This is my tune I made on real GameBoy (DMG-01 model) using Little Sound DJ Tracker. Sound was recorded directly from GameBoy with no postmodifications. To create this visualization I wrote a simple app to display wave of each GameBoy channel. I think it is quite interesting to see shape of sound and I hope you like it too, both video and music. btw that gameboy on the photo is mine :)

Also please note this is a remix of song Lovely Feelings from game Rock'n'Roll, made by Chris Huelsbeck.
