programmed in C

#

so much of the MD's power is squandered on processing the bulky ass code

#

it's because of all the speed loops in the game hah hah hah

#

ah, seeing you reminded me to check to see if SAM and your remote script together yet

#

together?

selecting a game with the remote didn't stop the SAM kicking in and taking over

lol true, the Genesis core’s turbo mode would solve that one

Just curious if anyone's experienced a pink overlay with using Direct Video, component, and this core specifically? Every other core displays correctly.

#

It's only when a game is loaded, regardless of the game.

#

Messing with the Scandoubler Fx function restores colors, then reverts back with them all off, so I'm guessing it's something to do with the 320 x 224 mode. It causes different issues on my CRT when using original hardware so maybe that's where the issue is? Maybe it's already known about.

#

I haven't had the chance to check the Github yet, but if it's a new issue I can submit an issue there.

I seem to recall seeing that it's a known issue

Gotcha, good to know.

Hey guys. I finally figured out that issue with the 4-Way player 4 inputs not working on the new core. Apparently, if you set the controller type to 6 buttons, player 4's inputs don't work with the 4-Way multitap with select games. However, they do work on the Genesis core with 6 button controllers selected and the 4-Way multitap selected. Does anyone think this is a quirk on real hardware or a glitch on the new core?

manic ridge
#

Good question because if it's not present in real hardware sounds like it needs to be mentioned on github

compact plover
#

It's really not a big deal considering that I cross-checked the list of 6-button compatible games and none of them use the 4-Way multitap. It's just a slight inconvenience to check two more boxes before firing up a 4P session of NBA Live 95 for example

manic ridge
#

So is the pink output over analog not a bug?

Hi. Anyone knows if the logic analyzer tracelogs stored in MCD repository (https://github.com/MiSTer-devel/MegaCD_MiSTer/tree/master/docs/mcd logs) are coming from real Mega CD hardware captures or if they are captures from Mister FPGA MCD core ? I am asking as Blastem author had some doubts about their source, considering it looked more like Altera/Intel SignalTap output to him.

It is signaltap, it's most likely the core, however you can use the DE10-Nano as a logic analyzer and hook signals to probes and analyze them that way if you wanted to as well. So I'm not 100% sure. Srg320 who made that core also has used the DE10-Nano as a logic analyzer in a few cores.

Anyone have any experience using cheats on the nuked core?

#

Was playing sonic with the gf and I wanted to give her infinite lives. There were two options one for 99 continues and another for infinite. Ones game@genie the other was something else I forget. Both exhibited the same issue. Screen turns red and sits there. If you restart the core and enter game you don’t get the extra lives

glass shale
#

Red screen means bad checksum

#

Probably core needs to update checksum after applying cheats?

#

Are cheats applied to rom and not ram? 🤔

#

I’ll update and give it a shot later tonight

#

Seems like this will eventually be an excellent candidate for replacing the existing Master System core, just like with the Mega Drive/Genesis.

old sierra
#

Oh nice, great to see this one progressing already. Is there any rough estimate when a core could be completed that could then be ported to MiSTer like the current Megadrive? SMS is definitely a system that could benefit from the attention that Megadrive is currently getting.

SMS?!?! Is this from decaps too? Very excited to keep on eye on this one

I'm hopeful this will result in a YM2413 that finally sounds right outside of the real chip.

#

I have been thoroughly unimpressed with hardware and software clones of this thing to date.

Although they have some head start thanks to their mega drive core

pale plover
#

I'm guessing Game Gear will also get attention due to the similarities to the Master System?

old sierra
#

I was wondering about that, would that benefit from a Nuked effort also?

I was wondering how'd Nuked SMS benefit but then @Ace mentioned the YM2413 possible getting to sound more accurate

If you got the bios from bios getter then it should work

Yeah, i got the bios from the bios getter from update all, is the only game that i have that I can't play.

I'm going to try another image, and see.

Yeah, that's helpful to know. If it's the only game that will not play, it's most likely that game.

I also did some tests a couple of years back now with some test roms on the core and it failed a couple, here are the tickets for those:
https://github.com/MiSTer-devel/SMS_MiSTer/issues/112
https://github.com/MiSTer-devel/SMS_MiSTer/issues/113

So there are definitely also some accuracy improvements that could be made, as well as a reason for someone like Sorg to also get some extra features and functionality in there like BIOS loading and keyboard support etc.

I did which we discussed a couple of weeks back I think here, and turns out these test roms don't work on Mega Drive hardware only SMS, so fail on both and aren't usable

If we get a nuked Master System core another benefit would be perfect backward compatibility with the SG-1000. As of right now, SG-1000 support isn’t perfect on either the SMS or Coleco cores

pale plover
#

Personally I think they should just cut out the middleman entirely and make the SG-1000 core from scratch.

1000% yes

You need a Japanese BIOS to boot Japanese Mega-CD games. That's a picture of the PAL or US BIOS CD player.

pine crystal
#

Yes. Either that, or try to source a region-free BIOS.

carmine pine
carmine pine
carmine pine
# red sleet yeah, in its own folder:
  1. Is it in a folder or is it in a zip archive? it needs to be unzipped
  2. Are you using the Japanese bios? If so, what is the MD5 hash of it? Mine is 683A8A9E273662561172468DFA2858EB and it works. If you use a different bios for different regions, you need to rename it cd_bios.com and put it in the same subfolder. I just tested with the bios that comes from update-all and it behaves the same as yours. You have to use the Japanese rom for this game.
#

683A8A9E273662561172468DFA2858EB <-- works (japanese bios)
854B9150240A198070150E4566AE1290 <-- doesn't work (normal us bios from update-all)

#

this is how i handle the japanese bios, i put cd_bios in a Japan folder so every game in that folder will load with the japanese bios instead of the one a folder up one level that is named boot.rom

X'Eye... I have mixed feelings about this thing.

merry spade

it had the best audio you could get out of a SegaCD.

tidal python

I can't agree with that at all.

fallow dome
#

I agree with that statement only because I want to cause trouble and not because I have any idea what I’m talking about

pine crystal
#

Valid

tidal python
#

JVC designed an overly convoluted audio circuit for the X'Eye, and yet, the end result is really underwhelming.

