*facepalms* Did you bother to read other people's posts?! (I'm betting you used training mode to test...)
EDIT: Woah...I found a bunch of really weird glitches on PS1 while using Marth.
I saved a replay (using reverse PS1 and Near Gold set). When I replayed it, though, it desyched halfway through, meaning the glitches aren't consistent. (The glitch has to deal with the center of the floor, once again.) The glitch at the very beginning would probably happen every time, though.
There are things such as teleporting to death, a wield bump in the floor's center, character glitching out, teleporting onstage, among others.
Here's the replay file if anyone's curious: http://www.mediafire.com/?hzzowi3ztmt
EDIT2: It managed to replay correctly all the way through on my 3rd attempt of replaying it.
I've read all the posts in this thread and I played on VS mode too. Just coz you have 1000+ posts more than I do doesn't mean I'm any less competent than you are.
If my post repeats what others have found than it's a good thing. It means the problem is consistent rather than MK26 getting 5 different bug reports.
