Using An Oscillator To Modify Pitch Of Gameboy

In this video from Look Mum No Computer, we learn how the CPU of an old Gameboy can be used as a host for an oscillator signal, allowing the Gameboys internal sounds to be modified.

From information he provides in the video’s description:

So its simple! you solder a wire from the oscillator out straight to one leg of the timing crystal of the #gameboy, and you can override that and use the oscillator to clock the gameboys CPU! meaning you can adjust the pitch!

If you’re crossing your fingers for having your own one of these modified Gameboy machines, LMNC has created a free giveaway contest on his Patreon page. You can also check out his Youtube channel for more crazy synth videos.
