How to add manually an emulator to retropie?

geese howard

i've created fbneo folder with fbneo compiled inside (source from https://github.com/finalburnneo/FBNeo), used command :
"my-emulator="/full/path/to/emulator/program %ROM%", however retropie returns to gamelist without load.

What i´m doing wrong?

FBneo is already included in RetroPie - the libretro core (lr-fbneo) and it's installed by default. Any reason you want to run the standalone emulator ?
If you run the command manually, outside of EmulationStation, is it running ok ?

@mitu version 1.0.0.2 has newly emulated systems, like sega's system 32, not supported by retroarch version.
I get the error log:

Parameters:
Executing: /opt/retropie/emulators/fbneo/fbneo "/home/pi/RetroPie/roms/fbneo/ga2.zip"
/home/pi/RetroPie/roms/fbneo/ga2.zip is not supported by FB Alpha

Is there a way to edit the gamelist?
Arcade Golden axe revenge is supported now.

Not sure where you went wrong with your setup, but the libretro port is in sync with standalone, and support sega system32. Maybe try running retropie_setup.sh and update lr-FBNeo from sources ?

@barbudreadmon here shows v02.9.7.44 (wip) after update from sources, however doesnt work.

@geese-howard Add more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

Enable verbose logging when running the game and then post the resulting /dev/shm/runcommand.log on pastebin.com. Make sure your have the correct ROMset.

Well, as i said, not sure what's wrong with your setup. I'm just stating the fact that you are totally wrong about the fact the libretro port is "late", i update it a few hours after every standalone updates.

I have 1 guess though : your retropie_setup.sh script is probably very old, and maybe building lr-FBNeo from source is failing because of that.

@mitu i posted the log above. Here is again:

"Parameters:
Executing: /opt/retropie/emulators/fbneo/fbneo "/home/pi/RetroPie/roms/fbneo/ga2.zip"
/home/pi/RetroPie/roms/fbneo/ga2.zip is not supported by FB Alpha"

@geese-howard the log you posted is from your emulator entry.
Post the log when running the game with lr-fbneo, make sure you've enabled verbose logging.
And also https://retropie.org.uk/forum/topic/3/read-this-first.

@barbudreadmon i get latest retropie version...
I ll try to run retropie_setup.sh now to see.

Also, your issue here is that standalone FBNeo expects the rom folder to be set in its config file, and the rom file to be called by its basename on command line, meaning the proper command line here should be /opt/retropie/emulators/fbneo/fbneo ga2. I wouldn't recommend using that port though, afaik it's very incomplete and you can't do basic stuff like mapping a controller.

@barbudreadmon ok, i ll try to update according https://github.com/RetroPie/RetroPie-Setup

it works, however a had a poor performance in system32 games. it runs ok in mame 2003 with some glitches...

Is it a known issue?

Raspberry pi3+

FBNeo based its emulation on current MAME for those games, not on 18 years old one. If you are fine with all its glitches then use mame2003, otherwise if you want less glitches you'll have to upgrade your hardware (note that there are still issues even with modern code). Also, i believe even the pi4 is still a bit too weak for sega s32 without a good overclock and some frameskip.

@barbudreadmon ok, thanks for faster reply.
