@mrnoholster what happened is you updated fb-neo which requires a new rom set. The old roms are not for newer versions.
FYI. Updating arcade emulators to newer versions is risky as there is no guarantee that the update will work with your roms. Don’t update them if you have a working set of games. Most roms may be fine in if you just go up to the next update, but if you keep updating, there will reach a point where fewer and fewer roms run.
