You can test your roms with the PC version of Final Burn Alpha 0.2.97.29 or Retroarch with the 2012 FBA core before creating the CIA to make sure it will work. If the resulting CIA doesn't boot (boots and kicks you out to the 3DS menu without warning) is most likely due to an incompatible romset. The program will detect if the bios is usable and wont let you proceed if the bios is missing or incompatible. Please note for CPS2 you'll need to copy the QSound bios (named 'qsound.zip') in the same folder as this program, it isn't needed for CPS1 games. With this tool you'll be able to make independent retroarch CIAs for your favorite CPS1 and CPS2 (but not CPS3) games using the Final Burn Alpha 2012 (0.2.97.29) CPS1 and CPS2 cores, without having to install retroarch or anything besides the generated CIA.
