Guys, can someone help me? I use Riivolution to hack Brawl, I can't seem to get a Custom CSS, I have the files and stuff in the right place, but when I go on Brawl, I go on to the CSS but it shows the original one. I tried this with Gecko OS as well, I have the codes, but still nothing..please help.

Oh and btw when I use GeckoOS and select Brawl, it plays the music for like 2-4 seconds then my Wii makes this continuous loud buzzing sound and freezes, can someone please help me fix this problem.
