Okay, I have two Yoshi .pac files - one is a moveset hack, and the other is one that plasters Yoshi's eggs with the  :af: all over it.
What I want to know is if I can have both in the game at once - they're both FitYoshi.pac, so would they kill each other?

(considering that I'm new here, this might be the wrong place for this, but it seems like it'd be the right area for it, bear with me if I'm wrong)

Okay, here's  a problem I've been having for a while.  Whenever I want to download a texture of some sort, there'll be two files to be downloaded - fitXXXXX.pcs or fitXXXXX.pac. Nothing out of the ordinary there, I've seen them for stage textures, movesets and whatnot. The thing is, the game will usually crash after a match is over when I have a character texture enabled upon returning to character select after a match is over.
Now, oftentimes when I get to the download link of a texture, there'll be both the pcs file and the pac file. Am I supposed to place both files in the folder, or is there a specific file to go in one area?
