Hey all, had a quick question that I havn't been able to find an answer to. I know there are issues with single card muliplay with the R4, but how about regular multiplay where everyone has the game. IE if 3 people had retail Mario Kart DS and one had a Rom backup of the game (that they legally own), would they be able to play multiplayer together? Would the backup work for online competition? Basically I don't have an R4 yet, and I'm wondering if I should wait for the G6 DS Real. I'm not too worried about lack of single cart multiplay, so if the R4 can do regular multiplay it seems like a better option... Thank you!
