Sorry to change the course of this thread in a way. I have compiled a full FBA set compatible with FBA in retropie and I’m wondering if it’s possible to tell some roms to use MAME instead of moving and splitting files etc.

Example is Mikie. This has graphical glitches all over running on FBA but I have a feeling will work ok on MAME. Is there a way for me to add emulators to the FBA list so I can try a version of mame?
