Of Brawl+ codes, only a few works with Dolphin's AR. I don't know much of how they work, but from what I read some of them are a different format than the others, which Dolphin can't handle. I have doubts about SD loader codes because simply saving a snapshot to SD crashed the game for me. You could always iso hack (takes lot of time...)
