HA HA HA. That video made my day! Thanks Jedi... The bongos for A button are too much. That would make an awesome gamecenter episode.
Yeah, I meant I have a gba sp for my son, sorry for the confusion there. I'm going to look for a cheap kirboy pinball cart to see if I can mod the sensor.
Thanks for the mass of ideas guys! I'm getting him warioland 2 and 3 now and will start looking for some of the other suggestions!
