I also have that kinda problem, like the icons are all jumbled up... the only thing is, i use kind of a different Riivolution... but it still works for the hacks... but i cant figure out how to make the vertical CSS work with the Riivolution i have right now.
Have you used a lot of coding hacks in the past? It seemed like i ran into every road block possible while installing this. I use Riivolution, and what I did was copy the .gct in the codes folder and put it into the gecko folder which contains both a "RSBE01.gct" and a "Riivolution.gct", and I basically made both of those files the RSBE01.gct with the new codes. idk if thats what you're supposed to do, and i still have a problem when I go to the training menu (it gives me the beep of death), but I got normal brawl to work correctly doint that.
