100% C-64 with mostly electro/acid/funk kind of music.

The audio is recordings of one song played on an old and a new SID-chip, panned left and right.
There's also dynamic remixes of the songs, and synchronized PETSCII-visuals, on a C64 disk image that comes with the download. (or on a floppy if you're lucky enough to find it on e.g bleep.com)
