I did it but it didn’t worked for me😔 I will try again when I get home. Thank for the help

tulip surge
#

not too sure why it wouldnt be visible
If you copy roms directly to '/media/usb0/games/MegaDrive' do they show up OK?

#

When you load a game in the core, it'll default to whichever directory it finds first
/media/fat/MegaDrive
/media/usb0/MegaDrive
/media/usb0/games/MegaDrive
/media/fat/cifs/MegaDrive
/media/fat/cifs/games/MegaDrive
/media/fat/games/MegaDrive
So you dont want the first 2 to exist if your games or symlink are in the 3rd

woeful goblet

#

I guess delete the symlink and create it again, see how it goes

Sounds good, and just be be sure, you created the links in /media/usb0/games/MegaDrive ?

What are the benefits of that hack vs the PSX Mk Trilogy, besides no load times for Shang Tsung morphs?

hard silo
#

Don’t know

#

Here is the hack

#

You can also find pre patched in a…. romantic website

west sable
#

No. Just curious what the fuss was about

compact plover
#

It’s just a glitchy UMK3 hack. It’s a very broken game so it’s like playing a MUGEN version of UMK3 on Genesis

#

I think the selling point is that every variation of every MK character from MK 1-3 is playable

have not tried on MiSTer yet but this is super exciting. what an awesome project

fallow dome
#

It’s awesome on MiSTer. Probably the best way to play DOOM on a MiSTer now?

west sable
#

Better than PSX version?

#

Seems like Doom is best played modernly on a PC. Neat project tho

still a great way to play though, and you can use mouse/keyboard in the 32x core with that version

I just got my mt32-pi in the mail and assembled, and figured it would be a good time for a Doom video. This is Episode 1 in its entirety, on the Ultra-Violence difficulty level with no deaths. It's also my first time clearing any Doom episode without dying, and I'm glad I was able to experience it in its original DOS form for that.

I played through on my PIII box a little while ago using the SC-55 soundfont on the X2GS waveblaster, sounded really cool

west sable
#

During development was there any intended device for Doom, or is it just GM intended in its compositions?

shell compass
#

sc-55 was what it was composed on

west sable
#

That would be a good benefit then

#

Never had an external midi device in the 90s. This is all quite fun

oak jungle
#

I still really like the sound of the game with FM synth, just because it's very nostalgic

#

that's how my first PC sounded with some kind of onbaord Crystal FM thing I suspect

#

half the fun for me at least is trying the same game with different audio devices, soudfonts, etc and listening to how it differs

west sable
#

Just fired it up with Doom II which I think is also compatible (Sound Canvas in setup Id guess) and it seems to sound pretty good. Certainly a lot better than my sound blaster's renditions back in the day

fallow dome
#

I stand corrected, glorious mt32! elmorise

west sable
#

Doesnt seem like any midi device can make "guitar" sound better

fickle hemlock
#

yeah ao486 + fastdoom still the way to go imo

#

near solid 35fps , mt32pi, good mouselook

Has anyone made a full high quality set of arrangements for the original Doom and Doom 2 OSTs? I dont mean playing them on a Roland SC-55, but like something much higher quality.

or is that 3do

@fickle hemlock yeah but then I’d have to use a PC core and that’s for turbo nerds cringe

Anyone have found any major issues with the new Mega Drive core? From a quick test it looks and sounds great! 😱

manic ridge
#

Haven't tried it yet, I'm curious if it can/will be inserted into the Sega CD and 32X cores

hard silo
#

But some qol features are missing.

manic ridge
#

oh?

pale plover
#

I hope that features like the turbo and sprite limit get included. I liked that for games like Road Rash II

hard silo
#

I wonder if sorg able to add cram dots toggle

#

It’s a huge netlist he needs to navigate through

carmine pine
#

adding turbo and sprite limit won't be simple with this

#

the core uses a ton of logic space according to him

#

cores as a netlist will be extremely accurate if the compiler can make it all fit and meet timing requirements, he had to get some stuff adjusted in order to make it work, nukeykt was very gracious with the advice from sorg and willing to work with him, so that was great to see.

#

the future is bright for this core for sure

glass shale
#

New MD core even plays Pier Solar! Sorg did a great job merging features/mappers from old core on this one! chefkiss

#

Save states possible with this new core?

manic ridge
#

I'd have to think not?

fallow dome
#

aw, that means I’ll have to continue to git gud

manic ridge
#

Obviously I have no clue I just didn't get the impression that Nuke built it with them in mind

I'd like to see a few QOL added most importantly, someone mentioned a more advanced composite blur algorithm?

fallow dome

the SMS sound is personally very good

the visual effects don't work still, which is because maxim is abusing kind of an undocumented aspect of the sms vdp

Sorg mentions that something is wrong with TMSS

#

He asks us to disable it for now

Is it activated automatically if the boot.rom is set on MegaDrive directory ?

hard silo

No

manic ridge

What's TMSS

hard silo

Security system in later mega drive systems

barren plank

thanks for taking the time to give the core a spin an let us watch/listen in

versed rapids
#

I checked the OSD there is no TMSS option so how it could be desactivated if not the boot.rom ?