#

The one thing it does well is handle games with overly loud sound like Shadow of the Beast.

So when do we all grab the broken beer bottles and have at it?

I always thought it was an interesting model. I wouldn't mind having one to add to the collection, of course.

It was a novel idea, but neither Sega nor JVC did a good job for sound. JVC still did better than Sega, all things considered.

I have concerns regarding the validity of this statement. 😉

My MDFourier plots and audio samples are a scattered clusterf* after dumbass me hot-swapped a hard drive and SSD, and managed to corrupt the partition table on the hard drive where the plots and samples are stored. The files were recovered, but the folder structure is completely broken, and I don't know what's what anymore.

Well then, I stand error-corrected. 🤣

That is cool!

If I find them, I'll post them, otherwise I'll make new samples and promptly mod my X'Eye to fix its audio deficiencies.

It would be better if I can recover the full folder structure of that corrupted drive... >.<

Sega is awesome

tidal python
#

What I can't understand from the CDX is why the headphone out is bass and treble-boosted so much.

fallow dome
#

Maybe because they thought kids would use it as a cd player?

#

if I had one as a kid that’s what I would do anyways, haha

pine crystal
#

Just wish I liked the Saturn more than I do (loving the progress on the core, don't get me wrong). That console never really impressed me from the very beginning. The only console released by Sega that disappointed me. The US library compared to Japan didn't help much. The Dreamcast made up for it though. I loved that... but never as much as the original Genesis and Sega CD. Those got the most playtime from me over the years.

tidal python
#

I think I'd have a problem with it because even when I was young, audio anomalies really stuck out to me.

pine crystal
#

I was in the Air Force when the CDX came out, and someone in the dorms got one and used it for music in his vehicle. Sounded good there. 😄

tidal python
#

I remember once suffering from an ear infection that really screwed up my hearing for a week or so. First, it sounded like I was always in a tunnel because everything sounded echoey, then my pitch perception got messed up.

#

Lower than normal, higher than normal, even once hearing at different pitches in each ear. Bleh.

#

"Made playing guitar... problematic." 😉

Maybe that was the reason for hearing what seemed like a perpetual echo. 🤔

Like a decade ago I had an ear infection that got progressively worse for like 2 months straight. I genuinely thought I was going to lose hearing in that ear (by the end I seriously couldn't hear much out of it). I remember I got very depressed thinking I'd never hear music or anything quite the same. It did eventually heal but, it's one of those things where I try to not take it for granted now. Glad yours also cleared up, it's scary stuff

# merry spade I used to have this. I miss it.

i still got one, it's a weird one. i don't have the branded controller though. the audio is really bad on these for the most part, but I found out that the factory sometimes bridged the left and right audio out of the din connector's output in the back, not sure why. i desoldered the wire hack they put in, and bam audio was a lot better, but still nto as good as a proper model 1 setup

#

the balance on mine for cd audio <-> rest of the audio is pretty poor. shining force cd you can barely hear the narrator in the intro

#

which is... notoriously a quiet game for cd audio

I've been having problems trying to get certain translation patches to work on the Mega Drive core.

I think it has problems with the "bilingual" patches used for games like Pulseman, Twinkle Tale, and Tougiou King Colossus. Other translation patches like for Star Cruiser, Madou Monogatari, Lord Monarch, etc. boot and run like normal.

I don't know if I'm just using the wrong programs or ROMs, which is why I want to double check it's not just me.

#

Pulseman always throws up the "DEVELOPED FOR USE ONLY WITH NTSC MEGA DRIVE SYSTEMS" screen, regardless of it being NTSC or PAL.

Gleylancer and Twinkle Tale throw up a bright red screen.

Other games just hang on a blank screen.

glass shale
#

Red screen means bad rom checksum so probably bad patching

#

As for pulseman try to disable tmss

night cape
#

USA region locked games have this text with NTSC Genesis text instead.

pale plover
#

The thing is the Pulseman hack is supposed to detect a NTSC-U console and switch over to English when it does so.

The bilingual patches work by detecting an NTSC-U or NTSC-J console, then changing the language to either English for the former or Japanese for the latter.

I think the core doesn't know how to interpret this, so it causes the games to fail to boot. Every patched game that failed to work are all the bilingual ones, not the straightforward "Japanese to English" patches.

#

So I decided to boot up the old core, and it's doing it there too. So maybe it's a bad checksum? Which is strange since the ROMs I'm working with aren't bad dumps, they came from the "No-Intro" packs.

night cape
#

Maybe it's not detecting correctly, causing the game region detection routine to default to japan.

simple apex
#

so I took the 'bilingual' pulseman patch from here https://www.romhacking.net/translations/1099/
and applied it to a clean Japanese pulseman rom, and it works just fine for me on the MegaDrive core. I can swap between JP and US and the game boots up fine and loads the proper text depending

ROMhacking.net
Pulseman

As seems to be standard practice with MIJET's work, the patch contains both the original Japane

#

I couldn't even get it to trigger the "only for use" screen at all, even switching to EU it didn't do it

pale plover
#

Okay so I can safely say it's not a problem with the core, patch, or ROM. For some reason my patching program just specifically hates those patches.

I was lazy and doing it on my Android tablet, so that might explain something.

night cape
#

So you were just running the unpatched japan game.

