You've probably heard this before but..

I'm new to Brawl modding and I want to add some characters using BrawlEX, Couldn't get that to work.
So I tried to replace a skin.
That didn't work either and gave me the exact same problem: the game freezes right after"intro" cutscene/press start screen.

When it freezes I see the "Select Modes" buttons appear and then freezes.

I have a PAL game and WII U.
I have homebrew installed with Gecko OS and Riivolution (tried both, same problem)
The game works just fine without Gecko OS or Riivolution.
SD card (2GB toshiba)
I put D before folders

root: D.apps,D.codes,D.private,D.riivolution,config.dat
private:\wii\app\RSBP\pf (and pfmenu2)\fighter\falco\Zant skin including new textures for falco. (PAC and PCS)

Any help would be very appreciated!
(I'm dutch so tell me what I wrote wrong.)

EDIT: I fixed it
