"Video game soundtracks have been around for more than three decades, if you count back to the doomp-doomp of Space Invaders. This mash-up video created by Ithaca Audio folds in bits of audio from Tetris, Street Fighter and Sonic next to tracks by David Bowie, Michael Jackson and the old-school Doctor Who theme. And to keep everything tied together thematically, samples are dropped with input from re-wired Nintendo system controllers. A catchy bit of fusion, if you ask me."

This is a video of a live chiptune performance. This video demonstrates one way 8-bit music can be performed by hacking into the hardware.