#

Oh speaking of TMSS, how do the early games that are incompatible with it react in the new core?

It’s set to No default

I see it is gray disabled on my side I didn't pay attention

Great!

carmine pine
#

cram dots sonic 3 bug is resolved, so that is likely a bus arbiter timing issue as well with the current core

#

those little bugs with pixels and stuff are likely because the core is not yet meeting timing without a few adjustments to make it work better with FPGA

pls check these on real hardware, sorg repoted garbage pixels in sonic 2 but turned out they're on real hardware as well

#

Yeah my pleasure! I’m sure it’ll be released to the public soon-ish as those two core geniuses work out the kinks for the MiSTer port.

#

All Genesis games are supported. Unless they use a funky mapper, I guess?

oak jungle
#

I think one major mapper missing is eeprom save support, which affects Wonder Boy V - you can run the game but you can't save

fickle hemlock
#

people keep mentioning asteborgs so thats working

west sable
#

ZX Spectrum port of Xenocrisis forthcoming

fickle hemlock
#

i wonder if they'll ever make like, xenocrisis2 or something

#

not that i don't appreciate all the ports

west sable
#

NES MMC5 port should be attempted just for shiggles

#

The SNES version of Xenocrisis really shows how weak the cpu is in the SNES

fickle hemlock
#

i think the last one i bought was ... n64?

#

i think i have enough copies now

shell compass
glass shale
#

These are all supported in the new core

carmine pine
#

There are some indie game companies that go out of their way for ideological reasons to make it so emulators won't be able to run their games at launch. They are companies that sometimes rhyme with solder-felon.

#

Pier Solar was only able to be supported because a mapper was added for the special chips on its cartridge.

#

Kitrinx made the reimplementation of that chip.

This is an excellent cover album of Mega Man 1 by Woodfrog that can play on a real Genesis, or the Genesis core on MiSTer. I built the VGM files into a bootable rom for the core, I cant link to it here but if anyone wants it shoot me a DM.

Adding savestate to nuked md is probably even harder than to existing genesis core tbh

Found a bug with pause on OSD: at the end of the bonus stages in Sonic 1, if you keep opening and closing OSD you’ll hear the “SEGAAA” voice over a couple of times! 🤣

#

It actually happens anywhere in the game haha

pale plover

Cool a dedicated SEGA™️ button!

proper agate
#

Is the nuked core bigger or smaller than the existing core (without 32x/scd)?

carmine pine
#

last i heard

#

but it's based on decapping and traces so it's more accurate

#

s32x has a rewritten bus arbiter so one of the main sources of problems in the genesis core shouldn't be an issue in the s32x core

jagged sage
jagged sage
#

One thing I notice is with the same filter and settings, the color volume is higher with this core

jagged sage
#

Tested a few more.. I am really impressed with the color saturation. Truly impressive.

carmine pine
#

It looks kind of the same to me. The background is just different and brighter there. I'll compare with 240p test suite maybe...

#

The real megadrive has a pretty big handful of variations for this color representation in the real world, but the rgb values are all you gotta worry about for it pretty much.

edgy ruin
#

@warm falcon could probably confirm it but I don't think rgb values are going to be magically more accurate from the decapping only, as this is analog stuff mostly.

compact plover
#

Does this new core offer eeprom saving for those games that are missing saving on the current core, e.g. NBA Jam and Micro Machines?

Anyone know how Sorg is getting on porting nukeykt's core?

@nukeyt: since you are on it, apparently, there is also a dissimilarity between the Blue channel and Red/Green channels for one of the specific level used in SMS compatibility mode. This was first discovered on SMS VDP (see https://www.retrorgb.com/sega-master-system-non-linear-blue-channel-findings.html) then confirmed by looking at the die shots of both SMS and MD VDPs (see https://www.smspower.org/forums/18235-NotesMeasuresNonlinearBlueOnSegaMasterSystem1OtherFindingsByBfbiii)

I recommend everyone interested to throw a Patreon sub towards checking it out. The minimum is $2 if you just want to test the differences for yourselves. What a steal!

