional auction bidders you play as. Thanks to @young gust for the recommendation, as it otherwise wouldn't have been on my radar to check out.

I've also finalized the 3-game lineup for a sequel to my April Fool's Pack, Bad Games Vol. 2 - and trust me, the third one besides Maabus and Ninja Nannie has a wild name attached to it. Will have more info on that soon.

Meet Mediaband is going up:

[elder cove]

Long story short, Meet Mediaband’s a real odd one. It was created by the co-designer of the Director engine, which was also used by a significant number of other games (including Eastern Mind, Milo, Frankenstein: TTEOTM, The Dark Eye, and more).

I wrote a pretty significant writeup for this one, and the documentation included covers quite a bit more of the game’s history (including the full script for the unproduced tie-in film & what the full 2-CD plan for the game originally looked like).

hello everyone, could anyone tell me if there's an existing .hdf file for the amiga game attack doom. i know theres a .lha file but it seems like a lot of work to create one from scratch.

[void belfry]

I dunno about that game and if it is in AmigaVision, but if you have a working AmigaOS hdf (including mentioned AmigaVision), simply transfer that LHA archive (shared folder is an option) and just extract it to a folder to your convenience (lha -x archive.lha)

[honest latch]

@void belfry thank you for your response. i do have an .hdf file, so is all thats needed is to decompress the .lha file, copy the contents into the .hdf virtual drive along with the doom .wad files. would i also need kickstart files copied as well?

[void belfry]

Kickstart roms should be in the /media/fat/games/Amiga/ folder on your MiSTer

Announcing the third game in my upcoming Bad Games Pack Vol. 2, DEVO - Adventures of the Smart Patrol:

[elder cove]

Now, you probably had no idea that DEVO, the band most famous for songs like "Whip It", made a game. But they did - with InScape (the developers behind The Dark Eye) giving the band's writer, Mark Mothersbaugh, full creative control over the project.

This was a unilaterally bad idea on InScape's part, which would eventually borderline bankrupt the company and collapse the studio from this single game alone. It is one of the most stupidly insane adventure games I've ever played, and just about a reference-class example on what not to do in game design. (At the same time, it is so patently bizarre on every level that it absolutely deserves a pack.)

[lunar trellis]

Oh wow! I didn't know Devo had a game

That's a whole weird subgenre, bands who released CD ROM games in the 90s. I remember when a mate got a Mac in the mid 90s it came with a game about the Rednecks who sung Cotton Eye Joe, which was a point and click where you had to go about a western town looking for the band members and they would play FMVs when things happened. Not sure if that came out on PC, probably

I know The Residents had CD ROM games which I imagine are suitably surreal and unnerving

https://en.m.wikipedia.org/wiki/The_Residents:_Freak_Show

[jaunty iron]

It absolutely is, you nailed it

[strong yoke]

Before that in the 80s there was Frankie Goes To Hollywood, a very odd set of minigames

[lunar trellis]

I wonder what the specs needed for Freak Show are, probably needs a Pentium being from 94

All I can find is it needs Windows 3.1

They released another one the year later

https://en.m.wikipedia.org/wiki/Bad_Day_on_the_Midway

[elder cove]

I’ve actually been working on a Residents pack. Freak Show runs well, Bad Day on the Midway works but is a bit slow.

Haven’t been able to get Gingerbread Man working, though - it just throws an error on startup.

[lunar trellis]

Oh wow, that's ace you were already looking at those!

Ah yes, this was indeed a thing and did get a release for 3.1

https://youtu.be/E7GnCnOPMrU?si=jvy1WjBDOgOudXYl

[elder cove]

That is a wild choice of title for that game lol - I’ll look into it

If there’s interest, I can start putting together some more of these musician games, too - Telepathy: Out There also comes to mind as a really unusual one

[elder cove]

Rednex works pretty well under ao486 on an initial test. Telepathy seems to be having some issues recognizing an image of the CD - I’ll try a rebuild tomorrow, see if that helps.

[lunar trellis]

Man, I never thought I would have the chance to relive those weird memories of trying to beat the Rednex game that came bundled with my mate's Mac, thirty years ago...

[karmic fog]

@elder cove d'ya think Cosmology of Kyoto is playable on ao486?

if so, that'd be a great candidate for 0MHz

also maybe something to keep in mind for ShapeShifter once we get there

or a 0MHz "community extension", whatever we're calling it. it's a a good search term either way

[elder cove]

Haven’t tested it yet, but that’s on the list to try out.

[elder cove]

Running it now - so far, seems to play great under Windows 3.1 on the core.

[copper slate]

@elder cove if you want to try an absolutely bonkers game, check out Space Kids. It’s for MSDOS - https://en.m.wikipedia.org/wiki/SpaceKids

[elder cove]

I’d forgotten about Space Kids - that is a weird one. Evryware’s games from around that time had a very specific kind of “morph-ey” style, sort of Rayman meets Mode 7.

For that and its sequel, 1996’s Space Dude, I think I’ve only ever played the demo - I don’t think I’ve ever tried the full version.

Dumb question but new to X6800. Why do I have sound in almost every game except Castlevania? Sound effects are fine, no music though.

[hardy kindle]

That did it, ty for the help!

[mental moat]

With AO486, can you use PPP and a MT32-pi at the same time? I don't yet have a mt32-pi so I can't try it to check.

[copper slate]

What’s PPP

[mental moat]

Network/internet access, it acts like a dial up modem.

Basically I want to be able to use midi and networking at the same time. It doesn't seem to be possible when using midilink with fluidsynth running on the de10-nano, I'm hoping that getting an MT32-pi will solve this issue.

[exotic prairie]

PPP doesn't use the SNAC port, yeah? Just uses the de10's ethernet port?

if so, then yes, that should solve the problem

but even if it didin't, you should get an mt32 pi

[mental moat]

PPP doesn't use the snac port, but you do set the UART port to PPP to make it work, which I think might need to be set to something else to make MT32-pi work.

I guess my question is more specifically, what does UART (see screenshot) need to be set to in order to make MT32-pi work?

I do plan to get an MT32-pi either way though :p this just influences where in my list of priorities it sits.

[exotic prairie]

Mt32pi has its own menu item

[fleet cave]

yeah, the uart is for other stuff, like doing midi to a software synth or doing midi over the network. or maybe even actual music production if you are one of those people

[mental moat]

Awesome! That's great then, I should be able to use UART for PPP at the same time as the mt32-pi is used for midi

Which should make multi player Warcraft 1 & 2 possible 😮

Got a request for you smart people here. LSL7 on the 0Mhz pack slows down to an absolute crawl when you get to the cruise ship lobby. Is that fixable with your computer magic?

[elder cove]

Hmm - possibly. I’ll take a look at it.

Worst case scenario, you should also be able to run it natively on the ARM CPU via ScummVM, too.

[elder cove]

Going to start by testing the Windows 3.x version - see how it runs in comparison. (For example, I found that the Windows version of King’s Quest VII ran significantly better than the DOS one - that may also hold true for LSL7, considering they should both be using the same version of the Sierra SCI engine.)

I’ve played a good few hours into this one under 3.1. Generally a much better experience, though still a bit slow in places.

