I have the M3 DS Real today, so I put the system and some games on it and it worked perfectly, then I plugged it again and put some other games, then, again I put the USB and my computer was unable to read it, it didn't appeared, I did everything and nothing. What is the problem with my USB. Also a little question: When I checked my games they were all right but over every game there was a copy of it but it had 0 MB, I don't want that duplicate, Thanks!
Every game or rom u install and try loading up with add a save file with the same name as the rom. So it might just be a save file that u are seeing. I believe the save file with stay on your memory card even after u delect the rom to it so if u don't want or need the save file then u need to delect it yourself. Also, about the usb thing, The usb reader that came with the M3 DS real isn't that great. Mine broke down after a few use and so I went out and brought another usb reader for a few buck and it working fine now.