The emeralds don’t flash like this on a crt do they?

#

Wondering why it’s a thing

pine crystal
#

I believe so. That effect takes advantage of the natural phosphor decay of a CRT to create a more subtle shimmering/sparkling effect on an object that is supposed to appear transparent. That abrupt on/off flickering would not be nearly as harsh and obvious on a typical CRT.
It's somewhat similar to the behavior of a typical incandescent light bulb when you cut power to it. It's a gradual decrease of light output, not nearly as abrupt as an LED.

SMS or MD/Gen? I have an SMS light gun

#

And will gladly try it out.

#

But alas...never picked up a Gen lightgun.

cloud otter
#

The most recent unstable has a slight drift down for me. Here's the file you posted with me firing directly at the center of the boxes from 2 inches away. You can see how it starts to drift right on the right hand side. But latest unstable stays X axis centered, more or less, but drifts down on Y a little. If that makes sense. Again, this may all be for nothing and this isn't about the SMS phaser. If so, appologies.

carmine pine
#

Yeah it's only going to matter for the sms phaser for this testing. The user said it still didnt resolve the issue. I'm not convinced yet that this doesn't happen on original hardware. The delays in there are all from the chips as designed by nukey

#

Since it has a slight drift down that does probably confirm that it is going twice as slow then on response as I expected.

cloud otter
#

Actually, let me just capture from my Gen. real quick on the exact same setup since it's literally right next to it.

#

Nevermind. I forgot my composite capture card fried. But I'll take a look and report back (always better to have proof, though).

#

OK, OG model 1 v2 has a slight offset on the right side as well. Very slight. Like 30% of the cores, so it 'feels' on target from far away. Though your core does compared to the original SMS core as well. I guess that is important. Both the vanilla Nuke core and your changes both feel much better than the SMS core.

#

(And apart from name entry, nothing really happens at the edge of the screen in light gun games normally...they favor center).

carmine pine
#

yeah it's one of those things where even how new the tv is can influence it

#

the sms games were calculating it per scanline and then it would kinda get it in a rounded circle spot for where it is pointing. you have a little over 50 microseconds per scanline on ntsc, and the algorithms could be anywhere from 10 microseconds to over 30 microseconds delay depending on what method the game used

#

i think it' snot likely to be fixable since even the manual for the phaser says to stand basically 2 meters way from the screen, any more or less will influence the aim 😄

#

but if the screen is bigger than normal it could react differently, if the newer screens had a millisecond delay it would make a big difference, etc...

#

only seems to happen on a freshly turned on mister

hrm that doesn't make sense. whether it's freshly turned on or not shouldn't make a difference. where are your save files stored currently?

stuck gull
#

saves/megadrive

carmine pine
#

are you using mgl files?

#

if so increase the delay value in the mgl file, or try it without using an mgl file. i just tested with phantasy star iv and it worked normally loading the core and then loading a game

stuck gull
#

is that the recently loaded files?

#

bc yes

carmine pine
#

ah, yeah it seems like if a core loads and the game loads super fast the saves aren't loading right. this is happening with the n64 core too, didn't realize it would be happening in this too

#

try and reproduce by not using recently loaded files this time see if it works the same, just load the core, then load the rom

stuck gull
#

it seems to require a cold reboot to create the problem, if i just reload the rom the save pops up

carmine pine
#

i mean don't use the recently loaded

#

just do the cold reboot, load the core, load the rom

#

okay so i couldn't reproduce it with phantasy star iv but i coudl with s3+k

not even recently loaded... hrmm

that was super bizarre, doesn't make sense...

it's doing the same thing for me not using the recents also

okay it's not what i thought, it's likely something specific to sonic 3, i feel like i remember us having weird sonic 3 issues in the genesis core

#

ruled out it being something in Main just to be sure, it's definitely some kind of weird issue in the core

Yea I couldn’t reproduce in the older md core

#

well i noticed something probably incorrect in a couple places for handling save loads already, maybe i got it...

Was I just lucky somehow that my Sonic 3 saves just worked as expected?

I have got the 15th of September build of the Core and it works fine. My Saves appear as soon as I boot the game.

#

Also can I rename the Core back to being "Mega Drive"?

west sable
frigid tapir
#

@west sable is that in relation to me asking if I can rename the core?

#

If so... mine appears as this after some kind of recent update:

carmine pine
#

you probably have the region of your names.txt setup in the update-all settings ot north america or something

carmine pine
frigid tapir
#

Yes. That was me loading Sonic 3 from a cold boot. Straight into the Core, Selecting Sonic 3 (USA).

carmine pine
#

do you use a nas, hdd, sd card for game storage?

frigid tapir
#

RetroNAS

carmine pine
#

it was a real sensitive timing thing and it occurred on multiple releases back

#

yeah i use retronas as well

#

do you have tmss enabled?

frigid tapir
#

Yes I have TMSS Enabled too

#

Just for the fun of it 🙂

carmine pine
#

yeah i do too. hrm, either way i could reproduce it multiple times in a row and so could Shan. once I changed that it fixed it. before this update if you turned off autosave, when you pressed "Load Backup RAM" it wouldn't reset the game like it should. That would lead to problems eventually too. The sys_reset signal is tied to the cart-download, which means the bk_loading (backup ram load ready signal) probably wasn't happening at the right time, it was probably happening after the game loaded for some of us

#

and maybe only some games seemed to mind

#

the game load wouldn't reload upon regular reset of the game in the menu, so it would show back up. that's my working hypothesis anyways

frigid tapir
#

I have edited my names.txt file so it shows as MegaDrive for the Core 🙂 A small thing I know but I know it as the MegaDrive and grew up with it as that.

