If you have an old broken Gameboy lying around why not make good use of it? Aaron Myradon decided to create the “Mouseboy”, a fully functional optical Gameboy mouse. The “A” and “B” keys act as the right/left click mouse buttons. More pics after the jump along with a short summary of how he did it (click images for full-sized versions).

First, the circuit boards/internals were removed from both Gamboy and optical mouse.

Next, he hollowed out the Gameboy’s battery pack using a rotary tool, making room for the new circuit board.
