Making Chiptune Music using Sonic Pi v2.0

Warning: this might not work on a RaspberryPi yet

I was curious about making retro gaming sounds using Sonic Pi. A couple of months and a lot of Googling later, here's the original Mario Bros theme as it was heard on the NES console.

I'm (just about) old enough to remember rushing home from school to play this game at Philip Boucher's house, sitting cross-legged in front of the TV till my feet got pins and needles. Working out how to recreate it for Sonic Pi was a lot of fun!
