In Super Smash Brothers Brawl, there is an infinite involving a single banana that Diddy Kong can do.
This is a video showing it alongside setups.
Being a dedicated Diddy Kong main who regularly attends tournaments on a National level, I have this infinite basically mastered. It's tough to set up, so it's not really viable in tournament, but that's the not the point of this thread.

Somehow, some way, the infinite does not work in an emulated copy of Brawl. Not on the American one, not on the Japanese one. Attempting the infinite causes the character hit with the banana while on the ground (After you turn around) to bounce the same direction he initially bounced, instead of going the other way. It's impossible to do, and I don't get it.

Why I don't get it is because...like...HOW can this be an emulation issue? From my understanding, it almost breaks the rules of emulation. Anybody who understands emulation would vouch for this, that it just simply doesn't make sense.

So can anybody cook up a reasonable explanation for why something like this could happen?

Note: One of the reasons this becomes a serious emulation problem is because it seems to be completely altered for even if Diddy hits someone with a banana thrown downwards while turned reverse to the opponent. This means that a maneuver that anyone can perform acts completely backwards to how it does on console.
