sync thing in a gameboy (self audio sync)
this is a gameboy i built for a customer, i was a be reluctant to build it as it uses my sync thing which isn't fully developed yet. but the results were better than i had expected. the gameboy takes the clock signal from LSDJ and uses that to interrupt the audio. this makes a pulsing effect with the audio which is in time with the music
the gameboy was very difficult to build, i was designing it as i built it because the sync thing wasn't finished yet and so i had to add bits as i built it to make it work and i was running out of room. in the end i had to loose the headphone jack and internal speaker
