I have had this "problem" for years.
Every time I want to play a game from TOSEC library, I have different dumps of a game, and I don't know which one I should choose. Any of them seems to run, but I don't know the differences between them.
E.g.: Dave Mirra
- Dave Mirra Freestyle BMX v1.001 (2000)(Acclaim)(US)[!][0K055A, B, D, E]
- Dave Mirra Freestyle BMX v1.001 (2000)(Acclaim)(US)[!][10S]
NFL 2K
- NFL 2K v1.007 (1999)(Sega)(US)[!][9S]
- NFL 2K v1.007 (1999)(Sega)(US)[!][10S]
- NFL 2K v1.007 (1999)(Sega)(US)[!][13S]
- NFL 2K v1.007 (1999)(Sega)(US)[!][MT B08, B13, B17, B19, B20]
It's absolutely crazy. It also happens with Saturn games.
Does anyone knows what those suffixes mean, and which one is "the better" to play? Thanks.
