So basically I have an official Guitar Hero On Tour grip, and I have an R4DS. I have updated my R4DS to v1.18 and downloaded the 3 guitar hero games onto my R4. I then put in the grip, turn the Ds on, try load a game, and it just says, Grip is not inserted, please insert it, turn off DS and try again. I have blown on the contacts, didn't help. Any ideas how to fix this?
