well if the FD hacks was a import model texture or anything that change the stage form the replay might desync. Same goes for texture hacks on a character. If it alters the model then it might cause the replay to desync.Yes, I'm pretty sure there was an FD texture hack and maybe a pikachu hack but i don't think so. probably only a FD hack.
and the replay works on my wii just fine so i don't really understand whats wrong , my wii has never been hacked or anything.
I have uploaded the replay again, maybe this time it doesn't desynch I don't know:

maybe you have hacks on yourself?
