So I tried more systems, so far I got to work the following: NES, SNES, GENESIS (.bin), GBA, GBC, GB, CPS1, CPS2, no luck on NEO GEO, MAME, for Master System and TurboGrafx16 it would not even see the files.
Of course with the systems that worked, not all games worked, for example on CPS2, I could play Alien vs predator, SF Alpha, but none of the Marvel VS series worked, or Xmen Children of the atom.
