ok first of all im sorry that im posting this here but the M3 Simply is the same thing as the R4 right? well i have an M3 Simply (new model without the spring), a SanDisk 2GB microSD formatted in FAT32 and the newest firmware. sometimes (really rare) the games start to freeze and i have to reset my DS. then i "fix" it, by blowing on the cart and in the slot1. it works than, but its really frustrating when im playing Phoenix Wright and have to play through the last 10 minutes _again_ i dont want to replace it at the shop i brought it because it was really a pain in the ass to get that card (ya'll know its sold out most of the time, especially here in japan). so is there a way to fix it infinitely?
