Abstract for group TupacMan

TupacMan is a two-player Pac-Man style arcade game.  We plan to use
the VGA output of the Altera board to present the game's graphics.
Images will be initialized in hardware and sprite movement done in
software.  The software will also control game logic.  We plan to use
the board's sound output to produce simple ``Atari style'' sound
effects.  If feasible, players will play the game using an NES
controller.  Otherwise, we will employ a USB controller or keyboard.
