I know dumb question but can I get games like super smash bros brawl to use a GC controller? if so how I already have an adapter I just do not know how to get it to work with it unless I ran the script wrong?
There's currently no way to do that with Wii VC injection.
A user has recently figured out a way to get the GCN adapter working when playing games over disc, but it breaks when loading games via USB or SD. (people are working on getting it to work for backups though)
