FBA is open source, so if you have enough time and knowledge, you can make it run any neogeo sets you want. The official builds of FBA use the same roms as Nebula, Kawaks, and MAME. Also, FBA is almost as fast as NRX, but has a MUCH better sound core (which is why it's a bit slower) and much fewer bugs. The version the FBA team is going to release next will have an ASM m68000 core, which will speed things up even more
