I'm having a problem with my R4 at the moment. When i put it into my DS, and switch my DS on, it doesn't recognise it at all. Tried removing the card and reinserting, tried the old gameboy trick of blowing on the contacts, but nothing works. I've even tried my R4 in my brother's DS lite, which works, and my brother's R4 in my DS, which also works. Actual DS games work, so i don't have a clue what's wrong. anyone got any magic ideas? incase anyone asks, it's a DS phat, and an original R4.
