Notes:
Known issues:
* Sound emu isn't perfect - sometimes explosions don't register in Asteroids
* The low background thrust in Lunar Lander isn't emulated
* Asteroids Deluxe and Lunar Lander both toggle the LEDs too frequently to be effectively emulated
* The ERROR message in Asteroids Deluxe self test is related to a pokey problem
