Since last week, I'm experiencing a very weird hardware problem with my R4DS + NDS phat: 1. When I boot my NDS, the R4DS card suddenly doesn't get detected anymore and I get the default screen with "No NDS card inserted". All my other official games work perfectly. 2. When I try this R4DS card on the new DS Lite from a friend, it's boots without problem and without delay (tested > 50 times). Now, should I buy a new R4DS card or a new NDS ????
