I only just now realized, thanks to World 7: Saturn - Easy, that these are clearly not the same versions of the game. @Veuceu's game has only 2 stars for each level when completed whereas mine has 3 and not only that, but some of the levels have a different amount of stars to collect. I don't know how many versions there are but I'm pretty sure I've seen another one somewhere around here recently, too.

If someone wants to help me try to figure this out and start a list of runs that need to be catalogued, let me know. I'm also not sure of what to even call the versions. The game says what version it is on the main menu screen, so I'll just have to have people tell me what version they're using for their runs, and I'll just make sub categories for it. It can't be variables since some of the levels are genuinely different.
