If I can get something proper, I will open a pull request for it. I am going to try to use that script to generate a new dat for FB Alpha. Copy your Neo-Geo roms over to the neogeo folder and reboot like before to see them. I can only assume, at this point, that the fba-split metadata was generated from an incorrect romset or that there is a bug in the FBA_dat_gen.py script. Find a Neo-Geo romset (don't use the MAME one, use 0.2.97.39 FBA thank you /u/dankcushions) Find the Neo Geo bios (neogeo.zip file, should be in the romset), put it in the neogeo rom folder. In fact, the size for sfiii3n.zip in the fba-split metadat is way too small. This version features mostly localisation fixes, kindly reported by Benjamin Siskoo. If you compare that to the entry in the fba-split metadat (see my first comment in this thread), you'll notice that it doesn't match. Topic: FB Alpha 0.2.97.0.17 Release (Read 1870 times). and then there was a Roms folder as well. In that FB Alpha v0.2.97.39 roms folder there were different folders based on different consoles, Coleco, TG16, Gamegear, etc.