Sorg deserves that! He's doing God's work with the MiSTer platform!

calculated them

# 
    int rgb_val_m5[18] = {
        0, 18, 36, 54, 72, 91, 109, 127, 145, 163, 182, 200, 218, 236, 255,
        85, 102, 170
    };

    for (int i = 0; i < 18; i++)
    {
        double x = rgb_val_m5[i] / 255.0;
        double r = 1.2 * 3;
        double rup = 5.6;
        double rdown = 5.9;

        double up = ((1 - x) * r * rup) / ((1 - x) * r + rup);
        double down = (x * r * rdown) / (x * r + rdown);

        double val = down / (down + up);

        int vl = int(val * 255.0 + 0.5);

        printf("%i %i\n", rgb_val_m5[i], vl);
    }
#

r is resistance of DAC between gnd and 5v. rup and rdown are from schematics

edgy ruin
#

I see, so the non-linearity measured at the output is actually caused by outside resistors but the dac levels are linear internally ?

warm falcon
#

yup

edgy ruin
#

So that means RGB mods that bypass analog video circuitry and connect directly to VDP R,G,B pins could in theory restore the linearity (or produce slightly different non-linear levels) ?

warm falcon
#

yea, if they properly buffer them

edgy ruin
#

interesting, thank you

carmine pine
#

what is noted as "correct" is going to depend on what you are using as a reference machine in this case

#

there are a lot of subtle differences for the most part

#

japanese md1 vs md2 for instance from an article online. striking difference in the output

edgy ruin
#

yes, the french MD (RGB model) uses a scart adapter with some circuitry that might also modify the voltage levels, who knows

carmine pine
#

in then end, i think the core should output RGB and then people can modify with filters themselves how they see fit, imo

#

this isn't a situation like the NES with color palettes and there is no 1 standard. there are also not a lot of games that look garish or ugly with pure rgb (like the pc engine had)

#

just my personal take at least

#

adding a switch like the pc engine core might be nice though to retain the previous genesis core look as an option

#

(i know it's probably going to vary based on system though)

warm falcon
#

no, I calculated my own values

carmine pine
#

nice, thanks for the response

warm falcon
carmine pine
#

ah, i should have scrolled up more lol

#

nice thing with that is if anyone wanted to another LUT like that could be added and a switch could be made to cycle between the two

#

there are a lot of different variations but there's nothing as dramatic a difference like seen on the NES though for instance

Like that stuff would’ve been pulled over from the old core verbatim I assume

One to check to see if things have been ported over would be Virtual Racing which had the special chip added to the Genesis core

Do roms go in a different folder for the new core?

Yep, MegaDrive directory now

Although obviously you can still just browse to your old Genesis folder 😄

Sonic 2 TAS rom hack desyncs on Chemical plant, most hardware do this though.
Tecmo World Cup loses percussion too, like a Genesis 2.

I don't have any controller (M30 2.4G) working on Micro Machines 2 - Turbo Tournament.
Do I need to activate something else, like the J-Cart option ?

Loaded up the new core and having a strange issue…loaded up TMNT The Hyperstone Heist and noticed that after pressing the C button a couple of times in-game that suddenly player 2 joins the game and C button suddenly starts acting as Start?

So far on my quick tests.

  • Darius works as intended on the pause mode,
  • Demons of Asteborg is correct on the intro (PSG channel);
  • The Micro Machines games work as intended with the music (just activate the J-Cart option on the core options).
    Impressive, most impressive.

I don't know if one day it will be possible to have an 'Adaptative Composite' option like on the Genesis core.
And something stupid, have the possibility to use a "boot.rom" detection, for example for custom boot ROMs.

compact plover
#

One missing feature I noticed too is that the Miracle Piano controller isn’t supported on the new core but it is on the old core

hard silo
#

Adaptive composite will be difficult to implement

#

@earnest coyote

#

Any opinions

plain quiver
#

I'm just asking like that, but I understand quite well that some ideas could be difficult or even not in the scope of the new core following the next eventual replies.

Didn't realise that both the MD/Gen cores were somewhat interlinked. Thought I'd be clever and just filter out the Genesis core in my downloader.ini and it'd leave me with this MD core but alas, it's all or nothing currently. Spose it's a good thing for the time being given the different features.

Does mouse input work with e.g. Cannon Fodder? (Mouse should be P2 port.)

I haven't looked at the MD core yet though as all my MiSTer stuff is on a moving truck somewhere.

#

Adaptive is missing

There used to be a guy who worked on an "FM Genesis"-build of Genesis-core that had more advanced blending but currently they've just disappeared from the internet it seems - no sharing of the core's development files either

knotty walrus
#

I just looked at the clocks and holy

limber pine
#

Anyway, just discovered that interestingly enough this core seems to somehow work with MikeSimone's S-Video/Composite Adapter on NTSC-mode

Has a some wiggling dot crawl which IDK if it's due being on wrock clock speeds or parameters - but rn the composite output's much cleaner and less prone to creating artifacts around most of the sprites incase I ever had the sharpness settings on my TV go even slightly higher than 25%

#

The native composite blend works perfectly too btw

#

@weak zinc

Does this core need it's own parameters implemented or can they be added from Genesis-ones via yc.txt?

weak zinc
#

Yeah it's a copy and paste of the values just replace genesis with megadrive

plain quiver

#

Prolly should take pictures for comparison as this was hard to ignore when I played the main Genesis-core via Compoosite through my 21" Sony Trinitron

heady obsidian
#

Is the sprite limit option/turbo in the Genesis core that usefull? It is, i think, missing in the new core.

