I don't know. I have a confirmed rev 01 though, as I dumped it to check. Now that we already have rev 00 dumped, it doesn't really matter if someone has rev 00 or not, unless they want to say "I've got rev 00". So far there are two ways to tell from a lone S2 cart if you have rev 00 - either look at the CNZ1 signpost, or look at the "Executive Supporters" page of the credits and see if you see "Tohmas Kalinske". If it's spelled correctly then it's rev 01, if it's spelled the way I spelled it then it's rev 00. And of course, there's always BMF's method that uses S2, S&K, and a Game Genie. That method can also detect rev 02, and I believe that the Super Sonic bug is no longer an accurate metric to determine whether it's rev 02 or not.
Another way to check, is when you are in HTZ act 2 jump on the ledge, the one at the beggining before you go into the cave, and try to go through the loop you shouldn't be able to go through. Also, put on debug mode and look for the 'Tails' Block in all the levels.
I'm aware that this is a hugeass bump, but this is in the archives and what I have to say is relevant, so meh. What I find particularly amusing about this is that it isn't a bug fix, it's a bug causer - the removal of the mappings test is what causes the game to freeze when you place an object in debug mode right after death I just tried it out in Betas 7, 8, REV00 and REV01, and REV01's the only one which freezes. What I find even weirder is that they didn't bother fixing it for S3K either, it just sorta auto-fixed itself because the stack pointer entry was left as blank in the vector table and loaded later on, which masks the bug.
I didn't feel like reading every single reply, but from what I saw, nobody mentioned the Wing Fortress thing. You didn't know why they changed the Y position. I'll tell you -- you can hit the star posts multiple times, and I think it also has trouble saving your position. Experiment with it a little bit and you'll see what I'm talking about. It's the same problem I had in my Coastal Valley hack. EDIT: I didn't know how old this way until just now. Someone must have bumped it before me or something.
