How to fit a USB drive in to an old Game boy advanced cartridge. For looks...
Step 1: Gather Required Materials
Pretty basic. You need:
1. Small screwdriver, it uses a triangle head but a small enough Philips or Flathead will work with a little pressure.
2. Gameboy cartridge, DONT USE A POKEMON GAME, its a waste :)
3. Razor blade, you can use a dremel, but I dont have one because im poor :/
4. and finally, A USB drive. Can be any size, i used a 2 GB
