You need the fighter files for the characters (FitChar.pac, FitChar00.pac, etc.). You'll need either the CSSRoster.dat or custom css code. You also need a config.dat with AXNextFrame in the root.
Okay. I found a config.dat file in the root. I also found the Custom CSS Code on Gecko Codes, but the last two lines have this:
06680DE0 000000YY
ZZZZZZZZ ZZZZZZZZ
Not sure what to input for this.

I forgot to specify what happens. I replaced the entire pf folder in Project M's Launcher and the pf folder that's used for Gecko. When I try to use the Project M Launcher (and I have the SDHC extension code and the file patch code), it just goes back to the Wii Menu! What am I doing wrong!!?