That's what the names.txt file is for, after all... customize it to your liking. 🙂

# carmine pine Which game are you trying? I can test later.

I was playing Shining Force, but I deleted the original Genesis core from my mister and was playing on an Analogue Pocket. Couldn't seem to get the saves to work when transfering them. So could be user error. Each time the Mister wouldn't read the file and would overwrite it and work fine after it had created its own save.

carmine pine
#

hrm, i'll test around. there shouldn't be any difference between them, but who knows.

carmine pine
#

did you symbolic link the megadrive core's saves folder?

graceful edge
#

I did not. I moved the saves myself using ftp

#

I probably just made a mistake. I’ll try it again and see if I can figure it out

carmine pine
#

if you moved them with filezilla then it's possible you have it on ascii mode instead of binary mode which would cause the file to arrive in the incorrect encoding

livid spire
#

With the old Genesis no longer a main core, what's the best procedure to swap games over now? Not needing a symlink I suppose.
Is a rename of "games", "saves" folders to megadrive enough?

versed rapids
#

Yes just renamed Genesis to MegaDrive for games/ and saves/ is enough
The symlink is usefull if you want to continue Genesis core

livid spire
#

Thanks! I'll probably swap and symlink to the old core then. TY

might as well just copy the saves folder in case you want to run the old core sometime

I wonder why Sonic 2 has that stray pixel line, but not Sonic 1, Sonic 3, or Sonic & Knuckles.

Especially weird because we know Sonic 2 recycled the engine used in Sonic 1, so you would think it would have the same quirk.

I think they just screwed up the scrolling for that particular level

I noticed those lines look normal at the start of each level, but once you start moving, this issue starts.

Worth noting the version of Sonic 2 on the Sonic Jam compilation does not have that stray line.

It was recompiled to run on the SEGA Saturn natively, which implies SEGA caught the bug and fixed it for that version.

@warm falcon maybe a quick question...

I'm reading the psg volume attenuation register stuff and comparing your software simulator vs the core. I see these floating point constants:

const float ympsg_vol[17] = {
    1.f, 0.772f, 0.622f, 0.485f, 0.382f, 0.29f, 0.229f, 0.174f, 0.132f, 0.096f, 0.072f, 0.051f, 0.034f, 0.019f, 0.009f, 0.f, -1.059f
};

and when you converted them to fixed point for use in HDL you did it by a factor of 1200. Why was 1200 chosen? I'm very new to this sort of thing so just curious.

warm falcon
#

Tuned max volume by ear, 1200 sounded good for me with my mixing code

carmine pine
#

Thank you! Wasn't really sure if that was a thing inferred from the decap or not 🙂

carmine pine
#

Just like Enforcer said I think the issue can only be truly resolved with the method that he helped Jotego with in jt89. Doing the equivalent of that for the nuked core is a bit over my head.

#

No matter how much I filter it will still be present so it's still just a bandaid.

#

I learned a lot very quickly through this attempt though so I'm not sad.

It legit feels like a professional TMNT game that I would have murdered a school yard full of other kids to play in the 90s.

#

OK, I finally finished smoke testing the 230ish unliscened games on the new Mega Drive core and checking against the old core that I checked a couple of years back. I can confirm there are 4 games you can play on the old core that do not boot on the new one:

Deer Hunter (R) (Unl).md
Harry Potter (R) (Unl).md
Iraq War 2003 (Unl).md
Pokemon Crazy Drummer (Unl).md

Which is pretty damned good.

OK, there we go:

glass shale

#

They maybe have some weird mapper

glass shale
#

If they work on the previous core then mapper should have been ported to the new one

west sable
#

Do Megadrive ROMs have headers? Id guess not, since .bin is binary

old sierra
#

It's a funny one, hopefully Sorg will know why and it's easy to add support.

frigid tapir
#

Pretty sure they do have Headers.

#

Soon I will find out. I am "acquiring" those games.

carmine pine
#

They didn't always follow it. For instance code masters games were unlicensed and so they didn't have the developer documentation so that's probably why they didn't always follow the header info correctly.

west sable
#

So is there a possbility that these hacky bootleg games just dont have the right header info and could be corrected to work?

carmine pine
#

The core doesn't really look for headers to adjust anything special like mapping other than region and some quirks based on specific per game product codes.

#

That's what sorg means though, if you have a huge list of 40 product code detections for a bunch of really subpar games that were unlicensed and made 15 years later, etc... it's not worth it to make the core complicated for that.

#

Each game specific quirk added takes up more resources and we are already constrained.

#

No one ever made an iNES or NES 2.0 equivalent for Genesis that I'm aware of. Emulators usually do per game quirks based on hash check

west sable
#

batty learns things every day

carmine pine
#

NES and atari2600 are fairly unique in this regard for special per game mappers. Most games just work with a Genesis emulator as is. Very few need special quirks. But unlicensed stuff, especially when they add special random chips on the cartridge, it can get hairy over time.

amber gulch
#

Hey gang, is the megadrive 23.09.15 core a straight upgrade to the genesis core?

carmine pine
#

It's a rewritten new core made from decaps of the chips

frigid tapir
#

Plus you can bet your bottom dollar of this.

Those Hacks / Unlicensed ROMS were NOT made with Real Hardware in mind. Certainly not judging by the dates some of them were being made / released. They were 100% being made for Emulators which can make allowances / bend the rules in certain ways.

I can always remember Sonic ROM Hacks working fine on 1 or 2 Emulators (like Picodrive which always felt very Hacky to me anyway) but when I ran them on my EverDrive Years Later on my Real MegaDrive, they didn't work. They would often Red Screen (Checksum error) or crash soon after loading up.

carmine pine
#

Nukeykt and his team pounded it out. It's extremely accurate.

frigid tapir
carmine pine
#

Many unlicensed roms were made for og hardware. Especially older ones that are from Asian countries.

