I recently bought SSBB again, but I ran into problems with my wii which I solved. However, since Riivolution was not working, I went to Gecko OS. It worked fine with the unrestricted camera code, but it wouldn't work with the File Patch Code.
Some information that might be helpful: Riivolution told me to insert the disc, even thought it was already inserted. My SD card is 2GB and a regular SD card The SD card was not locked while in the wii
EDIT: I forgot to mention that my region was NTSC-U
Solution: Make sure your file in app is named rsb? (? being your region) as I had it named RSBE01.
I'm not sure if this is the right place to ask, (since I am new) but is thier have the common(x).pac files for NTSC-U brawl? The newest link is disabled.