Furthermore, can the 32x core could be based on this new core ? Is there enough space? (with cd support elmorise )

limber pine

Is the Nuked-MD basically outputting RGB-colors over what the native console's intended colors?

Genesis was native RGB

through a Sony CXA encoder that converted it to Y/C and Composite

the old adaptive composite blend option had many issues. hopefully someone will work on an updated method that does not negatively impact the visuals as much in other areas

How do you enable TMSS 🙂 Is there some kind of BIOS ROM?

#

Also any plans for a Controller Type setting? Especially for SMS games this is needed. Or Great Ice Hockey's menu has a mind of its own unless you use a SEGA Sports Pad.

glass shale
#

@frigid tapir just put the TMSS bios/rom as /media/fat/games/MegaDrive/boot.rom and enable the feature in the OSD menu

manic fractal
#

any chance XBAND could be implemented in this core? could be interesting now that the revival has taken off

frigid tapir
#

How would XBAND work?

#

I am guessing RETRONAS would need to be updated for this core to automatically point to my GENESIS folder?

shell compass
#

this new core takes up a far greater amount of resources than the old one and will probably need to be optimized quite a bit to get all the extra features in. would love to see xe-1ap input support as well eventually

frigid tapir
#

Well that is all the issues I raised with the previous Core tested... this Core is behaving exactly the same way as my Early Japanese Model 1 Console 🙂 wow!

Even the CRAM Dots behave as they should do!

glass shale
frigid tapir
#

I was super sceptical previously (to be totally transparent) but this thing so far is spot on. I can't find a single difference / issue with any of the problematic games.

glass shale
#

I was also impressed with it since first test version release by sorg couple days ago!

frigid tapir
#

You can tell this has been done by analysing the chips 🙂

compact plover
#

Is it safe to say this is technically the most accurate console core now?

frigid tapir
#

It sure looks, feels and sounds like it from where I am coming from! 🙂

#

And it makes sense that its as good as it is. Especially with what we saw of the photos of the chips 🙂

glass shale
#

It's probably the most accurate Sega Genesis/MegaDrive FPGA core yeah

frigid tapir

#PreservationRules

glass shale
#

This is how sorg defines this core (from his Patreon announcement today): "This is a replica of real hardware (unlike functionally similar Genesis core)." misterkun

frigid tapir
limber pine
#

Is this also the only core to be a pure replica of a real hardware?

tidal python
#

No, but it was made entirely using decapped chips.

narrow jasper
#

any plan on replacing parts from the genesis cores to the ones from the Megadrive ones in the MegaCD and 32X cores?

compact plover
#

Just curious, why don't other core devs do the same decapping process? Is it because it takes up a lot more logic and is a much more difficult and longer process?

frigid tapir
#

I would imagine its incredibly delicate to do the more complex a chip is. You risk damaging it as you decap it?

frigid tapir
fickle hemlock
#

decapping needs expensive hardware and also skill to do

#

and even then the end result is basically a gigantic jpeg that you still need to convert into actual code

I thought the new Megadrive core is becoming an umbrella for all 3rd/4th gen SEGA consoles

Once it has feature parity with the original Genesis core, I’m sure that one will be sunsetted and the new MegaDrive core will be the main one

I mean, it’s supposed to be much more accurate, so I suppose it could eventually get incorporated into an eventual “improved” 32X core maybe

#

Well, I didn't even get to MDFourier testing and there's already a sound problem: After Burner II emits an annoying high-pitched whine.

#

Doesn't matter whether MiSTer is set to 48KHz or 96KHz, the new MegaDrive core squeals non-stop with this game.

#

I will say, by ear in games, PSG sounds like it might be mixed too loud.

#

Now to run MDFourier.

manic ridge
hard silo
tidal python
#

I had some trouble getting a good capture as the optical input on my sound card is being a pain in the ass, but I was right: PSG is too loud.

DA__ALL_AVG_A-MD1UTVA3-M192_vs_NukedMD_96KHz_0000.png
#

Model 1 filter, YM2612.

#

Oh, one more thing: Thunder Force II's timings during transition screens is now a match to the hardware. On the previous core, the final note on the GOOD LUCK screen would get cut short. Not anymore.

glass shale
#

Who can open an Github issue for that?

tidal python
#

Yeah, PSG needs to have its volume reduced.

glass shale
#

Question is: why did sorg increased that volume?

tidal python
#

But that squealing noise in After Burner II was never present in the old core, so I don't know where that came from.

glass shale
#

Oh, two issues then!

#

Gotcha

tidal python
#

As for the volume increase, I can't say. Maybe it's based on how numerous MegaDrive clones mix their PSG louder than they should?

warm falcon
#

after burner issues seems is caused by PSG resampling

#

game just sets PSG frequency to highest possible

tidal python
#

I had a feeling it had something to do with PSG due to how it's being used to play back samples.

warm falcon
#

ab2 sounds fine in my test code

tidal python
#

Aliasing that is getting through.