#

But afaik, most of those work.

frigid tapir
#

Yep but some of those that have been listed in that GitHub Entry are from 2000 +. Like Iraq War is from 2003 onwards...

carmine pine
#

Yeah

amber gulch
#

So I take that as a yes in terms of accuracy. 😄

carmine pine
#

Yup

frigid tapir
#

By then, most would be using Emulators for reference I would imagine rather than a Real Mega Drive / Genesis.

#

That isn't my way of throwing shade at Emulators 🙂

BlastEm is highly regarded as very accurate. I am just aware of others (such as Picodrive to name 1) which I always questioned its accuracy.

amber gulch
#

To be fair, when I made a romhack of pokemon testing on real hardware was also the last thing I did. It's the most inconvenient thing to test. 😄

frigid tapir
carmine pine
#

Yeah it's not really a dig on those old roms. Early 2000s doing tests on og hardware with a custom rom was a bit harder than after we had everdrives and stuff.

old sierra
#

I did the Master System games as well, and updated the ticket, but looks like Sorg has weighed in there already. There's a lot more MS games where they boot fine on the MS core but you get a black screen and audio on the Nuked MD core

MiSTer is still emulation, it just has the benefit of parallel processing and lower-to-zero latency because the emulation method is FPGA. Nuked is (as I understand) cycle-accurate, the old code was not https://news.ycombinator.com/item?id=13052964#:~:text=A "cycle-accurate" emulator,tick of the master clock.

What does "cycle-accurate" mean? The README assumes the reader already knows; Wikipedia via Google is totally unhelpful: "A cycle-accurate simulator is a computer program that simulates a microarchitecture on a cycle-by-cycle basis."

Well, I don't know that I fixed it. I just removed the waiter, so it's probably going to introduce other issues for games that rely on the genesis to draw stuff fully before the 32X kicks in. I just kind of proved that disabling it reverts the old behavior.

Do you know the previous Genesis core will eventually be removed and won't be available as a second option?

pine crystal
#

There's a reason it's been archived in the repo.

carmine pine
#

Sorgelig will remove it when he feels it's time. There is not 1:1 feature parity so that might be why it's still pulling it.

limber pine
west sable
#

Just backup the old rbf, maybe keep it in the _Unstable folder

#

In case the script deletes it later

limber pine
#

Yeah, I have it there but I'm hoping this won't be like, completely removed from archives

#

Lost core on the internet

west sable
#

Hm.. maybe I should make a little section on my archive page for things like this.

errant bramble
#

Well it is a great core why remove it entirely ? It would make sense to have two alternative cores

Finally off set, so I took a glance at Knuckles Chaotix this evening. After digging a little...it appears (to my idiot dog brain) the MBUS_AS_N register isn't getting set correctly in the events of MBUS_NOT_USED and MBUS_FINISH states. It's 100% probable that I'm completely wrong...just tracing back the events. The core issue is the IF.sv line that checks for Genesis memory access. The failure was introduced when a check was added to that line in June. In the event it's 0 (megadrive memory bus busy), the SH code waits. Finishing in an error state looks like it doesn't release wait to the SH and neither does MBUS not used. All that said, however, with the original Gen core now archived, I don't know that work should be done until someone can pull the parts of the Nuke core needed to get 32X back into a supported state into the MiSTer-Devel branch.

I'm probably completely wrong about this, honestly. But for sure the check that kills KC is in IF.sv @ 838 (&& AS_N_SYNC[0]) ... so I'm surprised it was introduced in June ... If I had to guess...It's gonna be MAY! (that was stupid...I know).

#

However, setting USE_ROM_WAIT to 0 in S32X.sv or deleting the AS_N_SYNC[0] check in IF.sv both 'fix' the issue - but may introduce more.

cloud otter
#

This stuff is hard and I am now even more in awe of real core devs so much more than I have ever been. You folks are wizards.

#

@carmine pine did you ever mdfourier the new core? i searched but didn't see anything

glass shale
lavish sonnet
#

thank you!

#

i searched here and mdfourier server and saw nothing, was really confused

#

ok, so same old audio trickiness

carmine pine
#

yeah it needs a little tweaking to work with mister a little better due to downsampling

#

but it sounds good aside from one or two games currently, the differences aren't really that audible to anyone except ace 😛

lavish sonnet
#

@carmine pine the old core was just really, really good...although the Sound By JT ™️ always made me twitch a little

carmine pine
#

jotego's sound was about as perfect a recreation as you could get based on mdfourier plots

#

his cic filtering he added was part of the success

lavish sonnet
#

yeah it looks like you want to recreate that

carmine pine
#

it wreaks havoc on timing because of all the logic it takes and i don't understand how to calculate the stages/depth of the filtering based on the rate to get the proper linear gain for each channel as the end result

#

not enough knowhow

lavish sonnet
#

it's definitely my favorite thing that he has worked on, the twitch is because it was somebody else's reverse engineering but his initials...anyway, you know

carmine pine
#

i do know the rates of interp/decim that needs to happen to get it to even out, but that was like the easiest thing to do haha

lavish sonnet
#

dude that was a hell of a college try

carmine pine
#

well most work in this area somewhat rests on the shoulders of others

#

that's normal

lavish sonnet
#

its super tricky to take multiple and varying sample rates and make them work, or just rates in some cases

#

sometimes its just here's some analog output with an rc filter

carmine pine
#

the ringing problem won't be fixed by the cic filtering unfortunately. the filtering will just level off the higher frequency response in mdfourier

lavish sonnet
#

its funny how audio always ends up being some of the trickiest stuff

carmine pine
#

it's kinda crazy how complicated it can be lol

lavish sonnet
#

i am still hopeful there will be a gba test suite, there were a couple of niggles there that bugged me

#

on the other hand every single nintendo handheld sounds drastically different from one another and the gba core sounds better than any real handheld so whatever

yeah i use audio filters for the gba core. it's too crisp for my nostalgia hehe

Sorg took the 32X changes. So Chaotix should work soon.

west sable
#

Excellent!

manic ridge
#

How many bugs exist on that core now?

cloud otter
#

Well, the entire genesis subsystem is kind of a bug (it's built on old stuff that's no longer maintained). But there's a randomish freeze in Web of Fire I think.

