No need to rename. This is how my /media/fat/games/NEOGEO looks like.

<rbf>_Console/NeoGeo</rbf>
<setname>NeoGeo-CD</setname>
</mistergamedescription>Should I add another line like this? I'm not at home so I can't test it atm.
<mistergamedescription>
<rbf>_Console/NeoGeo</rbf>
<setname>NeoGeo-CD</setname>
<file delay="1" type="s" index="0" path="fat/games/NeoGeo-CD/"/>
</mistergamedescription>I have all the CD games in a folder called NeoGeo-CD in the games directory on the SD card, which is the only storage this mister has. I put each CHD in its own folder.
I was having the same issue with the black screen, your first mgl file looks good. Just make sure you have the BIOS files from https://github.com/Abdess/retroarch_sys ... oGeo%20CD/ in the same directory as the CD images.
I don't know if you need all those files, uni-bioscd.rom seemed the most important, but I went belt and braces and added them all.
Edit a few weeks later:
Turns out the belt and braces approach was a bit much, see the newer posts in this thread for the minimal set of files you need.

Re: Neo Geo CD Core
Same here, I don't get sound during boot animation, but it doesn't bother me. What "bothers" me is that the CDZ and region settings in the unibios don't save, so I have to press select each time and the console reboots itself before I can play. Some way to save it that I'm missing?
If I'm not really interested in the other unibios advantages, could I just use the regular bios and set CDZ and JP reegion in the mister options? I will give it a try.
EDIT: I copied all the bioses in both the NEOGEO folder and the subfolder were I have the CHDs, and the regular bios works, set as region JP (and with sound in the boot animation), which is saved. So it might be a better solution than the unibios if I just want a quick play, unless there is some way to save the unibios settings.

I can confirm that 32MB SDRAM is sufficient for small and large CD games.

Re: Neo Geo CD Core
Thanks, I deleted all config files, and still I don't get the unibios settings saved. Oh well, I'll just configure them each time.
Re: Neo Geo CD Core
Still can't play any games, dont know what is missing
samurai shodown rpg for example, bios shows up, then the cd player menu, I press start as it shows on screen, monkey animation loading, then bios again and I get stuck on cd player menu.

Re: Neo Geo CD Core
Samurai Shodown RPG is a copy protected game. For troubleshooting, you could try another image with the copy protection removed. Search for "Neo Geo CD Copy-Protection Removed Games" on archive.org.

I had no idea about this and since I have the redump verified set from myrient. It's odd because videogame esoterica made a video and usually he informs stuff like this and no mention at all.
Thanks I will try to find the other type.
Re: Neo Geo CD Core
Still no success with samurai shodown rpg, even with the noprotection set. It shows on cd player menu "insert cd" and then nothing.
So far only ironclad runs fine (even with 4x speed it took 4min to go to title screen)

Re: Neo Geo CD Core
I have tried Samurai Spirits RPG, both a CHD I had around and the one on archive.org (cue/bin), and they both have the same problem.
The game loads a screen with an artwork of some characters and a Japanese text (that translates to "this story is fictional"). Then an unibios error screen pops out. If I use the regular bios, the game just resets at that point.
Few other games I tried so far, all worked, but I didn't play more than 5 minutes on any.
Re: Neo Geo CD Core
I had the same problem and selecting "Save Memory Card" in the core menu solved it.

Re: Neo Geo CD Core
You are right, that was the problem, now it is saved, thanks!
Re: Neo Geo CD Core
I had the same thing happen. I changed the mister menu system to CDZ, matching what I set in the unibios, and it went back to normal.
Re: Neo Geo CD Core
Posting here in case Paul may see it. There is an audio issue with Sam Sho RPG.