[void belfry]

genuinely curious what those commands did 😄

[strong yoke]

The original, UK version included commands for file transfer entitled |SUCK and |BLOW, which used a proprietary Amstrad format similar to XModem-1k but, annoyingly, subtly incompatible. These commands were reputedly renamed for the US edition to avoid causing offence. so may be apocryphal

[void belfry]

yeah, read some more on cpc-wiki (and about the 3rd party rs232 interfaces/modems)

[strong yoke]

As one indeed does 🙂

[void belfry]

hope one day will have serial connection available to Amstrad core too, guess would be fun to browse BBSes from this machine too

[elder cove]

There were U.S. versions of the Amstrad 8-bit machines?

First I’ve heard that. I had assumed they were PAL-exclusive.

[void belfry]

apparently: CPC 6128 was released on 13 June 1985 and initially only sold in the US 👀 didn't know about that (well, I am a newbie on many systems, Amstrad being one of them too)

also find this fascinating as well: The CPC 472 was a spanish version of the CPC 464 with additional (nonfunctional) 8 KB RAM. The reason for this was that Amstrad wanted to circumvent a Spanish law that levied an extra tax for machines with 64KB or less of memory; thus, they upped the spec to 72KB by including an additional 8KB though this extra memory was not functional.

[ruby charm]

This is very well known here in Spain. It was true: our 472's had memory that couldn't be used at all 😄

[void belfry]

that in extension explains the MSX2 adoption in Spain

learned smth new today on computing history 😄 Moral of the day: don't mess with nerds 😛

From |SUCK and |BLOW to weird Spanish law and ways to avoid it.. Amstrad sure had its history lol (and great/unconventional minds as well behind)

In comparison, DEVO is, in my mind, one of the definitive candidates for how not to make a game. Like, it should be taught in classes as an example of almost everything to do wrong.

It’s batshit insane - at one point, the game expects you to memorize the locations in the game of specific pages from a 200-page book (which you’re not provided with in complete form until after you complete the game, and which changes in each area every ingame hour, which passes either like every 10 minutes or once you trigger any specific event to leave an area) in order to time travel across the game to teleport into a room so that you can stop a malicious paparazzi who’s allied with a bunch of gangsters in Pilgrim hats which serve as the main antagonists. (He’s not actually wearing one himself, however, making it unclear he’s the one you actually need to target except by catching a specific off-hand cutscene or by trial & error).

You access this weird time-travel world by finding a bunch of chopped-up DEVO video clips (which all awkwardly cut off like 30 seconds in) in hidden spots placed in ingame 1-hour blocks and then use a gateway hidden in the images (or, oddly, the back door of a donut shop) to travel to this weird, nonsensical backrooms dimension.

Third and final game in the Bad Games Vol. 2 pack, Maabus, is going up:

I'll be honest - I didn't find this one as bad as its reputation would have you believe. Give it a look!

[young gust]

The best kind of trash 😂

[woven lava]

just from the cover, that Maabus looks like the game of the year compared to smart patrol

[copper slate]

How do you pronounce ZX Spectrum?

[feral dagger]

Zed Ex Spectrum

[copper slate]

But the processor is from the US so wouldn’t it be the Zee Ecks Spectrum?

[frosty cosmos]

Too many clowns breakfasted, Robby? 🤡

[copper slate]

lmao yes, don’t shame me

[elder cove]

Cosmology of Kyoto is going up:

[woven lava]

who is familiar with making 0Mhz packs? I have a translated version of a game that is not commonly avaialble (and RomHacking refused my upload as they don't take PC games)

(English version of Explora II i.e. Chrono Quest II)

the PC version never got translated, I translated it using the Amiga text + some cleanups

[void belfry]

There are different sized DOS/Win 0MHz template VHDs on archives, get them and use what you think is appropriate in size for the game installation. For the MGL part, think you can just modify an existing one ? I don't use MGLs tbh, so not much clue there

[void belfry]

testing Wizardry Gold (Win3x with Win32s and Video for Windows OR W95). So far FMVs are fine (under W95) but there seems to absolutely need also the DOS mouse driver loaded beforehand).

[void belfry]

sadly not so much playable 😦 slow and hanged at momments (both under W3x or 95)

[elder cove]

Awesome! Here’s my advice on making a pack:

1. Seek out the MS-DOS 6.22 and Windows 3.1 VHD templates for MiSTerFPGA. They include basic installations of various sizes for both OSes you can build off of. (If you need a Windows 95 installation, let me know - I can direct you in the way of a 95 prebuilt package, but 3.1 is preferred first as it is faster on most titles.)
2. Compress the disc image with chdman on your PC. This comes with the current build of MAME, and can be done with the command line - copy the CD image into the same directory as the chdman executable, and run the following command (replacing gamename with your game’s file name):
   chdman createcd -i “gamename.iso” -o “gamename.chd”
3. Place the .VHD image and .CHD compressed CD image in a subdirectory with the title in lowercase in /games/ao486/media (ie. /games/ao486/media/chrono quest ii).
4. For your first pack, copy a .MGL from an existing pack with both a CD image and a .VHD hard drive image. (Area D is a good example of the newer format.) Open it in a text editor. Replace the title of the game after “ao486 - “ in the header with your new game’s title. Then, replace the VHD and CHD directories with the locations where your new game files are stored.
5. Copy the .MGL to a subdirectory titled _DOS Games, _Win 3.1 Games, or _Win 95 Games, depending on the system being used. Copy this folder to the root of the SD card. Copy the games/ao486/media/game name folder to the root of your SD card or an external storage device.
6. Install the game as usual. If you’re used to more modern versions of Windows, you can browse your CD under 3.1 in Main-File Manager.
7. For the auto-loading, add the startup commands to AUTOEXEC.BAT for DOS titles. For games running under Windows 3.1, copy the main file for loading the program to the Startup directory via the File menu.
8. Once it’s installed and you’ve verified it’s working, overwrite the version of the .vhd on your hard drive with the new installed version installed on the MiSTer.
9. Compress the two folders on your hard drive. (Previous versions of the standard also featured a .cfg that was found to be unnecessary in testing for 90% of configs - I’ve excluded it in this guide, but it may be necessary if you do a lot of settings tweaks. If so, copy the ao486 - gamename.cfg file from the /cfg directory on the MiSTer’s SD card and compress it in the same file with these two folders in a /cfg directory.)

10. Congrats - you’ve made a 0MHz config! Pick out a neat piece of boxart for it (I’d recommend square format, if possible, but whatever’s available), and that is all set.

[void belfry]

Mods, please pin the above @elder cove post 🙂 Excellent write-up, mate 🍻

[copper slate]

Maybe, what’s in it for me?

[void belfry]

https://tenor.com/view/butter-gif-2922169995827680567

A spanking from all community if you don't

[copper slate]

it was a great suggestion, thank you

[void belfry]

gonna try under Win NT4 just for fun (already excluding W98), but I really really doubt it would work lol

[void belfry]

hmm.. it is not ideal, but to some degrees actually "playable". meaning I could actually move around, fight and lose first battle 😄 but yeah, not a candidate for the present

ofc, had to load beforehand a DOS mouse driver under NT prior starting the game.. weird stuff lol, didn't played this before (from what I know a revamped Wiz7)

[woven lava]

thank you! its not a large game, one small HDD image of DOS and a mouse driver will be enough

[elder cove]

Sounds good! Same basic principle, just mount the .VHD and copy the install for the game in. Once you’ve booted into the .VHD in the config, use the edit AUTOEXEC.BAT command to view the file, and add the commands at the end to run the game.

[copper slate]

I imagine you ran out of text so you couldn’t include step 10 on your first post, correct?

