Hi,
I am also on windows/retroarch and it looks like this...
executable x:\RetroArch\retroarch.exe
args -f -L X:\Retroarch\cores\fbneo_libretro.dll "[romfilename]"
rompath x:\RetroArch\Games\FBNeo - Arcade Games\ROMS\
romext .zip;.7z
system Arcade
import_extras x:\RetroArch\Games\MAME\Catver.ini;x:\RetroArch\Games\FBNeo - Arcade Games\listxml.xml
artwork flyer x:\RetroArch\Games\MAME\flyers
artwork marquee x:\RetroArch\Games\MAME\marquees
artwork snap x:\RetroArch\Games\MAME\snap;x:\RetroArch\Games\MAME\video
artwork wheel x:\RetroArch\Games\MAME\wheel
I have mame installed too...you have to change the folders...
The standalone version of FBAlpha creates the latest listxml.dat for the core v0.2.97.44... think I have changed the ending to .xml to get it accepted in AM...
...or download I think I had also a github link for FBNeo...
...if you have one try to change to ending from .dat to .xml
Would have added my listxml.xml but its to large, sorry...
...I would set filter like no clones etc later in AM....