Re: Neo Geo CD Core
Thanks Paul. I posted a request on Twitter for the author to respond to this thread with those details. If I'm not mistaken he is also the developer of the upcoming English translation, although he verified the issue using an untouched original ISO.
Re: Neo Geo CD Core
Steps to reproduce per Zet-sensei over on Discord:
How I've reproduce the bug - I've taken the Galford route (the blond hair guy on the far right on the selection screen.
Begin your game after 3-4 mins of talking characters.
Go south on the map, near the village and some random battle will begin.
After that battle, the music will go crazy as reported by the other user.
Re: Neo Geo CD Core
On a related note, SSRPG doesn't seem to load at any speed above 2x. Given that, would it be possible to A) have a per-game config which sets this one game to 2x or B) for the core to have a hard code limit of 2x? That way we can leave the main setting on 4x but SSRPG would load at 2x. Just a thought
Re: Neo Geo CD Core
Hey, dev on the SSRPG translation here. I've encountered an audio bug on SSRPG which I can reliably reproduce.
This seems to happen every time you encounter the SECOND random battle in any given area, and does not go away without restarting, and recurs consistently.
https://twitter.com/PricePartDeux/statu ... 85216?s=20
Quickest way to get to this is to start up a game, with Ukyo for the first chapter, or any character for the second chapter. As soon as you can, leave the immediate area to get out to the overworld. Finish one battle (which should have normal audio), then walk around to get into a second one, and then the audio issue occurs.
That's my Twitter, so a reply there will be the quickest way to reach me if there are questions. Thank you, and great work so far on the core.

Re: Neo Geo CD Core
Hey guys, can anyone please confirm what BIOS files are needed in the Neo Geo CD folder to have all the options available, and what each file actually does? I want to make sure the BIOS database has everything we would need in it so they are al grabbed by Update All and I'm confused on what is needed and what the files do.
Thanks!

These are the files needed in the folder
neocd.bin for CD Type:CDZ
top-sp1.bin for CD Type:CD
uni-bioscd.rom for unibios
Re: Neo Geo CD Core
Yes you need that one too but only if you don't have it in the main folder NeoGeo.
No need to have it both on NeoGeo and NeoGeo-CD folder.

Re: Neo Geo CD Core
Not true: I did test it and if you have it in the NeoGeo folder but not in the NeoGeo-CD folder you get messed up graphics.
Now I have to say that I use a mgl for NeoGeo-CD, I did it before the last update to main and it just happened that I chose the NeoGeo-CD name. Could this explain it?
Re: Neo Geo CD Core
@jca maybe because you use mgl to launch it, i use the latest main stock menu.
On my side i only have the 3 files above in the NeoGeo-CD folder.
The rest of the neo geo bios is in the main folder NeoGeo and i have zero issue and can set and launch the core with any setting fine.

Re: Neo Geo CD Core
Thanks. This is the reason I mentioned mgl: when starting the core as NeoGeo it knows about the NeoGeo folder, when starting the core with the mgl the "name" of the core is NeoGeo-CD so it will look into NeoGeo-CD instead of NeoGeo. In order to not duplicate the BIOS I could instead use a symlink. As I am up to date with the core and main there is not much reason of using a mgl.
I did it this way in order not to have to change settings:
For AES I use NeoGeo.
For CD I use NeoGeo-CD.
For MVS I use the unofficial arcade core from Blackwine.
With the new core switching from AES <-> CD does not require a setting change as it is automatically done by loading a ROM or a CD. I think I will drop the mgl.

Re: Neo Geo CD Core
I just double checked:
By starting the NeoGeo core directly without using a mgl the core looks for 000-lo.lo in the NeoGeo folder when the BIOS is set to original.
While I had the BIOS set to original I also tried AES mode and got a Backup Ram Error, This happens only if Memory Card is set to Plugged. This does not happen with UniBIOS.

Re: Neo Geo CD Core
I must say I wasn't sure if the bios were supposed to be in the NeoGeo folder, or in the folder where I have the NeoGeoCD isos (which is just a subfolder in the previous one), so I just went ahead and copied all bioses in both folders.