[summer dragon]

if you only need to make basic DOS VHDs and are fine with DOS 7.1, you can also use my VHD Kitchen tool posted on the forum 🫡

[hollow estuary]

@summer dragon what's the current version of VHD Kitchen?

[feral shore]

now how's about vesa/svga with univbe and the et4000 bios on the ao486 core, does it speed anything up?

or was it et6000

[fast kraken]

flynn had that all sussed out in top300

i think there was a thread about it on the forum

he got some big improvements in fastdoom

[feral shore]

thanks I'll look at the top300 git

[fast kraken]

it wont make duke3d run fast enough to be seriously playable sadly, but maybe other games can get enough of a boost to go from bad to playable

fastdoom got enough to lock 35fps basically all the time iirc

[void belfry]

https://misterfpga.org/viewtopic.php?t=2780

[fast kraken]

oh sorry i guess it was alexougton who did most of the legwork

[void belfry]

speaking of that list in the forum post, I remember Versailles game benefited a bit of boost from Q87 emulator.

[summer dragon]

0.34

it’s the only version I have posted

@feral shore i have a working drag and drag univbe setup…actually, I think Elphive might have it on archive too

@feral shore it’s also included in my rayman vhd on archive

[young gust]

Another Windows 3.1 game that needs to go up is Iron Helix, and Blown Away

[short finch]

https://github.com/MiSTer-devel/X68000_MiSTer/issues/43

So everyone can enjoy it.

Kudos to @crisp hinge

[feral shore]

@summer dragon thanks, i'll have a look!

[woven lava]

whats the command in SYSCTL to control ao486 speed?

I want to set it at "PC AT-10Mhz"

[woven lava]

nevermind I figured it out

[modest skiff]

Can you use the SYSCTL command to set the predefined settings like PC AT-10MHZ?

[summer dragon]

yeah I didn’t think you could do that with sysctl 🤔

[woven lava]

no

but that setting corresponds to a specific mhz and cache config

so I set those instead

https://docs.google.com/spreadsheets/d/1uL0wETXqfy4AwQzi1xaKaOKHQTz_RUbX1GGcZXn7Ac4

the presets come from these tests ^ 😁

[modest skiff]

Thank you. I requested access to the Google Sheet.

[woven lava]

oh sorry, didnt realize it was not shared

[modest skiff]

Thanks, your Google sheet will come in handy.

[elder cove]

Requested access as well.

[elder cove]

Telepathy - Out There is going up:

This is another crazy, surreal oddity I sort of stumbled on by accident - turns out, it has some surprisingly big names attached to it. I go into it more in my description on this one, but TL:DR - a bunch of people who worked with Peter Gabriel made their own side-group, created this, and then all proceeded to become pretty successful names in their own right doing wildly divergent things.

[lunar trellis]

Great to see these weirdo games I never heard of getting the 0mhz treatment. Top work.

Where are we at with 0mhz coverage of the Top 300 titles? Are they all done now or are there still some in there that haven't gotten 0mhz versions?

[feral shore]

i thought they were competing collections

[strong yoke]

Top 300 (and the rest) are moribund, I believe. Still great 🙂

Flynnsbit did amazing work on those

[feral shore]

aha

[lunar trellis]

Yeah it was a brilliant set, and really paved the way for so many of us being able to easily play games on the 486 core. 0mhz format makes it even easier for end users and should at some point make Top 300 redundant, if we aren't at that point already

[summer dragon]

that’s a really good question and one I’ll add to my to do list!

progress is slow at the moment on updating the pack and getting all the community stuff added, but it is happening

[lunar trellis]

Great work all round with these

[hollow ice]

Who was working on the zzt collection?

[lunar trellis]

What is the zzt collection?

There was also the Shareware collection thinking about it, not sure how many titles were in that and if it would be worth 0mhz that. Probably a lot of effort, but could be more widely shared with the titles being shareware

[elder cove]

I am - it’s in progress, but if anyone wants to help once I get the first volume out, it’s a pretty massive collection.

ZZT is a game engine, and one of the first titles ever released by Epic. There are decades of fangames made in the engine (including others in slightly modified versions of the engine like Weave, Super ZZT, etc.), so I’m working on the main engine games by year and splitting the sub-engines into their own collections. (This is how the Museum of ZZT organizes their sets, too, so it’s an easier way to iterate through the collections.)

I’m building them per-game as floppy disks so that they auto boot, as each title should fit together with the engine on a disk. But, because of that, it’s a heck of a project to put together.

[hollow ice]

Interesting. I wonder if there is a way to automate the downloading and extracting to newly created disk. I know bas on the forum created a vhd creator, wonder if it will do fdd

It is shocking that the popularity is still there, I think the last time I played any variant was probably in 94/95

Granted, you might be able to just create 4mbish vhds with his tool

Not sure what the minimum size is

[elder cove]

These games are tiny - each individual title complete with the engine is about 500KB. If it's possible to make hard disk images at a size of around 2MB or less, that would help a lot.

Currently, the main reason I'm using floppy disks is because assembling the game from a DOS boot disk results in a game file that's significantly smaller in size. However, it currently means manipulating files with WinImage (which tends to be a bit finicky, and as such is a bit slower of a process.)

[elder cove]

Star Trek: The Next Generation Interactive Technical Manual is going up:

This is a title I have a lot of nostalgia for - it's an explorable tour of the NCC-1701D Enterprise, featuring explorable 360-degree panoramas of the original sets.

It describes in extensive detail how all of the individual systems on the ship work, gives in-depth descriptions for hundreds of items & controls across the ship, and gives you a Transit Mode that walks you between any room in the ship with a realtime map so that you can visualize how all of the different locations in the show are connected together.

[hollow ice]

@elder cove it looks like bas does support floppies. https://github.com/doscontainer/doscontainer might be an easy way to script the creation of all the zzt disks

[elder cove]

Cool! Are there any example TOML files that better show what doscontainer is looking for?

The documentation on that, while describing the functions of the instructions it uses reasonably well, doesn’t really make the format 100% clear.

[woven lava]

I've been thinking about the best way to make Apple IIe games more accessible...
there is already Total Replay, Instant Replay, and Pitch Dark (vol 1 and 2) but they are missing many larger titles

giviing those the 0mhz treatment could help but I'm not sure it would add a lot,
as you still will need to read the manual and swap floppies. E.g. Ultima IV, Wizardry, ACS, Wasteland, etc.

at least several of these exist for PC or other platforms, so they are playable

[hollow ice]

Not sure, I haven’t used it. I can forward questions to the forum if you don’t have an account and don’t want to make one.

Right now you are one of the most active archivists, so feels like you would have a lot of useful input for him.

[robust monolith]

Be quite good that, cos it's about 30 years since I last tried an apple 2e, and can't remember a thing howo to load stuff etc.

[elder cove]

I sent a message asking if he has any example config files for operation he would be willing to provide. Will see if he gets back.

[karmic fog]

4am's 'Wizard Replay' has all retail Wizardry titles for Apple II plus extras

[hollow ice]

Sounds good. Hopefully it helps out- I am looking forward to see if I can spark some deep memories with the collection 😄

[karmic fog]

@woven lava most games people would be interested will already have a ProDOS conversion so you wouldn't need to mess with floppies at all if you don't want to

[summer dragon]

at least in Windows disk management, the smallest VHDs you can make are 3MB

[hollow ice]

Elphive, looks like he is still a ways away from being usable, that is a bit of a shame.

[woven lava]

I didn't know! I need to check that out, thanks!

