Circuit-Bent Sega Genesis
This project was delightfully simple, but had great results. The goal is to simply add some switches with which the YM2612 synthesizer chip can be manipulated to make funky sound (and hopefully pleasant too!)
All I did was add a few switches that allow me to make a few of the eight data lines going to the YM2612 open (I.E. nothing connected), causing data sent to it to be truncated and/or corrupted.
Here are two videos of the results:
This one has the same principle applied, but with the Video RAM, producing the fun graphics.
A high quality audio recording of me playing around with Sonic the Hedgehog can be found here:
