Hello! I have just discovered a glitch that allows you to have a 3DS Theme on all the time without a SD card! Steps! (Obviously first pick a theme) 1. Go to a digital software / Cartridge game 2. Press "Manual" 3. Exit "Manual" 4. (Tricky) Just as it is about to enter the HOME Menu take the SD Card out of the system 5. If done correctly, You should have a theme on your system forever until you insert the SD card again. 6. You can run games (Cartridges and other apps) and once you go to the HOME Menu, The Theme is still there If you insert the SD Card it thinks your taking it out and goes to no theme lol Hopefully you theme lovers use this!!! Glad I was able to find and share this glitch!!!!