[woven lava]

well, it's also about helping discover games outside of those common ones

eg. Adventure Construction Set is a nice game but there are many bad dumps of it (I had to try a few versions before I found a good one)

[karmic fog]

you'll not go wrong with 4am / san inc generally

that game might not have a prodos conversion - i can't see one at a quick glance, but it does have a clean crack by 4am and san inc

everything else is a crapshoot but those folks are very thorough

[woven lava]

yes 4am is great

I need to check if they have a version of the obscure ultima clones

there's at least one Korean and two French Ultima-likes that I've been meaning to check out

[karmic fog]

oh wow

[woven lava]

granted, other than me there will be only 3 people who will want to try it 😅

[elder cove]

I had no idea there even was Korean-language Apple II software. Definitely a unique piece of history.

[woven lava]

there are at least 2 known games, but one is lost media - nothing online other than a screenshot

there was a naver post about it but I see it's been taken offline and not backed up in the wayback machine 😰

[tall grotto]

For a second I thought a black monkey was in the top left corner

[hollow ridge]

I was posting in #dev-talk before about this, but maybe it’s better to post little updates here occasionally instead.

I’ve been working on an FPGA core for Uxn / Varvara (a fantasy computer platform by hundredrabbits). I started out on the Pocket, but for the last month or so, I’ve been porting it to MiSTer.

I just recently got the USB mouse and keyboard hooked up, and properly reading the ps2 signals from the MiSTer framework. I still need to figure out the arrow keys, but it’s getting there!

[tulip atlas]

It is not working for me

The CD shows as mounted, but it always gives the cannot read error.

[elder cove]

Weird - is anyone else having this issue?

[young gust]

I'll try it out after dinner n report back

[elder cove]

Thanks - so far, I can’t replicate this issue on my end. Even having the disc replaced with another image gives a different message, so it definitely seems a bit unusual, especially if it mounts under Windows 3.1.

[tulip atlas]

It seems to not mount the cd. When I try to read the dir of d:, I get an error.

"CDR101: Not ready reading drive D"

AO486 v241227
MiSTer v250305

[elder cove]

Hmm. I’m able to run it fine under 241227 on my machine - I also tested it under 250113 and 250224. I’m wondering if you might have a corrupted file.

Try deleting the old .chd file in the games/media/star trek tng technical manual folder and replacing it with a new copy of the file from the .7z.

@young gust How’s it running on your end?

[young gust]

Booting up my MiSTer right now.

Runs fine here.

[tulip atlas]

If I don't use a .chd, .bin/.cue instead, it works.

Maybe .chd doesn't work from USB hdd?

I have my /games/ao486 on /media/usb0.

Somehow .chd doesn't work for me, in ao486

Are you guys using official stable AO486 v241227?

[young gust]

I'm running mine from a USB HDD

in .chd

[tulip atlas]

Weird.

[elder cove]

I run my games off of a USB thumb drive, so pretty similar on my end, too

[young gust]

I'm using the latest unstable mister main

maybe there was a mess up during the download process

maybe delete that one, and re download it

Probably grasping at straws here but i dunno what else to try

[tulip atlas]

Already tried that (redownloading and copying .chd)

I will keep an eye on it, but since it works with .bin/.cue, no biggie

[elder cove]

I use 250113 for ao486 and the latest stable main, though I also test with the current stable and latest ao486 versions for these packs.

That’s generally due to it being a bit more reliable on my machine, though, as my IO board is one of the ones that has visual issues on the 241227 build. (Certain games like Rayman, however, require the newer 250224 - I’ve just found that version to have crashing issues on occasion with certain Windows 3.x titles at 90MHz.)

[young gust]

do you have any issues with other .chd?

[tulip atlas]

The .chd included with 0MHz Telepathy Out There works fine.

[young gust]

Man that's really weird

[tall grotto]

That's awesome! Keep it up! You're doing great!

[round token]

Question for the amiga fans, and/or amiga vision users. Mucking about with neon68k for sharp i ran into asteriods. Played it a bit and that reminded me i used to have an asteroids version on my amiga bitd. So i fired up amiga vision aaaaand it's not there. So i am guessing this was either a homebrew or maybe game with a cover disk OR it is somewhere in the wonderfull collection of games, but just under another name. Anyone got an idea?

it wasn't on err to be sure a certain yellow fruit website, but i did find a yt vid: https://www.youtube.com/watch?v=8lw1GQ5boEc

[karmic fog]

@round token try the name "Cabaret Asteroids"

it's there on lemonamiga

not sure about amigavision

[tulip atlas]

It suddenly works now.

All I did was to rename the .chd, and rename it back.

[tulip atlas]

Some weird filesystem problem I guess.

[copper slate]

I just got the file and it’s all working great on my end, thanks!

[copper slate]

What’s the keyboard command to clear a loaded IDE drive in ao486?

I thought it was backspace but that just exits the core menu for me

[jaunty iron]

it is, but you have to be actively in the menu to select a file to load for that drive first, not just hovering over the drive option in the menu.

[undone anvil]

Fascinating! Looking forward to trying it out!

[copper slate]

Ohhhhhhh, thank you!

[hollow ridge]

Here’s a video I took about a couple weeks ago, of the core running a bunch of demos and test ROMs 🙂

It’s in fairly good shape for what’s there, but it’s still missing some big features like sound and save state support. I also have some lingering issues with reset, for ROMs above a certain size, but I have an idea of what the issue might be.

I think I could make a test build in maybe a couple weeks. It might still be fun to play around with it, even with everything that’s missing / imperfect! I also really should make sure that it works well on a CRT too, before releasing it. The video signaling is very close to the Template_MiSTer example project, just with fewer active horizontal pixels, so I believe it should work fine (famous last words 😅 ), but I should double-check

[undone anvil]

The idea of fantasy systems implemented into FPGA always fascinated me. Just like homebrew games for old systems, only we're getting homebrew systems. It's good stuff!

[woven lava]

https://www.linusakesson.net/scene/parallelogram/index.php

there are even FPGA demos ^

I hope he ports it to MiSTer one day...

(demo starts at 1:40 of the video embedded in the page)

[elder cove]

In a similar vein, I would love to see someone tackle a Commander X16 core on MiSTer.

The VERA graphics chip for it is an open source FPGA design, and I think most (all?) of the other chips on the board have existing implementations in FPGA.

[undone anvil]

I would love to see that as well

Another thing that would be neat is if TIC-80 were implemented as an FPGA core, but I'm guessing for that you'd need to build a CPU from scratch that natively handles Lua opcodes.

[woven lava]

looking at the specs of the X16, I kind of want to see a SuperGrafx + CD fantasy "computer" with a keyboard and external storage added

the platform already supports a mouse and keyboard (the keyboard was never released), for storage maybe something can be done based on the backup solutions that existed for it

that would be a very capable 8-bit computer and it could play existing HuCards + CDs

(it wouldn't have any rotation abilities though - the hardware never got that far until the PC-FX)

[hollow ice]

@lyric dagger did an x16ish core, but there were concerns about the bios so I don’t think he ever buttoned it up?

[fleet cave]

yeah, the x16 uses some components with commercial licenses that the x16 project licensed

I dunno how different this is than any other bios situation on the mister tho

[woven lava]

there is an active business selling produts with that BIOS right now... as opposed to a BIOS from an out-of-production machine

[lyric dagger]

I only ever had the X16 running in a Verilator sim.

I didn't bother turning into a proper MiSTer core, because I thought the whole "license" thing with the BIOS was kind of ridiculous.

https://github.com/ElectronAsh/sim_x16

The full source code for the X16 BIOS is on their own github.

