I tried doing that in Pearl Version, where the framerate is just shy of being half as fast as Gen III. O_O Needless to say that I gave up by the time I hit 7 badges. XD
My Hitmonlee is level 64, and I'm running through all the games in chronological order in anticipation of BW's release. (By chronological, I mean FireRed->Emerald->HeartGold->Platinum->Black). I was gonna toss Colosseum and XD in the mix, but since I only own XD, it would've been pointless. :P