#

Pinocchio has a hud glitch.

carmine pine
#

well the 32x core has a rewritten VDP and the bus arbiter was modified, as well as a lot of functionality taken out of the genesis core to help things fit and work well for 32x only

cloud otter
#

Yeah, exactly.

#

The work to get it retrofit is probably >>>> the value.

#

I'd wager more people boot it up to see if 'x bug is fixed' than to play it, too. Honestly.

#

It's also got some draw issues over HDMI. But overall, it's still pretty amazing it works at all, honestly. I play Star Wars Arcade every few months. It's got a few hits, for sure.

carmine pine
#

virtua racing is the game i keep coming back to it for, since it's the only game i had for the 32x when i had one

lavish sonnet
#

@carmine pine i am sort of surprised nukey's bus arbiter wasn't plopped into the old core

carmine pine
#

the vdp is better as well which is a big deal

#

that's the biggest chunk of code

#

that and 68k

lavish sonnet
#

it's just super modular because of how it was made

#

but i guess if features can be moved over whatever

New 32x build seems to have fixed knuckles chaotix

carmine pine
#

I'm pretty sure that sorg is correct here, only certain crts would show this. The user has a pvm (not Sony) and it's being strange.

#

Up close shots make it almost look like ringing.

weak zinc
carmine pine
#

the scanlines come up green though specifically when you zoom in

#

makes me think it's like blanking interval timing

#

maybe this screen is just more sensitive...

#

also it supports PAL colour freq over NTSC (PAL-M? PAL60?) so maybe it's getting misdetected by the screen

#

not sure lol

#

it's like something odd with SoG maybe? DE-15 output to RGBHV cable and using RGBS output from the mister.

#

this tv seems pretty nice

#

750 lines, lots of support for different connections and modes, etc... i gotta keep an eye out for this one in the future lol

weak zinc
#

Lemme try it on my JVC DTV

carmine pine
#

well the reason why i wondered about scoping it was because that core is using a 2x clk for the video clock

#

so it might be sending some green for longer than this tv likes during the blanking interval or something, or doubling it up during that time, etc... i looked for areas where the clk_sys clock was used instead of the CLK_VIDEO clock for anything video related and only found the switch for the new video mode, which shouldn't be relevant

weak zinc
#

But this should be a problem with anyone using the core

carmine pine
#

well it would be unless only some crt's are more sensitive to the blanking interval timing (assuming my guess is right)

#

there was a similar issue with the tmnt core early on

weak zinc
#

that was a different issue, everything with out of spec

carmine pine
#

i wonder if they just aren't using an external sync though

#

i dropped a message in there for them to troubleshoot more with some info on their monitor

#

but why would it be only this core...

weak zinc
#

exactly

carmine pine
#

so weird lol

weak zinc
#

and nobody else has the issue

#

?

carmine pine
#

not that i'm aware of, but who has this 1500 dollar rare tv 😄

#

reminds me of something Bob had to deal with a couple years ago, he was helping some guy from italy that had some ultra-rare tv and it was just hopeless, that tv just wasn't gonna work right with his signal chain

#

crt stuff is so crazy like this lol

weak zinc
#

I have a JVC DTV1900

#

its close enough

carmine pine
#

look at big spender over here 😛

my crt's all need servicing, my best one is a computer crt, it's pretty nice, but it ain't the same

carmine pine

what the heck...

weak zinc
#

ill post that back

carmine pine
#

one core, one crt, almost seems like a really edge case timing issue + this person's signal chain. they are doing vga --> bnc, it would be either 3 or 4 connectors.

#

thank you for checking it out

#

i was looking through the code to see if anything looked off, but of course it's solid

#

it's fixed!

#

sync on green

#

LOL

#

super weird

#

why do other cores look fine without the sync on green switch but this one doesn't though

#

gotta be something finnicky

weak zinc
#

LOL

carmine pine
#

i am super confused, usually if sog switch isn't on and it needs to be, prety much every core looks wrong

#

maybe it's just cuz it's a 2x clk, much faster video clock

#

lol

weak zinc
#

🙂

carmine pine
#

sorry for bugging you

I dont get it

this looked like a job for a scope for sure when i saw what looked like ringing

#

SOG was turned on only for the one core?

the physical switch was turned off for all other cores, everything's fine supposedly, then for this core it's not fine lol

Cycle accurate Master System emulator. The goal of this project is emulate Sega Master System chipset accurately as possible using decapped chips photos.

Master System chipset
US Sega Master System consist of 3 integrated cicuits + RAM, ROM chips:

Zilog Z80 (CPU)
Yamaha YM2602B (VDP)
Sega 315-5216 (IO)
Nuked SMS currently targets US SMS model 1, thus SMS2/GG VDP extensions are not supported.