That's where I compiled it from.

The BINARY of the same BIOS is even included with their Windows emulator.

I don't get how they can really enforce people not sharing the BIOS / source, when it's freely available on github already?

Well, I guess somebody on the X16 discord said they "Just don't really like it" and "Would be annoyed if you kept posting about it here" (paraphrasing).

So that was it really. I eventually put the code I had on github, and moved on. lol

It was fun to mess with some of the simple demos for a while, and it could be interesting to try coding something for that system.

But the whole BIOS thing put me off.

You would think if parts of the BIOS are "licensed", they would have made more of a point of not sharing the source code, and only had a binary?

Or, even had some kind of lockout / license keys, but that would have annoyed even more people.

[woven lava]

we need a name for "open source" projects where people get salty if you do take advantage of the open license...

Open Salt Software

[fleet cave]

it's not an open license tho

just because the source is out there doesn't mean you can use it

[lyric dagger]

Which is kind of an insane concept to me. lol

[undone anvil]

I guess it could be one of those cores where you fetch the bios yourself.

[lyric dagger]

It could, yep. For most cores, I have to be sure not to include the ROM directly on the git repo anyway.

I mean, I get that you have copyright on things like books, to prevent plagiarism etc.

But I think it's something that's a lot harder to enforce with code.

Especially if said code gets compiled into a slightly more esoteric or encrypted format.

When I put my code out there on github (as rough as some of it is. lol), I don't think I've even included a license for most of them, unless it was part of the original README (EDIT: from a forked project).

I just assume that anyone will be able to use that code for something. The only thing I ever asked in the past, is to please give a small credit if a larger chunk of my code / project helped you in yours.

[woven lava]

ah right - it has code that belongs to Cloanto and the owner of GEOS

that's the thing - if you make a new FPGA project/port that does not distribute the bios, and then people download the github code for the X16 and compile it themselves... technically the port is not at fault

[fleet cave]

the real fun thing for them is if all that code is compiled into a single rom 'blob' they may have just created GPL licensed copies of GEOS and whatever Colanto owns

but the only way that would be resolved is by you catching a lawsuit if you used it

[woven lava]

which nobody wants, so best to stay away

[elder cove]

Is the Mega65 in a similar boat? I saw that one also had source code available

[lunar trellis]

I think this was talked about awhile back, is this project open source? I have a feeling it may be closed

Ah I see catching up that yeah, it isn't open

[hollow estuary]

Source is available but is made up of various licenses https://github.com/commanderx16/x16-rom/blob/master/LICENSE.md

[fleet cave]

oh I see

[lunar trellis]

Licences that mean a core couldn't be done?

[fleet cave]

a core can be done

but the bios cannot be used with it

the problem is there's an active product using it

so putting it into even something like update_all is probably riskier

oh hmm

[hollow estuary]

The X16 project has a license to use this code in the context of the X16 computer. If you want to use these components outside of the context of the X16, please contaxt Cloanto (KERNAL and BASIC) and Click Here Software (GEOS) for details.
Sounds like its not completely impossible but I wouldn't hold my breathe

[fleet cave]

there's a gplv3 component but it isn't part of the default build

I guess that's how they got away with not infecting it all with gplv3

[elder cove]

However, it is also freely available with their self-designed emulator. Meaning theoretically a MiSTer core would be OK?

[fleet cave]

no, they wrote the emu

therefore their license with those companies probably covers it

if YOU wanted to compile that rom and use it with a mister core you're probably ok, because it's not like Cloanto etc are going to come to your house looking for violations

but you can't distribute it

[hollow estuary]

lol was hoping to run the x16 emulator on the mister hps but get SDL_OpenAudioDevice failed: Audio subsystem is not initialized

Ooh, I can do -sound none but its hanging doing nothing

[lunar trellis]

Is it worth someone reaching out to the Devs and asking nicely how open they would be to a MiSTer core being developed? I.e. not rocking up and demanding they hand over things like a bellend would do...

[hollow estuary]

Sounds like ElectronAsh already did that? #1047332497492553799 message

Just my armchair assessment but to me It doesn't really sound like things need to be handed over, just that the BIOS is the sticking point and that an agreement with Cloanto and Click Media needs to be made so that it can be distributed for MiSTer users

[lunar trellis]

It does seem the BIOS is the issue. With this being an active project, and not some forty year old system, it would be rum to just chuck the BIOS in the BIOS DB and could cause a lot of drama

[hollow estuary]

Right, which is why I'm suggesting that an agreement with Cloanto and Click Media needs to be made

[fleet cave]

The KERNAL code is not available as open source, nor will it be, due to licensing issues. Commodore's KERNAL is owned by Cloanto corp, and this is not likely to change. So you may not use the Commander X16 ROM without purchasing a Commander X16 Microcomputer.

There are discussions of creating a fully open-source KERNAL for the Gen-2 gaming system. This discussion is ongoing, and we will update this FAQ if this changes.```

[hollow estuary]

sad trombone

[fleet cave]

note: all parties involved know people are using the emulator without purchasing the hardware, but they're just opting to look the other way

[hollow estuary]

Wonder if the open mega65 kernal would work lol https://github.com/MEGA65/open-roms (note I have no idea how functional this project is)

[fleet cave]

mayyyybe

you still need BASIC tho, right?

[hollow estuary]

Yeah

[fleet cave]

or does mega65 include it too?

[hollow estuary]

There's a directory for it https://github.com/MEGA65/open-roms/tree/master/src/basic

So sounds like the last commerical component in the ROM is GEOS

Oh here we go, reverse engineered GEOS https://github.com/mist64/geos

[fleet cave]

you can probably build a rom.bin with all this stuff and have at least something that works

if it falls over in some places due to incompatability oh well. user can go violate licenses themselves if they care

[lunar trellis]

A console rather than a computer, but Game Tank core would be possible and the dude that made it was even on here a few years back saying he would love to see a MiSTer core and would help anyone working on one

https://gametank.zone/

[sweet scarab]

I'd love to see a GameTank an X16 core. I get the legal gray area, but none of the consoles come with bios. Really I see no difference from a core release standpoint. It's trivial to obtain the bios rom and could be left up to the user to 'acquire' it. We're all spoiled (thankfully) by update all, but I (if I had the skills) wouldn't let this stand in the way of the core. Just my opinion, no one is obligated to work on it. Just would enthusiastically support it.

Would be very simple to script retrieval of the rom from the emu releases. Or if you wanted to go hard mode you could script building it, but that seems overkill. And in any case, I'm not a lawyer, but since it would only be used for x16, it seems to be in the 'context' of that legal blurb Zakk wrote about earlier.

[fleet cave]

no, they specifically say in their faq you must purchase x16 hardware for the rom license

[sweet scarab]

ah, I missed that part

[lunar trellis]

I guess someone is making money selling x16 consoles

[woven lava]

that game tank looks pretty fun, a core would be nice

it has no licensing issues right?

there's also an open source Pico-8 emulator. That might be uses as the basis for an FPGA core

[lunar trellis]

Game Tank shouldn't have any issues, the guy who wrote it was well up for someone making a core for it and helping how he could. No takers as yet though.