#

That will need to be filtered out in some way.

glass shale
#

I think we need to get a Github issue opened. At least to get discussions initiated with sorg.

hard silo
#

I think what is best here is also include mdfourier evidence

glass shale
#

Agreed

limber pine

#

The old one does

limber pine

I tried it on the old core (hence why I said "current") with the boot.rom-method but it doesn't work there (the regular TMSS-rom does tho)

thorny verge
#

commit seems before public so I can't revert it myself

hasty shadow
#

what's the point of enabling TMSS? Is it just to show the licensing text before the game and make it so that some games don't work?

#

for nostalgic reasons?

#

and authenticity

#

seeing that black screen when loading an unlicensed rom is awesome 😄

pale plover
#

It's so you have an excuse to not play the Osomatsu-kun game.

hasty shadow
#

ah nice, I was looking for an official game that didn't work with TMSS

#

that one didn't work perfectly

warm falcon
#

does it work if you force japanese region? TMSS in japanese consoles omits some checks

hasty shadow
#

yep

#

same with Alex Kid Japanese version

limber pine
#

I'm mainly looking to have authentic (or close to that) boot screens upon booting a core, hence me exploring to see if TeraDrive's TMSS-rom would work as boot.rom on the Genesis-core

(Also not really into Mister FPGA Custom Bios Roms myself)

frigid tapir
#

Maybe its my ears, I am not hearing this audio issue with After Burner II ?

#

I am now running it on my Japanese Mega Drive Model 1 and it sounds the same to me.

carmine pine
#

Yeah sorg said to disable the tmss rom option in his last Patreon early build. This release must have it sorta not functioning for now still.

manic ridge
#

And to be clear, enabling it doesn't gain anything other than that text, but you may also lose functionality for some mostly unlicensed games?

carmine pine
#

I don't remember on that part. The Genesis core had a workaround to get around that, I don't know if there is a workaround in the MD core as well put in by sorg. His cartridge module might show that

knotty walrus
#

And Osomatsu-kun

#

Anyone notice that the new core is much more shimmery over YC than the previous core?

rapid elbow

I'm setting up the new mega drive core. What's your opinion about the best audio filter and fm chip selections?

#

Additionally I'm having trouble understanding 320x224 aspect correction. Is there a time when it's accurate and not?

limber pine
glass shale
#

2612 with model 1 filtering seems to please most of people

shell compass
#

for me it really depends on the game. for authentic sound and to tone down some harshness I prefer model 1 filtering

for some games minimal filter sounds great though, but can expose harsh twangy sounds at times depending on how the music/sfx is made

glass shale
#

No filter, right?

tidal python
#

No filter for both of these. In fact, filter on or off, at least with the model 1 filter, doesn't change the volume balance at all.

glass shale
#

Ok. Do you have access to github? I think you have been tagged there @tidal python

tidal python
#

I do, yes.

glass shale
pale plover

Worth noting some games also swap between resolutions, like between 320×224 and 256×224. Battle Mania Daidoujou and Monster World IV both do that as an example.

glass shale

#

If you want original aspect ratio and your wondering about the aspect correction, one interesting aside is PAL games. There, leave that option off, but if you add borders you get the original aspect, closer to wide-screen. Can trim from there if you want a larger screen over HDMI

#

Seems most people just go 4:3 (if they'd even touch PAL). I always find it odd the aspect ratio is completely incorrect though

manic ridge
#

I just go 4:3 I'd rather play games then try and pick different aspects for each game

#

If it would save the per game setting, that might be different

tidal python
#

Honestly speaking, the Model 1 and Model 2 filters should also change the PSG balance, but the latter should be compared against either the VA3 or VA4 model 2 (though the VA4 has FM mixed in a bit louder).

warm falcon
#

sounds pretty close, maybe a tiny bit louder in mister

glass shale
#

So the core is a VA0 then!

#

@warm falcon which chip and filter on MiSTer?

warm falcon
#

ym2612, model 1 filter

tidal python
#

MDFourier shows the volume levels are off by about maybe 1.5dB.

#

Again, comparing against a VA3 model 1.

is CD+32X going to be a thing? I'm quite late to the party here 😅

rapid elbow

I'm toying with the game Astebros and the map has a perfect square for rooms with aspect ratio correction.

I guess 32X is srg320's thing

knotty walrus
#

Probably not

hollow nimbus
#

I have @native rain 's boot roms installed and the new MD core doesn't seem to pick it up. Is it because of the TMSS feature that is also looking for a boot.rom file?

limber pine
#

Tried Ecco The Dolphin today, did notice the title screen/opening level track's lower in volume than on the Genesis-core

carmine pine
#

Cores that do have a bios will usually have different names for the boot#.rom to be the auto start rom

Remove the /media/fat/games/MegaDrive directory in the SD then run: ln -s /media/fat/games/Genesis /media/fat/games/MegaDrive

Oh scratch that, that’s for SD

#

Sorry

#

If you have ssh access to the Retronas shell you could run the same command and adjust the paths

frigid tapir
#

right ok I have terminal access to Retronas

#

So what would I need to change in terms of paths?

glass shale
#

The absolute paths for your Genesis and MegaDrive game folders

#

Inside the Retronas

frigid tapir
#

\retrosmb\retronas\roms\sega\MegaDrive ?

glass shale
#

Bam!

