This is a list of rom codes – those weird letters found at the end of rom file names and what they all mean.
[a] Alternate – This is an alternative version of a rom, for example when multiple rips exist or to include bug fixes.
[b] Bad Dump – Normally a bad rom, though not necessarily unplayable. Often caused when dumping the rom but possibly occurred when storing or transferring it.
[f] Fixed – Generally fixed to run better in emulators.
[h] Hack – Often a hacked rom is one where a release group may have added their own intro/splash screen.
[o] Overdump – This is a rom which has extra data which was not in the original game and is generally removed by the time you’re able to download it.
[t] Trained – A trainer, just like trainers for PC games, includes special code, allowing gamers to cheat or get extra features not in the original game.
[T] Translation – As is suggested, this is a translated version of a rom.
