@Hypermug; made me aware of the existence of P:M on dolphin so people can play online on their computers, so this thread is to bring everyone who plays this way online and to enlighten people who, like me, didn't know this existed.
This thread shows you how to set it up. The only thing that isn't provided is the NTSC ISO of brawl, which can be torrented through the use of google. It's recommended you buy a gamecube controller USB adapter for the most comfortable of matches.
@raizoo; @KhainiWest; Once i get the adapter i'll be good to go.
Also the online apparently lags if you're not in the same region as your opponent, so post your region info.
