Ever wanted a deviantART theme on your Nintendo DS? Well if you own an R4 or an M3 DS Simply, you can use deviantDS. This will theme the whole interface.
1. Open your Micro SD card on your computer
2. Open the "_system_" folder
3. Replace all the images in the folder with the ones in the .zip
(If you have never themed your device, just copy the images to the folder)
4. Put your card back in your DS and enjoy!
