Hey guys I am just learning about brawl hacking and had a question about the hacks for characters that overwrite other ones.  I was looking to replace Wario with Mewtwo (I know there is one for him) but I found one that does not have any glitches in it for peach.  Im wondering if I can just rename the files and put them in peach's since I assume they are completely overwriting the original characters mechanics. Another example would be a Buu that replaces Lucario's file , but again I rather not replace lucario.  The Wario hack that would be replacing him but not sure if this one is better then peach's.

Also my second question was is there a wat to add more options to the color list such as just simply putting more files example being FitLink06.pac but ordinarily going only to FitLink05.pac.

Thanks for you help guys!
