    Hi guys, I don't know if this has been discussed before, but I haven't noticed it before. Found it by accident when retroarch scanned my library and booted the wrong file.

    This rom is listed as a 'bad dump' of Sonic 3, presumably listed as final. However a lot of Sonic's sprites are from Sonic 2? This isn't listed as a hack or a beta. Where did this rom come from?

    The one in question is: Sonic The Hedgehog 3 (U) [b3].gen, and the filedate is listed 29/10/2000 !

    Trapped in my own thoughts.
    Two stageplays, a screenplay, and an album
    It's probably a mislabeled hack. GoodTools sets are by no means perfect I just gave it a quick test, and though I didn't play the whole thing or give it anything resembling an in-depth examination, it didn't look like a proto or anything. Everything I saw other than a few of Sonic's sprites was, as far as I could tell, just the final game.

    I would be very surprised if this turned out to be a proto sitting under our noses for decades.

    Stranger things have happened, but I wasn't sure either way. I thought I'd better bring it up for someone to compare as I don't have the tools or experience to do a binary diff.

    I checked out the ROM myself. I was greeted with an "incorrect checksum" message and Sonic 2 sprites that are a bit different from the actual Sonic 2 sprites used in the prototype.

    Yeah, it's just a hack.

    Did the proto sonic 2 sprites in sonic 3 have a modified sprite set to use sonic 3s pallette similiar to how tails is?

    Nah, far as I can tell, even Tails is unmodified aside from being forced into a new palette: only true difference is Sonic loses a middle shade.
