The best way to run is by MSXPen (www.msxpen.com).
Just paste the content of "asteroid_belt.bas" in "BASIC Code" panel and press "Run" to start emulator.

I've used a tool that I've created (called "inliner") to help me to write this game. I've added the raw file too because it's much better to read and understand how it works.
