The consoles and handhelds of classic systems are easy to test compatibility with but when it comes to arcade systems where variations of ROM sets (and BIOS sets) come into play things start to get dicey. Does anyone know how well the FBA, CPS, and MAME sets play with the Libretro builds based on the same source used for the cores? I really want to play some arcade games on the 3DS but it is tedious to have to (re)build sets and do trial and error with rebooting from hard-freezes each time. NEO GEO is what I am focusing on currently. Links to good dats for CMP or RomCenter would be much appreciated!