Additionally YM2413 is emulated.```

Maybe there are plans for a separate GG core

livid spire
#

Yeah. I mean, very very early to have the thought, who knows what will happen. Always great to see new work being done.
Only to highlight my own interest in some of the seldom used SMS2 video modes after some tinkering myself. Not really sure how much is utilised outside of homebrew, but I believe some SMS2 exclusive functions are around

carmine pine
#

It's probably because the GG VDP hasn't been decapped

#

same with the SMS2

#

i would guess anyways, not sure if they have already

#

a new ym2413 core will be nice too

carmine pine
#

not for awhile anyways

vital idol
#

plus I don’t think the implementation philosophies are compatible? I believe they would need to decap an sh-2 and implement from traced silicon to be included.

It will be interesting to hear if the Nuked guys plan to do more chips and systems after they have finished MS1

@viral heath do you know if this ever booted before? I'd like to look into the graphics and see if there's anything I can spot. But every single old build of the core I have doesn't boot it.

OK, not my fix, but I think I know what's going on. If you load WWF Wrestlemania first, then load Raw (on old cores as well) it loads. So I'm checking to see if the eeprom state fixes for most of the T-81xx games will fix it and if so I'll add that PR.

# viral heath Thx ur the best aenar ever

I'm just a dingus doing dingus things in the shadows of giants. Srg/Sorg/Robert and all the other devs on this project are amazing. I'm just stubborn and hit my head against small problems until they change a little. Hehe.

west sable
#

Your efforts are appreciated

cloud otter
#

What I've found so far is that A15100, the register that handles adapter control, never gets handed off to SH. So it properly is set to 0x0083 on boot (vdp auth - SH2, no reset, 32x on) but the Super32x system reg (which maps over that and does a passthrough on the last 8 bits) never gets set to 80 (VDP access - SH2). Manually injecting that doesn't fix it (it's a read only reg from the Genesis side) so whatever process hands off isn't doing it in this game. Note, it's also broken in Gens (emu). I'll keep poking though.

cloud otter
#

When it gets in this state, it's recoverable by resetting (in this order) 68k, SH2, SH1. So that gets me closer to the chain of events.

viral heath
#

Sorry for it, that appears...bad...

cloud otter
#

Nah, it's a fun thing to try and figure out. I'm sure a veteran Sega dev would know exactly what to do... but I have to learn it as I go and that's part of the fun.

#

That being said, I'm potentially out of my element on this one. But I was out of it on the last one, too. So we'll see how it goes.

#

While I was looking up resources, I did stumble on this patch... which uses the more powerful 32X processor to handle Golden Axe, making it much smoother. I haven't done a side by side, but it runs on the core and seems smoother.... https://www.romhacking.net/hacks/7112/

A lot is an understatement.

Didn't realize Re-Revenge had a MD+ hack. It's already an excellent hack.

I'm sure MD+ being added to Mega Everdrive Pro officially didn't make some parties happy.

I have the Super SD System 3 and I like it, but I heard it still has issues with some CD games. It doesn't have the audio issues that Turbo Everdrive Pro has currently, though (though I like the EDPro too).

and the latter fits better in the TG-16, while I have the System 3 in the Core Grafx.

It's amazing what has been done with some of these SoR2 hacks.

It really is. If you build something on one of the greatest games of all time I guess you really have to show up, hehe.

carmine pine
#

but yeah msu-md has advantages

#

the special ssf2 mapper variant they made won't be integrated though i think

cloud otter
#

Ah, I shouldn't have used the term. I just know it gets heated for reasons beyond my understanding.

carmine pine
#

i'm kinda bummed that md+ is the de facto standard because msu-md was sufficient and could run on original hardware without special mods

#

but it is what it is

#

it's easier to loop in md+ which is why it's preferred, and editing the loop points is effortless practically by comparison

#

so there's a good reason why it's preferred

west sable
#

Yes, the loops are specified by the sample position in the cue file per "track" (wave file) and it is a good format. Be that as it may I am fully aware of why it will not be supported so I am not going to ask for it anymore either.

carmine pine
#

nothing is stopping it from being supported other than someone with the know how not having added it yet

cloud otter
#

I preferred Betamax and HDDVD (neither of these are jokes). But the market's gonna market sadly.
The HDDVD thing was not because of the tech though - I'm not insane, so far as I've been told. At the time they were the only discs with special features. Bluray was the movie and that's it for a long time.

carmine pine
#

there is no technical reason it isn't supported

#

i feel like when i criticized the existence of the format requiring more than just original hardware (in fact, originally requiring an expensive product made by the creator of the format) it was misinterpreted as me having some authority over whether or not it gets implemented

#

that is not the case

cloud otter
#

I know that I tried to look up MD+ once and the specs were completely walled up behind... I wanna say Terraonion's side actually. Sounds like it's at least a bit more open now.

#

That might be the same creator ...

Has anyone here worked on 32X in the past? Beyond pulling in the SH changes, like actually looked at the code? I'm stuck. I know the exact moment it locks up (ori.l on 68k side to A7, while incrementing the value in A7) but I have no idea what part of IF.v is actually commanding that moment. It feelss like ADCR.FM needs to also be updated (it's a register that needs simultaneous write per docs that I won't share here) and that's preventing the remainder of the megadrive code from running. But I'm under more water than a dolphin trying to find his pod.

#

If anyone wants to pop over to dev-talk or DM, I'd appreciate it.

