The Game/Fast Download Switch is on SW2 d13, which is at Connector J4 pin 4.

After a Reset, if the game is not in Self-Test:
	
	When J4 pin 4 is left high, the program will go to the Game;

	When J4 pin 4 is grounded, the program will go to the Fast Download
	code, which currently resides in the Self-Test EPROMs.
