I have an m3 simply that is using R4 firmware (Which has worked just fine until now), and plays every game that I've tried so far with no problem. I recently downloaded Monster Lab and Sonic Chronicles, and both of them have the same error message: "The save data could not be accessed. Please turn off power and reinsert the DS." I have tried re-downloading them both and re-extracting them both, and it won't stop. Any ideas what's wrong?
