    Could you be more specific?

    As there can be several reasons. Different regions like Pal/NTSC. Different scene release groups. Different updated/versions of games etc..

    Can't say I remember roms named Set 1-2-3 before, but Rev is super common. It's short for revision. Modern games get patches, if older games needed some sort of change, they'd push out a revised version of the game with the next printing. Usually there's little to no documentation about what the revision does, unless you're looking at something huge like Zelda Ocarina of Time. Here, for fun look at what people discovered about Ocarina of Time:

    Thanks for the reply! If you look at the MAME roms on this site, you can scroll down on any of the letters and you will see a lot that say for example: Tron (set 1), Tron (set 2). Not saying Tron has this, just an example.

    Oh yeah, I've never personally toyed with MAME. So I'm not familiar with whatever they're doing there. But I'd guess it's probably just about the same as revisions.

    They might be dumps from different boards maybe?

    Yeah, and maybe boards don't have version numbers, so it's just a guess for which version is better/worse?

    I have seen lazy labeling in the past where set 1 and 2 etc. are actually still revisions.

    Unless it's possibly split archives he's seen and just isn't quite expressing it correctly

    What are split archives? Do I extract each one?

    There are also bad dumps(ROMs that were not properly extracted from the original cartridge).
