1. Open up the "*microsd card*/_iMenu/_images/Background Skins" folder and browse the different skins

2. In order to choose a skin, copy the "top_bk.bmp" and "lower_bk.bmp" of the skin you want

3. Place those 2 files into "*microsd card*/_iMenu/_images"

4. Allow them to overwrite (do not worry, all of them are saved in the Background Skins folder)

5. Start up your DSTwo and you should see your new skin. If you wish to choose another skin, just redo steps 1-4.