[kindred wing]

Thank you very much for this! As a big Win3x fan this is exactly what I wanted to go digging for. I'll give it a shot once I have the time and create myself a small collection of Win3x games. If it grows and I'm satisfied with it, I might put it on some unknown "archive site" so it co-exists with projects like 0MHz and AmigaVision. 🙂
I was also planning on expanding upon the 0MHz collection, adding more DOS games.
Too much things to do with too little time. Life is hard. ^^

(@exotic prairie brought me here)

[robust monolith]

okay, we'll all "buy" the rom then. Be nice to see something like this or the M65, but if it's not to be, fair enough. We can't complain with the tons of stuff we've already got! Many thanks. 🙂

[round token]

To finish the story, the game IS in amigavision under that name. Obviously in C. (And I indeed feel it is better then the sharp version 😅)

[elder cove]

Going to work on getting some new packs together this weekend.

Got a fascinating puzzle game, some more forgotten point-and-click adventures, a PC trivia title that launched a decades-long franchise, and a children’s sports classic - keep an eye out!

[young gust]

Sounds awesome

Especially point n click adventures!

[mild oriole]

I’ve been wanting to play the original Metal Gear and Metal Gear 2 games on the MSX core but have a few questions

Is the disk based version of the game the one I should be playing?

In the core I can only map a controller for two buttons. Is there anyway to use a controller with the core for these two games or do I need to use a keyboard?

How do I save in these games?

[storm marlin]

No, the games were originally on cartridge and there was no official disk release.

The MSX joypad port only supports a dpad and 2 buttons, Metal Gear 1 and 2 expect the player to have a keyboard nearby to open the menus or save/load. this was because the keyboard is literally built into all MSX computers.

Metal Gear 1 can save if you use the Konami Game Master cartridge in the primary slot and Metal gear in the secondary slot, it works kinda like a savestate. More info on how to do that here:

https://www.msxblue.com/manual/gamemaster2_c.htm#:~:text=When you are in Pause mode%2C press on Left CTRL,the specific used MSX machine.

For Metal Gear 2, there is no need to use the Konami Game Master cartridge

You can simply save with F5 I believe? I’ll have to double check but it’s definitely one of the F keys

[storm marlin]

oh, forgot to mention but Metal Gear 1 + Game Master or Metal Gear 2 both save to floppy disk

you'll need to create some blank disks for saves

virtual floppy disks, that is

[summer dragon]

You can remap keyboard buttons to controllers as well. Not sure how many extra buttons those games need.

[storm marlin]

oh nice, I didn't know that

usually F1, F2, F3, and F4 are the important buttons

for Metal Gear 1 and 2 anyway

[elder cove]

Something that I’ll mention, as I saw this come up in the other thread.

All packs using this structure based on the ao486 core fall under the 0MHz project - that includes DOS, Windows 3.1, Windows 95/98, other x86 OS games/software, and PC Booter titles. There are around 100 Windows 3.1 packs and about 20 Windows 95 packs which are currently assembled as part of 0MHz.

This is for multiple reasons. Not only are the configuration standards on the .mgl side almost identical between all of these various platforms, there was significant crossover in software consistently between the main three (DOS, Windows 3.1, and Windows 9x). The only reason we don’t just choose to run almost everything in 95 is because of performance reasons on our end - and that seems like a silly reason to divide up the entire PC ecosystem. There are even cases where running a traditionally DOS game under 3.1 or 95 produces better performance or fixes a game which otherwise has issues on the core - Return to Zork being a key example.

As such, it all is placed under the 0MHz project banner, with the .mgl file placed in a directory of the intended OS of the game executables - ie. _DOS Games, _Win 3.1 Games, or _Win 95 Games. (This will be overhauled more significantly once @summer dragon and I finish the Community Pack, which puts together all the currently assembled secondary packs alongside sorting the .mgls by categories like Publisher and Series in the folder structure. Once that gets together, I’ll also put together a package called the Playground Pack which provides reference configs for some of the more recent Win95, DOS Booter, and FPU emulation packages, along with a document I’ve been working on which goes deeper into the format, the folder structure, and how to use CPU/drive automation from DOS.)

[kindred wing]

Wait, so you (and/or someone else) is already working on Win stuff? That's neat! 🤩

[lunar trellis]

I had a thought, but I imagine people must have tried this already. Could someone make a 0mhz for something like winamp or another music player, and have it set up to point to a music folder on the SD, and it be able to play music on the MiSTer?

[fast kraken]

you could do something like that with misterFS iirc

[elder cove]

It should be possible with misterFS’s shared directory, yeah.

On this class of a 486, I don’t know if it would be fast enough to play without stuttering, though. I’ll do some tests with WinAmp and WinPlay3, see how they run.

[lunar trellis]

What is misterFS?

[hollow estuary]

https://www.jamesfmackenzie.com/2021/02/14/mister-ao486-core-part-2-transferring-files-with-misterfs/

[summer dragon]

I know Dave linked it above, but its a little app that lets your DOS drive see the shared folder in games/ao486 as an available drive. convenient for transferring/reading smaller files

[hollow ridge]

I fixed some issues with ROM loading and reset, and it unexpectedly helped a lot with Fmax. I was able to nearly double the Uxn CPU clock speed, while still meeting timing!

Bunnymark score is much improved! 850 sprites at 60fps 🐰 It draws the Mandelbrot in record time now!

[elder cove]

Out of curiosity, has anyone gotten Rhapsody running on ao486?

For those unaware, Rhapsody was a prototype x86 Apple OS from the 1990s. I tried loading it on the core, but I hit a kernel panic shortly after getting into the OS installer.

[hollow ice]

I think openstep is close- problem there is the ide issue.

[void belfry]

yup...

[elder cove]

The Evryware Space Collection is going up:

This includes Space Dude and SpaceKids, two wild and surreal action games with a distinctive "Mode 7"-esque aesthetic.

[elder cove]

Endorfun is going up:

This is one of those games where I forgot how much I enjoyed it. Once you get into Endorfun, it becomes a surprisingly addictive little puzzle game.

[thick pendant]

As long as you don't mind 8.3 filenames...

[thick pendant]

Based on performance of the DOS based MP3 players I've tried, its not going to work unless you convert to an extrememly low bitrate.

I also seem to recall MisterFS not working well with Win95.

[copper slate]

BRUH

I HAD THAT GAME

[elder cove]

The Crystal Skull is going up:

[void belfry]

In that regards, Minimig core is better, it can play MP3s (admittedly at 22kHz bitrate iirc)

[summer dragon]

I’ve definitely used it with Win95 before. I think I transferred a file to a VHD and it was slooooooow

[void belfry]

As well it won't work under NT (but if you installed it on a FAT partition, not NTFS, you can boot in DOS mode and use it there)

[hollow ridge]

Finally got to try the core on a CRT, after switching from the Digital IO board and back to Analog IO for now.

It’s working, but isn’t quite right yet. I might need to check what other cores are doing differently. Even the menu is squished horizontally when I bring it up while in the core.

This little 5” PVM is so cool though 🙂

[summer dragon]

anyone here that’s completed Lionheart on the Amiga core?

I’m told by a friend that tried to play it that the game would crash randomly on both MiSTer via Amigavision and in PC emulators 🤔

[elder cove]

No, I haven’t - if it’s happening under both emulation and on the MiSTer, my guess would be that it’s an issue with the WHDLoad config.

[exotic prairie]

Maybe check with Limi too

[elder cove]

So, one of the more ambitious projects I’ve been taking on recently for these 0MHz packs is a incredibly ‘90s point-and-click adventure called Skyborg: Into the Vortex.

