Okay, my Super Mario Bros 3 rom on NES seems to be an odd one, and I was wondering if anybody knows what version of SMB3 it is, if it's a hack or a beta or just corrupted. If anybody recognizes these "symptoms", I'd be quite interested in knowing what's going on. My rom seemed just fine at first, playing through stage 1-1 as normal. About 1/3 of the way through 1-2, however, and I noticed that things were drastically different from how I remembered the game (flying buzzy beetles, no p-switch underneath a pipe with a pirhana plant, etc), but it seemed recognizable again at the end of the level. I noticed some inconsistancies on the world 1 map when I checked, after having seen 1-2. 1-3 through 1-fortress were just as I recalled. 1-5 was pretty much the same but with a small chunk of the level missing and a few extra pipes at the end. 1-6 was nothing at all like I remembered, with a horrendously screwy layout and some stupid hard jumps. I seem to recall the airship being as it should be, but I was so disoriented after 1-6 that I wouldn't have noticed any oddities. I quit before starting world 2, because I got bored.
