Kid Buu uncompatible with Mewtwo.

[Chuckles]

So I downloaded the new Kid Buu Vertex for Lucario and I have the Mewtwo PSA...is there any way to make it compatible with the PSA.

(The Game freezes on the AAA combo because of the textures.)

you have to edit one of buu's bones in his hand... talk to the creator of mewtwo about it

Nanobuds is right, the Mewtwo PSA uses edited bones, which don't technically exist in Buu. You'd have to rename them appropriately in BrawlBox (compare their bone names side by side and make the appropriate changes).
