Final-Smash freezes after importing a Model

[RaineFeanaro]

hi guys^^
I'm trying to port the Alatreon from Monster Hunter Tri over Ganons Final-Smash, this boar you know. With Riivolution and PAL the game freezes when Ganon get the Smashball. With the File Replacementcode and NTSC-U the boar is as always. Any Ideas how to fix it?
