I've been using Riivolution to load up all of my textures and the like, I find out about USB Loader GX and I was intrigued at the faster loading times. I knew it used Gecko and I would have to sacrifice Riivolution for it, but the rewards outweigh the drawbacks. I tried using the file replacement code (v3.5.1) and nothing loads. I don't know if I have the wrong filesystem now or what, but it just loads regular brawl.

My files are stored like this:
SD Card:\private\wii\app\RSBE\pf\
And so on and so forth.
Any help will be appreciated and the person to figure this out will get to beta test my KCMM themed stage.
