Neo CD

ByteThis

I have been trying to get Neo Geo Cd to work. I have the necessary bios files, but I don't know which files to edit and add --subsystem neocd in, and if we need to add a change in the extension of the emulator config to add in .iso and .cue. Any insight would be appreciated.

@bytethis I think NeoGeo CD support has been committed recently in the RetroPie setup script itself (https://github.com/RetroPie/RetroPie-Setup/pull/2413). You need to update the RetroPie-Setup script, then update (or maybe reinstall ?) the lr-fbalpha package, then copy your .iso/.cue files in the arcade, neogeo or fba folders.
As for the necessary BIOS files, see this topic for details.

@mitu Thanks for the reply. I have updated lr-fbalpha package and have the neocdz and neogeo bios files. I tried an .iso along with a .cue file in each of the arcade, neogeo and fba folders but they won't run. It is mentioned here : https://github.com/libretro/fbalpha/issues/4 and here : https://retropie.org.uk/forum/topic/18011/fba-is-not-arcade-only about having to add --subsystem neocd to the command line . This is the only thing I suspect why it the roms won't run.

@bytethis is there any reason to prefer neogeo cd instead of the MVS rom version within fba romset?

as far as i know cd versions where only released for few earlier games but it was generally limited due to small cache and long loading times of the neogeo cd.

@robertvb83 Just something new to learn and experiment with I suppose. Want to see the quality difference of games. I have seen the NeoGeo Cd game list and has some titles that I already have and wanted to play the NeoCD versions. My Retropie setup has seemed to be idle with adding anything new in quite awhile , so thought I would try something different.

@bytethis Can you use the Runcommand launch menu and change the emulator for the NeoGeo CD game to lr-fbalpha-neocd ? I think this is how the command command line gets the -subsystem neocd parameter when running with an .iso or .cue file. If that works, then you can save this emulator for the game.

ByteThis

@mitu I went into Runcommand, but the option for lr-fbalpha-neocd isn't there. Just lr-fbalpha and lr-fbalpha-2012.

@bytethis Can you post your /opt/retropie/configs/arcade/emulators.cfg file ? After updating right now, the contents of the file contains the support for launching NeoGeo CD images

lr-fbalpha = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fbalpha/fbalpha_libretro.so --config /opt/retropie/configs/arcade/retroarch.cfg %ROM%"
lr-mame2003 = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mame2003/mame2003_libretro.so --config /opt/retropie/configs/arcade/retroarch.cfg %ROM%"
advmame = "/opt/retropie/emulators/advmame/bin/advmame %BASENAME%"
default = "lr-fbalpha"
lr-fbalpha-neocd = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fbalpha/fbalpha_libretro.so --subsystem neocd --config /opt/retropie/configs/arcade/retroarch.cfg %ROM%"

and the same for fba

lr-fbalpha = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fbalpha/fbalpha_libretro.so --config /opt/retropie/configs/fba/retroarch.cfg %ROM%"
default = "lr-fbalpha"
lr-fbalpha-neocd = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fbalpha/fbalpha_libretro.so --subsystem neocd --config /opt/retropie/configs/fba/retroarch.cfg %ROM%"

@mitu How do I make the black background for easier reading ? Never had to do it before.

Wiil try again..lol. I put it on pastebin :https://pastebin.com/DTWnxFdL

@bytethis Ok, it's clear your file doesn't contain the correct emulator invocation, but - as I said in the beginning - this was committed recently, so you'd have to run an update for both the RetroPie-Setup script and at least update the lr-fbalphapackage.

ByteThis

@mitu Ok..I updated it 3 days ago first from source..tried it..no go..then update from binary..still no go. I will update from source again. Thankyou for your help..very much appreciated.

mitu

@bytethis You don't need to update from source, the emulator is the same, it's just the support for the NeoGeo CD that was added as a configuration option. Update from binary and you should be fine.

ByteThis

@mitu I updated from binary and still no change. Rom still kicks back to the menu and no option for lr-fbalpha-neocd.

markwkidd

Update RetroPie-Setup, not the emulator.

ByteThis

@markwkidd Retropie Setup is up to date.

mitu

Ok, then try to add the line with the neocd I pasted in the arcade system's emulators.cfg and see if it shows up in the Runcommand launch menu.

ByteThis

@mitu I got it to work. I was trying it on Retropie version 4.2, which I had more space on that sd card for the rom. I forgot I had a brand new sd card with the newest Retropie on it (brain fart ) .I updated the lr-fbalpha and added the rom and bioses and it works. There is an option for lr-fbalpha-neocd in the runcommand menu now . Thanks for all your help man !

Pros :

Better sound in some game
1 exclusive game (Samourai Showdown RPG) which is in japanese but have unofficial translations it seems. Well, from what i heard, it's not a great game.

Cons :

Some sprites/animations are removed here and there in some games
