I have been using FBA (not PiFBA through RetroArch actually; check the ES_systems.cfg, there are two options) and getting some light ROMs to work.
Can you show us your ES_systems.cfg file content regarding NeoGeo and FBA?

Also, right after you fail to execute a ROM, when it takes you back to the frontend, press F4 to get out to the command line and check what was printed out just before. It might help us in determining what is the issue.
