8814-881f sprites - 6 pairs: Y position and color
8034-880c radar car indicators x position
8834-883c radar car indicators y position
a004-a00c radar car indicators color and x position MSB
a080 watchdog reset
a105 sound voice 1 waveform (nibble)
a111-a113 sound voice 1 frequency (nibble)
a115 sound voice 1 volume (nibble)