#

Oh wait

#

That’s the SMB path

#

That’s external to it

frigid tapir
#

Yep. I am not the greatest when it comes to Linux commands.

glass shale
#

You need to figure the internal path on disk

frigid tapir
#

So I understand the concept of what I am trying to achieve but not the actual command to do it 🙂

#

Basically I want to link the MegaDrive folder to Genesis as they are one of the same for me.

glass shale
#

ssh it then run df -h

#

That will give us the mount point for your roms disk

frigid tapir
#

/dev/sda1

glass shale
#

What’s the mount dir it shows?

frigid tapir
#

ah mount point is /storage

glass shale
#

#

cd /storage

#

Then ls

frigid tapir
#

yep when I ls I see lots of things including mister as a directory

glass shale
#

cd mister

#

Then ls

frigid tapir
#

then games?

glass shale
#

Yep

#

MegaDrive and Genesis are dirs inside games?

frigid tapir
#

then cd Genesis where all my games are

glass shale
#

Not yet haha

#

Are you inside games?

frigid tapir
#

yes

manic ridge
#

At this point why do Genesis and Megadrive cores need separate directories lol

glass shale
#

Does your MegaDrive dir contain important stuff?

frigid tapir
#

root@retronas:/storage/mister/games

#

Weirdly I can't see a MegaDrive folder.

glass shale
#

Easier then

#

Inside the games dir run:

#

ln -s Genesis MegaDrive

frigid tapir
#

Ok that command seemed to go through

glass shale
#

ls and check for MegaDrive folder

frigid tapir
#

Yup MegaDrive folder now exists

glass shale
#

cd into it and ls

#

It should contain same stuff from Genesis folder

frigid tapir
#

all games show in that folder 🙂

glass shale
#

Yay

frigid tapir

So when I next launch Nukey's Core it will see that and default to it?

queen hazel
#

Please type the full thing in one message

frigid tapir
#

This is on the proviso that you don't already have a MegaDrive folder though under mister\games

#

Plus depending on the retronas setup, your mount point might be called something different to mine.

#

I stuck with Bob from RetroRGB's video on this so called it storage.

manic ridge
#

Hmm doesn't the new core create a directory?

frigid tapir
#

It didn't for me (unless I somehow did something wrong).

#

Unless Retronas also needs its MiSTer script run again to update it? (I had to do this for NeoGeo-CD to work).

glass shale
#

Yep it all depends on where is the MiSTer directory in the RetroNAS

frigid tapir
#

Copying what I did (under your awesome instructions) might confuse some.

glass shale
#

Not sure if downloader is compatible with CIFS though

manic ridge
#

so if you already have Genesis and Megadrive how do you symlink them

glass shale
#

rm -rf MegaDrive then ln them

manic ridge

So run rm -rf MegaDrive then go ahead and run the command from before?

glass shale

Yep! ln -s Genesis MegaDrive

alright let me see if I can write this up

manic ridge
#

To symlink the Genesis folder into the Megadrive folder

From the terminal, navigate to /storage/mister/games, then:

  1. (If you don't already have a MegaDrive folder, you can skip to step 2)

Type the following command

rm -rf MegaDrive

  1. Type the following command

ln -s Genesis MegaDrive

shell compass
manic ridge
#

@glass shale how's that

#

let me know if there needs to be any corrections

frigid tapir
#

From the terminal, navigate to /storage/mister/games, then:

this is where confusion could set in. My mount point is setup as storage but others may have called it something else during the Retronas installation and config.

manic ridge
#

well I mean we don't want to type a tutorial about storage, so what's a simple way to explain it that's agnostic lol

frigid tapir
#

I would start with df -h

manic ridge
#

someone could then link to the pinned comment and fill in the blanks

frigid tapir
#

df -h will then show the drives and mount points which will help I think 🙂

manic ridge
#

alright let me do a simulated run from WinSCP lol

glass shale
#

If /storage is not standard for all RetroNAS setups then it would require df -h to see where is the mount point

manic ridge
#

I mean you'd still need to be able to identify your storage right? Like right now I don't even know what I'm looking at when I type df -h it's all greek to me

Point being at some point this is going to turn into a Linux tutorial

#

I guess I can see the "mounted on" part

frigid tapir
#

usually its an entry next to /dev/sda that you are looking for.

