Okay, so I just got my M3 Pro over the weekend. I installed it correctly, and put the latest Firmware on the DS. It has been working pretty well until just recently. When I turn on the DS, I go and try to play a game, and then the system freezes. So I turn off the DS, and then turn it back on again. This time, after it passes the health and safety warning, It shows that the Passcard 3 is in the DS slot, but it doesn't show the M3 in the GBA slot. I turn the system off, pull out the M3, and blow in the system and M3. Then when I turn it on, it sometimes shows it, but it still doesn't work. Can anyone help me with this.
I just looked, and in the White GBA cart that I put it in, it is kind of at an angle. So I put it in one of the other GBA carts provided with the M3. They seem to be pretty even. I'll try this out and see if it works.
