I heard some guys under some videos saying that Xiahs 2nd place in 16 Star is spliced. Is that true?

whatever you heard is most likely false

No.

There were two runs in like 200X that were spliced. They looked like Xiah's capture card quality, i don't know if those runs were his tho (probably not). That's probably what the people were thinking when they told you.

SeemsGood

@GhostT12547 good logic

but that record was done live?

There is nothing to suggest Xiah ever cheated any of his runs. If you wanna know more about cheating in sm64 speedrunning history look up any of the million youtube videos about it. Locking this thread to avoid confusion.