#

see this is getting complicated 🙂

Well would it be possible for you to write that part

then we can append it to the beginning

frigid tapir
#

can you see mine is /dev/sda1 Mounted on /storage ?

manic ridge
#

yep

#

question, if you have the folder on an external drive would it be a similar procedure to find the directory?

frigid tapir
#

Yes I would imagine so

manic ridge
#

so like the first part of the instructions should say "If you have external or network mounted storage"

#

I need assistance from someone versed in Linux and file systems

frigid tapir
manic ridge
#

alright perhaps they can assist when they have time 🙂

Wait how long has JT been here lol

In this server? Since forever I believe? 🤣

yeah I kind of remember seeing him on occasion it's just a shock when it happens

pale plover
#

So any word on adding EEPROM saving? Because several games kind of need that.

glass shale
manic ridge
#

oh yeah I thought someone did

#

but I just was looking at the github and nope

glass shale
#

Sorg said he’s adding some more mappers to the new MD core

#

Maybe he’s on a roll and it should be the best time to request EEPROM support 🙃

manic ridge
#

I mean that was my exact thought process

#

seems like he's making it his new baby

pale plover
#

Speaking of mappers, how does the core react to bootlegs?

manic ridge
#

I can make the EEPROM github issue if nobody else is

glass shale
manic ridge
#

k lol

let me know if I should change wording

#

I think I will replay Pier Solar on the new core. Now with the pt_BR language haha

#

I’ve finished it 10 years ago on GenPlusGX

#

Awesome RPG!

#

I have mixed feelings about being the creator of the device used to dump the game 😅

Support Fonzie cringe

vital idol
#

What about the people who paid for their games and never got them?

#

Would love to see paprium supported eventually so I can enjoy the money spent 😆

glass shale
#

Didn't Fonzie honor all the Paprium backers by now?

#

Luckily I got mine. Including the leather thong! 😏

vital idol
#

Looks like the sega 16 forums are dead, but there were several posts going back quite a few years of people who still haven’t gotten their copy.

#

I was stupid, I knew the history and decided to try with the more recent edition 😉

glass shale
#

Fonzie will never see my money anymore 😌

vital idol
#

Well, it was a gamble. May never see my copy, but I knew that going in. Still wouldn’t mind a version I could play on the mister, and I will not feel one bit of regret playing it that way.

glass shale
#

I have two Pier Solar carts

#

Yep. My Paprium has been shipped to Brazil just fine

#

Is there a full dump out there?

#

I thought project littleman was vaporware

#

Hopefully they will release a full EEPROM dump soon

#

DatenMeister is a STM32F4 lol

#

Fuckers

#

I'm fine by playing the game without STM32F4 generated audio haha

#

Let's make them public! 😄

#

Well, probably we shouldn't have this kind of convo in here 👀

#

Fonzie is a clown that doesn't deserve any kind of respect

#

But that's my opinion only

vital idol
#

Respect is a two way street.

I updated the custom db to rename it to boot1.rom auto so not to interfere with the new core (especially if people symlink the Genesis folder it will screw up TMSS). Also, it looks like the new MegaDrive core doesn't daisy chain boot1.rom yet so I can't do much. We'll have to wait and see.

oak jungle
narrow jasper
#

yeah, it's still here. my Megadrive died for unrelated reasons though

#

the main issue is that dumping it requires glitching security bits

#

if you get it wrong the data is cleared

#

so I need to secure a bunch of STM32

#

and that's been an issue

#

you need to have the glitching right first try so ...

#

and then I had other projects going on so that one went on hiatus for now

#

I might ship the cart to someone more experienced in glitching but I think they'll encounter the same issue regardless

#

The rom itself is easy enough to dump, in fact I think it's been dumped already

#

the main issue is getting the STM32 firmware

#

that's not surprising, the rom pokes registers that don't exist in normal genesis carts

#

mostly because it's missing the additional hardware. like the stm32

#

I think they also added memory? not sure

#

Oh! yeah, they have a custom mapper chip

#

ie. the rom is mapped to specific memory locations

#

depending on what is accessed

#

because the rom is larger than the max rom addresses on Megadrive

#

I think super street fighter 2 also did something like this

#

maybe pier solar as well

#

the mapper has to be implemented

#

one main issue is that the cart has enough custom hardware that it could be argued paprium isn't really a Megadrive rom XD

#

kinda like Virtua racing isn't what I would call purely a Megadrive rom either

glass shale
#

What would be the result of an emulator running the rom properly (custom mapper implemented) but without the STM32 emulation part? No sound at all? Other glitches?

narrow jasper
#

I think you can disable the stm32 sound in the game options

glass shale
#

Whoa

narrow jasper
#

no idea if it would work without the stm32 though

glass shale
#

So the rom would be fully playable then

plain quiver
#

I think I remember that video with the game running on a MAME build, without the STM32 ound.

glass shale
#

Hopefully the full rom is in the wild soon so emulator developers can implement the mapper

narrow jasper
#

yes, they repammed the rom using a custom build of the genesis emulator afaik

#

that's how it ran on mame

glass shale
#

Not sure if EkeEke is still active but he could implement the mapper for it inside GenPlusGX in a heartbeat

