So yesterday I was playing Golden Sun on my DS and I decided to turn on the radio, which was on my desk about half a metre away from where I was sitting. It didn't take me long to notice an unusually loud static noises coming out of the radio. I didn't actually think it would be the DS in the first place so I tried to adjust the radio. In that process my DS dropped to the carpet floor and the static was gone. Then I thought: it must be that the DS has wireless and that's causing the interference. So I searched around for my GBA SP and turned it on, and NO IT WAS EVEN WORSE. With the SP turned on the radio outputs an ear-splitting screech instead. I guess I'll have to stay further away from the radio when I play my Nintendo handhelds.
