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 !