Skyborg, when it released, was a project created by the card company Skybox to highlight a collection of independent sci-fi and fantasy artists, with the game written around the card designs (which were all original paintings from the art collections of Dave Dorman, Julie Bell, Dave McKean, Brian Stelfreeze, and Gerald Brom).

The cards play a pretty significant role in the game, however they’ve never been scanned in particularly good quality. So, I bought an entire case of these cards, with the goal of essentially putting together as complete of a set as possible and digitizing them to be accessible via the MiSTer Help menu as .PDFs during gameplay.

There are essentially two sets to each collection of panels - a front side, which features each individual character, and a back side, which is a 9-panel display design:

The front sides feature metallic text at the bottom, however, which mean they actively do not scan well on a bed scanner and the colors will look dulled if you process them that way:

That means that I essentially need to photo every card at an angle like this using a phone camera so that it gets the highlight like this, then de-skew them using Lens and color correct them using Photoshop based on the original card.

[hollow ice]

admit it, you are just using the mister as an excuse to collect really cool old games 😀

[elder cove]

Oh, pretty much lol

[summer dragon]

you’re doing some serious preservation work here. It’s awesome to see!

NetManage Chameleon Xoftware for NT 4.0 on ao486 running X apps from my spare Raspberry PI via the PPP connection 😉 (got inspiration from CRD's vid https://www.youtube.com/watch?v=XHGKKdyU2bE)

[feral shore]

mind blown

[void belfry]

next stop is Amiga core 😄 will see that after work lol

[void belfry]

there's some Xami package, will test that on the double PPP (230400 baud) core. And hardly wait what this is going to https://misterfpga.org/viewtopic.php?p=98392#p98392 👀

[void belfry]

Also came across this DOS software https://www.vogons.org/viewtopic.php?t=79490 ... anyone around heard of this Xappeal ?

[robust monolith]

Only one way to find out - http://ftp.lanet.lv/ftp/mirror/x2ftp/msdos/programming/xwindow/00index.html

[void belfry]

lol, i meant if anyone used it back then

i remember trying some time ago also Desqview/X on ao486, but to no success at that time

[tulip atlas]

I played through it using the .adf disks and an Amiga 500 config with 512k chip mem and 2MB fast mem. I disabled slow mem because it causes gfx glitches in later levels.

https://github.com/MiSTer-devel/Minimig-AGA_MiSTer/issues/87

Great game and not too difficult.

[robust monolith]

desqview, wasn't it like a multitasking os thing? One for google methinks.

[summer dragon]

awesome! I’m going to play it as far as I can in Amigavision for science so I can report the crashing bug if I hit it, but this will be my backup plan! Thank you!

[hollow ridge]

Some more CRT videos of the Varvara / Uxn core. It just looks so cool this way, if a little eye-straining 😅 I bumped the resolution to 512x240, but I might try to add a toggle for a 256x240 mode so that it’s easier on the eyes for small screens like this

[summer dragon]

yep, Lionheart crashed for me in Amigavision 😅 https://whdload.de/mantis/view.php?id=6759

seems likely that it could just be a typo somewhere causing the error, so hopefully it can be fixed fairly easily 🤞

[feral shore]

@void belfry hey have you had an issue where win98 just hangs after install? after the bios printout there's just nothing, basically the "starting msdos" or equivalent message never shows

[void belfry]

not that i remember

[feral shore]

thanks. I may have an odd problem but it's outside the scope of ao486

just figured I'd ask

[spice hound]

When are we getting apple //gs core?

[grim lodge]

Is the suck and blow machine in banjo tooie a reference to the amstrad?

[undone anvil]

oh that would be great. haven't heard anything about it in a while

[spice hound]

If nothing happens I will be forced to get an apple //gs. not that I mind heheh

[undone anvil]

go for it, I've heard talks about it years back, who knows when it will come

[silver inlet]

My family had a ][gs when I was growing up. Definitely the core I wish for most now that Saturn is locked down.

[lunar trellis]

What chips are we missing for a GS? I know Alan and Pierco did some work on a core awhile back

[elder cove]

Not sure - probably makes sense to move discussion about the IIgs to the #1269857027077705729 section, though

[wise drum]

Mostly the ensoniq audio probably. I would think the rest could be done with 65816 from the SNES core and the current Apple core, but what do I know. Dev has to be interested

[vestal isle]

@void belfry, I found a way to run a bunch of new-old OS's under AO486! I've tested this method and it works for the following systems: DG Nova, VAX, SWTP, VAX780, pdp8, pdp11, id32, hp2100, altair, and altair z80! https://virtuallyfun.com/2009/03/11/new-ms-dos-build-of-simh-3-8-1/

Haha

That is wonderful

[void belfry]

Nice, gotta play around with it over this weekend 🍻

[clear wing]

Hi guys, I recently picked up an NEC multisync VGA CRT monitor to use with my MiSTer, primarily with the computer cores. I have a MiSTer pi with the MiSTer pi analog board. I got it working well with the arcade and console cores by forcing scan Doubler but I'm having a hard time getting ao486 and x6000 to work. What is the best way to get true 31khz video output for these cores?

[gloomy bolt]

There's a whole CRT setup wiki pinned in #settings-workshop

See if that has the answers you need. If not, that channel is the best place to ask.

[granite umbra]

[elder cove]

Probably won’t be doing any packs this weekend - going to help work on the translation for a previously lost Osamu Sato game, Rolypolys 2 World Tour. (Hopefully should run well on the core once it’s together.)

[young gust]

Nice!

If you get a chance, take a look at the DOS game After Life. I haven't been able to get that one to run. Not sure if it's beyond the abilities of the core or not.

[woven lava]

that was a fun game

[elder cove]

I’ll take a look at it. I seem to remember that Afterlife has always been a bit finicky, even on original hardware - I’d also be curious to see if the Windows version runs, though.

[storm marlin]

That was such a good video

[waxen brook]

Never heard of that one! Sounds pretty unique, would love to try it. Thanks for your work

[waxen brook]

Just finished it today. Almost bought the sorcerian soundtrack cd's after watching, but the prices were too damn high and I located some FLACs instead.
It was the first Falcom game I played, the DOS version. Not a great game, but captivated me for a long time when I was a kid, trying to discover the path through those dungeons and all the hidden items.

Got an install working for Afterlife under Win95 - seems to work well, though scrolling is a bit slow.

[young gust]

You're amazing

[gloomy bolt]

Such a fun game. It was one of the first things I installed on the core... I did the whole Lucasfilm/arts shebang up to MI3. Which "works" in an academic sense, but isn't fun to play on the core.

[silver inlet]

If Ao486 was just a tiny bit faster it would unlock so many great late 90s 2D PC games.

[terse totem]

Minimig is pretty nice, but also the soft core leaves things to be desired

I'm playing with adding an ethernet bridge.

Not the most performant way

[shy imp]

minimig seems very interesting

faster CPUs in ao486 is a wonderful dream though...

[hollow ice]

Good luck. Would love to see ne2000 in more cores.

[terse totem]

I figured that bridging the ethernet as ne2k to the cores would be the lowest common denominator

I was compiling the kernel modules last night, and insmod was not happy with the .ko files that I've built, so little steps

[inland sinew]

What be the name of that MiSTer Sharp X68000 project that sets up games like the 0MHz collection?