#

Provided he has the rom

narrow jasper
#

that's probably the way it will work for a while then. I don't see Sorg implementing a hd audio decoder in HPS just for paprium

glass shale
narrow jasper
#

btw you can probably patch the rom to not use the STM32 at all and get hd audio from some other source

#

I don't recall the audio files being encrypted

glass shale
narrow jasper
#

so dumping the STM32 rom is optional unless you want a true 1:1 replication of the cart

glass shale
#

Final ROM will probably contain some patches for emulators to run it properly

plain quiver
#

For the time being, we have The Cursed Knight, Demons of Asteborg and Astebros to play.
I've paid for the Paprium card eons ago, but never received it, so I'm playing it when a friend goes with their card + a Wondermega on retro conventions.

narrow jasper
#

you could also just also write a stm32 hd audio decoder or equivalent or something that reuses the same registers/API

glass shale
narrow jasper
#

and not having to patch the rom

plain quiver
#

And his card is rattling like nothing else.
I need to see the card once more, open it and reglue the whole heatsink inside.

#

Sorry, 'heatsink'.

#

We know. 😉

#

Personal opinion, PS Vita researches are more important than Paprium.

#

😏

glass shale
#

For that video or the rom? O_O

#

This is found to be a fake

#

Yep, but there are a couple of evidences there that sustain the theory hehe

pale plover
#

I am really liking this new core so far, really my main complaints are just the lack of any "turbo" option like the old core and no EEPROM saving.

#

I liked using turbo for specific games like Road Rash II and Panorama Cotton to make them run smoother.

maybe you should play good games

#

Oh wait those are good games!! linknoo

#

does anyone know if the megadrive+ w/ the improved audio works on the new megadrive core?

round bobcat
#

will the new core replace the old one? or will it appear with update all?

Does anyone know what kind of differences I should expect in this new core? Anything that works obviously better than before?

I think that when the functions we had and the bugs that are missing and will still appear, it will replace the old core well

do windows links work for mister?

or is that a hard link?

maybe whoever wrote the oriignal message can edit to add that so it's together

Sounds great 😊

Also could use some text about how to identify your storage directory if you are using external or network storage

#

It was discussed briefly before

glass shale
#

Dinierto’s steps are for Linux (RetroNAS). Windows commands in there are completely out of scope?

brittle geyser
glass shale
#

Not sure you can create a symlink in windows from a samba share?

#

If that’s possible it would be even simpler

Super simple

#

What's Retronas?

A rasp pi based NAS?

So errors galore running the VDP test rom on the new core for both SMS and Megadrive tests

glass shale
old sierra
#

I ran these tests in the past, let me dig up the ticket

glass shale
#

Check against real hw would be super helpful!

old sierra
#

Attached is the results for the SMS with screenshots on the old core, a PAL MS system, and the Mega SG

glass shale
#

Does it pass all tests on a real mega drive or genesis?

old sierra
#

Here are the SMS results on the new core, note it doesn't even display the test screens correctly

#

I am pretty sure all tests pass fine on OG Megadrives, looks like back then I only tested the SMS. @carmine pine did you ever test these on an actual Genesis?

#

These are the test options incidentally

#

As an aside the recent FW update for the Mega SG SMS core apparently fixed the one fail that core did (SG failed one MiSTer passed, and MiSTer failed two the SG passed)

#

You can download screen shots for the results on the tickets above

@warm falcon

brittle geyser

#

-because the test is a .sms file I can't load it on the old Genesis core

glass shale
#

I think a test on a real MD/Genesis is more important at this point

old sierra
#

Does anyone have the gear handy?

heady harness
warm falcon
#

SMS tests fail same way as on real MD

#

MD tests are weird. on md2va0 pal with toshiba z80 and md2va4 ntsc with integrated yamaha z80 they pass, while on md1va0 ntsc with zilog nmos z80 number of tests fail. On nuked-md tests related to hcounter timings fail (sometimes only 1 test, sometimes 3 tests)
EDIT: now 3 hcounter tests fail on md2va4
EDIT2: every time I reboot console it shows different results lol
EDIT3: on md2va0 tests fail too now. probably tests are themselves are broken

#

also md palette hangs on nuked-md, run fine on real consoles

glass shale
#

This is great info, @warm falcon ! Thank you!

#

Can’t seem load games with a set name variant of the MegaDrive core using mgl.

#

Works without issue with the Genesis core. Interesting, I wonder what’s different.

glass shale
#

Maybe something inside the MiSTer framework? I think that’s worth it a github issue so sorg can take a look, @fallow dome

hard silo
#

I’d mention boot.rom as well

#

Cause the new core doesn’t support it

glass shale
#

Isn’t boot.rom the new tmss thingie? It seems to be working here?

harsh iron
#

yes

#

these tests fail in real md

MiSTer can do MSU, but not MD+ currently.

#

But MD+ has a much more active community - doing soundtracks for romhacks even. There's one for Shredder's Re-Revenge, for example. It's really really great.
