Good morning all !

I have a big problem with the fbneo libretro core for NeoGeo & NeoGeo CD games with RetroArch. Under Attract Mode for NeoGeo games I use this:

Code: [Select]
executable           c:\attract\emulators\retroarch\retroarch.exe
args                 -L c:\attract\emulators\retroarch\cores\fbneo_libretro.dll "[romfilename]"
rompath              c:\attract\games\neogeo
romext               .zip

Unfortunately nothing happens... on the other hand, from the command line (Windows console) NeoGeo games launch without problem like this:

Code: [Select]
c:
cd c:\attract\emulators\retroarch\
retroarch.exe -L c:\attract\emulators\retroarch\cores\fbneo_libretro.dll "c:\attract\games\neogeo\roboarmy.zip"

Same for NeoGeo CD games under Attract Mode if I use these arguments nothing happens:

Code: [Select]
executable           c:\attract\emulators\retroarch\retroarch.exe
args                 -L c:\attract\emulators\retroarch\cores\fbneo_libretro.dll --subsystem neocd "[romfilename]"
rompath              c:\attract\games\neogeo cd
romext               .cue

By cons command line with CMD (Windows console) if I use the same arguments it works why ???

Code: [Select]
c:
cd c:\attract\emulators\retroarch\
retroarch.exe -L c:\attract\emulators\retroarch\cores\fbneo_libretro.dll --subsystem neocd "c:\attract\games\neogeo cd\pulstar.cue"

I have the same problem for mame libretro... how to proceed please ?

Greetings !

do not use the FBA core...

use the core made for the NEO-GEO CD itself..works fine..I use it myself

make sure the your bios is in your system folder they you have set....and that it is in the folder "neocd" (ex. /bios/neocd.)

your AM config is fine..just change the core.. neocd_libretro.dll

People want life easy..then complain about it

Hello & thank you for your help!

I have three problems:

1. The core neocd_libretro works well with Attract Mode but I no longer have this screen before loading a game:



I think this is due to some missing BIOS files (see documentation here) because I cannot find the following files:

neocd_f.rom
neocd_sf.rom
neocd_t.rom
neocd_st.rom
neocd_z.rom
neocd_sz.rom


2. The core neocd_libretro does not support NeoGeo cartridge games...

3. I have the same problem when launching MAME games with the core mame_libretro.

Greetings !

Hello !

Simply because I want to use a single emulator for all Attract Mode & because it has a lot of interesting options :)

RetroArch is not an emulator, nor is it a frontend. It’s mission statement on their website is confusing. It bundles multiple emulators into „cores“  and shares some libraries as well as configurations.

Open any game through neocd and go to options and turn Skip cd loading to on then restart the game. Thats is for point 1.

I know it well but for Nintendo SEGA or SONY consoles it was never a problem... & especially what I don't understand why RetroArch works very well in command line but not with Attract Mode ???
