00001 /*******************************************************
00002  * This main program simulates a multi-game multiplayer
00003  * arcade gaming system. The program allows the player
00004  * to choose from four different games:
00005  *
00006  *  1) Simon
00007  *  2) Super Tic-Tac-Toe (second player, the blue O)
00008  *  3) Pac-Man
00009  *  4) Rock, Paper, Scissors, Lizard, Spock
00010  * 
00011  * All games except Pac-Man communicate with another
00012  * gaming system via an XBee module to simulate
00013  * multiplayer. Pac-Man is multiplayer as well, but the
00014  * characters in the game are controlled using the three
00015  * tactile switches on one board.
