Err that idea sounds neat but it's not a big deal for me... I never travel or anything... I'd just use my GBA as a little handheld system at home (which is one reason I don't like the size and such since portability doesn't matter to me, and I wish there was a way to hook it up to a TV like Sega Nomad)... So it would be useless for me unless there were things you could only get in certain versions of the game (GBA or NGC)...
Not to mention paying 50 bucks for a gamecube game and then like 30 bucks or whatever it is for the same game with SNES graphics just so you could play it "on the go" sounds kinda stupid to me..... meh
