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?
are you sure you can use wood firmware on your m3 card, have you also tried the kernel on m3 official site.
