I bought my friends DS w/ M3 SD for the Slot 2. It has been flashed with flashme. It didn't come with a SD Card so I had to buy one myself. When I put the M3 in the DS without the SD Card it boots just fine, but when I insert the SD Card it just boots to a black screen. If I remember correctly, isn't there supposed to be some boot files on the SD card or something? Right now it's just formatted with noting on it. I've been trying to find a guide on what to do, but have been unsuccessful. I leave for Vacation tomorrow and would love to have this working for the long drive. Can anyone help me? Thanks in advance.