Neon X68k. Found it lol

[summer dragon]

yep, Neon68K

[inland sinew]

Seems like they changed up their file structure recently

[summer dragon]

no, nothing has changed since the initial release

that said, I think there will be some slight changes there in the next release

[feral dagger]

Oh wow

I didn't know that collection exists. Thank you very much, il look at setting that up. I really enjoy all these computer pre made collections

[exotic prairie]

@granite umbra Did we ever determine if Rebel’s revert to have sprites load properly is going to be merged? It sounded like there were too many regressions but I wasn’t sure if there was a decision about whether or not it should be merged

as soon as work calms down, I want to look at D88s and see if we can add some more game

[granite umbra]

The speed regressions has to be address before the merge I think.

[fast kraken]

wow cool i remember tripping over that lemmings2 thing when we were making top300. honestly thought it was the game. i love how ao486 keeps improving over the years no matter how slowly

[inland sinew]

PCN's video shows a 400MB download. Current NeonX68k is like 3 gigs. I think it's changed.

[summer dragon]

Well, that’s odd. The only thing I can think is that the files might have still been uploading when he shot that video or it was an archive quirk, because the pack was never that small. (source: I’m the one that uploaded it 😉)

[exotic prairie]

PCN found the old pack (before the real version went live)

[inland sinew]

Oh. Thanks for your contributions!

[young gust]

Started playing the 0mhz game Albion. Unfortunately it constantly crashes in the first person dungeon crawler segments 😦

[young gust]

Gonna try it with the latest unstable that just dropped and see if that improves anything for it

[elder cove]

You know, the one I’ve regularly encountered a hard crash on in a 0MHz pack is I.M. Meen. As soon as I get hit by an enemy, the whole game locks up.

I don’t know if I ever asked, but has anyone else encountered that issue with the game? (I haven’t tested the latest unstable yet, but it’s been doing that since at least the 12.27.24 release.)

[uneven cliff]

@summer dragon will that be near term, or something months out? I haven't downloaded yet, just curious if I should or wait

[exotic prairie]

it's a while out. once the decision is made on the core changes (and if they should be committed), I'll run through the games in the pack and adjust compatability. We will probably do a release then. Then I'll start lookin at D88s to add games

there won't be a pack with new games for months - but there may be a pack with the games restructured in it in a month or two

[uneven cliff]

Roger that, downloading tonight then. Thanks for the hard work!

[exotic prairie]

also https://github.com/Neon68K/Automatic-Updater-Script

However, as the person who help ChatGPT write that script, I'm not sure I can recommend it. It definitely works :p

but I haven't had anyone who actually knows what they are doing give it the ok

it's just me and chatgpt

sitting in a tree

[terse totem]

Lol, Claude AI seems more OCD than Chat GPT.

I've just used it to add comments to joystick and mouse/keyboard handling code on ao486, pretty cool. It was able to also pick up some issues in these files. I guess, it's to be confirmed.

[young gust]

Stupid question time

I downloaded the latest unstable ao486 build. I slapped it in computer core folder. Ran update all for other reasons and it redownloaded the 12/27 core again. So which core would the 0mhz games go-to to run? Should I just delete the one update all redownloaded?

[summer dragon]

it’s a good question…when you have two cores with different timestamps in the filename, I’m not sure what core get picked to run when launching with MRAs. I would say just delete the one update_all downloaded and maybe add a filter to downloader.ini if you don’t want it to redownload it

[young gust]

Thanks. I'll do that. So far Albion has been running for 45 minutes in a dungeon with zero crashes.

[elder cove]

I just tested, and the crash in I.M. Meen still occurs, even on the new build.

[tulip atlas]

I used DiagROM v2 (https://www.diagrom.com) on Minimig 250609 unstable (after TOD fix was implemented), and I got failed CIA-B TOD Hsync:

On stable minimig 250119, no such error:

No clue if it means anything.

[hollow ice]

pal or ntsc?

[tulip atlas]

PAL

[hollow ice]

I seem to remember a long time ago that my ntsc amiga would fail some of the timing checks, but that was like 2018ish timeframe

[tulip atlas]

It seems the CIA-B number varies slightly when repeating tests, but always passes on old core, fails on unstable new core.

Probably means nothing...

[hollow ice]

not sure. That seems like a pretty significant decrease in ticks

[north dove]

Ah, nice to know I can add filters in downloader.ini. I have a list of arcades that I don't want update_all to download.

[terse totem]

Try amigatestkit, it has probably better checks for cia timers than diagrom

Also, the vblank is off

Some updates of PET2001 (not propose for the moment on MiSTer Devel)

[hollow ice]

There are quite a bit queued up from Rhialto on the mega65 side of things to bring in newer 80 column pets and a wider variety.

that's just code comments to joystick and ps2 files

[fast kraken]

oh that was yesterday heh

[terse totem]

oh, you meant those 🙂

[fast kraken]

meant to help with lemmings, idk if anything else is worth retesting

[granite umbra]

@tulip atlas and @terse totem a new version to test from tdelage26
https://github.com/MiSTer-devel/Minimig-AGA_MiSTer/issues/193#issuecomment-2960467280

[terse totem]

I get the same numbers in ATK as I previously posted, so the VBlank and CIAB TOD is off

10 ticks less than expected on CIAB TOD

And VBlank frequency is 50.07 vs 49.92

ATK shows the same numbers for the January rbf, so if it fixes some game, then it's great

[wet hound]

Yeah i have the same results too. Anyway all the tests pass and are within the ballpark so it's perfectly acceptable. Moreover are minimig CIA timings supposed to be exactly matching the ones from the original Amiga ? I though no as far as the only thing cycle accurate in this core is the 68000 CPU (using the FX68K core) 🤔

[terse totem]

CIAs are not dependent on the 68k cycles

http://amigadev.elowar.com/read/ADCD_2.1/Hardware_Manual_guide/node012E.html

[wet hound]

I never said CIA were dependent on the 68k cycles. I just said that the only component being cycle accurate in the minimig core was the 68000 CPU. All the other chips (including the CIAs) are supposed to have timings in the ballpark of the real hardware but not an exact match. That's why the demo "voyage" by Razor 1911 (the adf disk version) is not booting on MiSTer cause the protected loader used in that demo relies on the accuracy of the CPU/bus timings as well as the CIA timings that need to be 100% accurate to properly boot which minimig is unable to provide.

[terse totem]

Fx68k soft core is supposed to be cycle accurate

[thick pendant]

this Amiga 1200 gets different results:

[terse totem]

1 tick off on CIAB TOD

[thick pendant]

my A1200 is out of spec 😦

maybe PiStorm is doing that

[terse totem]

I have a z3660 on my A4kD.

[thick pendant]

nice, is it fast?

[terse totem]

With 060@100?

[thick pendant]

I was using a Blizzard 1260 with Rev 1 060

PiStorm32 is nice because it brings faster storage and RTG

[terse totem]

Yeah, PiStorm rocks

[thick pendant]

My Blizzard SCSI board burned up when I tried to attach a SD card SCSI thing.

so I got sad and put the A1200 back in its box for like 6 years.

but now I have PiStorm and a nice mechanical KB https://amigastore.eu/en/994-mechanical-keyboard-amiga-1200.html

and I got one for my MiSTer A1200 as well

but not installed yet

one has blue switches and one has brown(i think)

[terse totem]

This is from FPGAArcade Replay with 060 DaughterBoard

I guess, it doesn't matter

[thick pendant]

I tested minimig CIA TOD with DiagROM v2 again, this time without slow mem. I think slow mem messed up my previous results. Without slow mem, all is fine in all versions!
Unstable 250607 no slow mem (left)
Unstable 250609 no slow mem (middle)
Stable 250119 no slow mem (right)
