/*******************************************************************************
Gordon Barlow Design electronic Space Invaders game (unreleased, from patent US4345764)
* COP421 (likely a development chip)
* 36+9 LEDs, 1-bit sound
This game is presumedly unreleased. The title is unknown, the patent simply
names it "Hand-held electronic game". There is no mass-manufacture company
assigned to it either. The game seems unfinished(no scorekeeping, some bugs),
and the design is very complex. Player ship and bullets are on a moving "wand",
a 2-way mirror makes it appear on the same plane as the enemies and barriers.
