I got a hold of an M3 Simply, and it had 48 games loaded on it already with a 2gig card. I didn't want a lot of the games, so I plugged in my card reader, deleted some, put it back in my ds and they were all still listed. I clicked on one that I had deleted and it loaded in, so I was a little confused but I put it back in my card reader, reformatted the drive, and downloaded Wood, which according to research works with the M3 simply. I put that back in the ds, and when it loads in it's back to the same 48 games! I'm a bit lost, it was my understand that you could add/remove whatever you wanted on these drives. Am I doing something wrong or is the M3 simply broken?