Anyone know if there are any known composite sync issues with the current core(s)?

the megadrive core?

how do I stop Genesis_20230224 from downloading every time I run update_all? (I assume this is the old outdated core)

but, to each their own 🙂

blurays kept using pretty bad mpeg2 encodes for a fairly long time

#

hd-dvds were usually quite a lot better despite the lower bitrate because they were using h264 or vc1

#

only for like the first 18 months or so though, bluray caught up then got pretty obviously better

astral merlin
#

depending on the HMV publisher, yes. Sony and a few others figured out early on that if you wanted people to upgrade, it had to be a WOW. Many people reasonably "couldn't tell the difference"

#

between HD and SD, that is

fickle hemlock
#

planet earth on hd-dvd was mind blowing at the time

astral merlin
#

striking new transfers, compressionist workflows, etc and even TVs all took a while to converge before the "a ha" moment

fickle hemlock
#

my favorite thing about hd-dvd is it was part f the actual spec that when you put the disc in the movie had to play

#

no trailers or anything allowed

#

And "lossy" is meaningless to consumers. TVs back then were washed out LCDs or DLP at best. I was literally working in film and we all preferred HDDVDs (again at the time) simply because they had to hit a higher standard to pass cert with Toshiba and Microsoft.
I can master you a 4K UHD right now that looks like garbage. And most people were just rushing to market. I think a lot of it had to do with the fact the PS3 was the only consumer Bluray player for a long time. The crap companies threw on a disc back then was nuts, quality wise.

#

But we all know MegaCD is the only way to watch a movie, honestly.

astral merlin
#

we had a Pioneer plasma, the black levels (and color depth) were immediately noticeable on VC1/AVC discs — more so than the resolution bump (to me and my husband)

#

even later, there was embarrassing Blu-rays: Poltergeist and Pirates of the Caribbean were both bad transfers, bad compression, and low-density

#

but I agree, give me Sewer Shark or give me death 😉

# carmine pine the megadrive core?

Yeah. I've discovered that the analog output does "weird shit" if composite_sync=1 is set for the MD and 32X cores, no other core has the problem, the 2 Sega cores seem to be outputting a really weird sync signal with that enabled, but outputs correct RGBHV with it set to 0.

how do I stop Genesis_20230224 from downloading every time I run update_all? (I assume this is the old outdated core) and the Genesis folder from being made in my games folder?

#

or is that not possible?

# modern stream Yeah. I've discovered that the analog output does "weird shit" if composite_sync...

that's correct. you don't want to use composite_sync if your output is rgbhv. the composite_sync option is for rgbs, yc (s-video or composite via external adapter)

Hello people, I have been testing the new naked core of Mega Drive and in the absence of adaptive composite blend I have been using it completely and I am thinking about whether the adaptive or the complete one do you prefer?🫠

manic ridge
#

Adaptive didn't always work so really it's almost better to just have it on. It works even better with scanlines etc.

#

IMO

The composite blend is such an interesting effect.
I use the YC INI settings without using the core specific setting anymore. Amazing you somehow get the best of both worlds, really clean nice video (relatively composite speaking I suppose), but also the blend effects where they should be.

manic ridge
#

I don't like composite blend by itself without scanlines it looks weirdly blurry

pine crystal
#

If you're going for 'authentic', real CRTs blurred the whole screen... so it's either all or nothing for me.

#

I never liked Adaptive. The results were too inconsistent with regards to where it decided to apply the blending... or not.

carmine pine
#

i got used to just blending turned off and just the regular interpolation video preset

#

show me all the dither dots

pine crystal
#

I mean, if I'm serious enough about 'getting rid of' the dithering, I'll hook it up to a CRT and do it properly... The Way It's Meant To Be Played™️ 😏

I saw the same thing as you with an extron (203 rxi in my case) where using rgbhv in helped with sync issues, but using rgbs caused it to roll (same with nuked MegaDrive core)

Hey, got an odd question for you all. I've never been able to figure out how to get my Rock Paintings CD+G disc that came with the Sega CD in 1992 to dump to a .bin/.cue format properly and am not versed on how to get it into a CHD format, so i went and scoured for an existing image. I found one in ccd/img/sub format, but the MiSTer Sega CD core does not seem to be able to play it. Suggestions on a) if it can be done, and b) how I'd accomplish such a thing?

simple apex
#

hmm, one of the oddities with CD+G is the +G is in the subchannel data on the CD, which famously bin/cue doesn't [really] capture

long cairn
#

appreciate it! will give that a try

lavish sonnet
#

that thread is wild

long cairn
#

yeah. saw there was a link to it too already in chd, but broken of course

lavish sonnet
#

i also got excited when i saw that, and lou reed

#

i don't think the glitches are 100% ironed out on Sega CD, and I think zakk was the only one brave enough to try with that core

#

like pce, psx, saturn should all work too, but i don't think support is there

#

having said that i didn't have any issues with the one CD+G i tried on Sega CD a couple years back so

#

it shows up on wayback but says it isn't archived...that hurts

The core, I'm finding, is more simliar to Gens than to anything.

Regarding composite blend, just a reminder I find kinda funny. Basically all these old game consoles did it, 8 bit, 16. The Sonic waterfall is such a go too example it always makes it seem like a Megadrive only problem.
So many great MiSTer solutions to work around, but I always find it odd it only seems to be considered on this core

stuck gull
#

It’d be appropriate to have it in the sms core yea

#

It’s in the Saturn one but doesn’t seem to be functioning

drowsy halo
#

And it's very easy to see with the waterfalls, That it's a good go to example.

livid spire
#

Thanks, that probably is part of why it is a considered on Megadrive/Genesis often alright.
It wasn't really something I thought much of until I got MiSTer and RBG cables.
SMS is certainly riddled with dither blending type effects everywhere!
Ninja Gaiden (or one of those) has a really bizzare effect too that requires composite to work

drowsy halo
#

Haha yeah you're right, it's everywhere

#

TBF I fired up Sonic 2 on my Genesis over composite earlier into my PVM, and that waterfall effect really does work amazingly well.

#

Almost makes it a shame to run it over RGB instead.

#

Another alternative of course is to use one of those VGA to conposite/YC adapters which do a great job, although I wanted to run one off the monitor output on my Extron but it doesn't provide the 5V on pin 9 😦

well i can't get CD+G to work, that is a bummer
