Where to buy If you do not yet have an M3 DS Simply you can purchase it from one of the following stores: Digimartz Divineo ModChipStore kicktrading winsunx The M3 DS Simply comes with the device itself, a replacement shell in white, a MicroSD reader/writer, a CD with some software on it and a small case for holding the M3 and replacement shell. UPDATE: Apparently the new batch of M3 DS Simply do NOT come with the replacement white shell - I can now confirm this is true. MicroSD Card The only other thing you will need to buy is a MicroSD card (aka Transflash) these can be bought from most online electronics stores, or eBay. They currently go up to 2GB in size, what size you get is up to you, but I would recommend 256MB as a minimum. Formatting Now you have everything you need to first prepare the MicroSD card for use in the M3. So start by plugging the MicroSD into the card reader and connect the card reader to your computer. Ready! Your M3 is now ready to play backed up NDS games and run Moonshell (to play videos, MP3’s and view pictures) so you can now drag and drop any games/homebrew/MP3’s/pictures you want to play/watch on your DS. Files can go anywhere, but I usually ue seperate folders, such as Games/Videos/Music etc.
