How bad is the screen on the orignal GBA? Is it almost unplayable? School starts up next week, and I have like a 5 hour break (I drive back a forth to school) so Im going to have alot of downtime. It would be nice to be able to play some RPG's. But I dont know if I want to dump 80 bucks for a SP. I can pick up a reg. Advance for 30 bucks but is it worth it?
