THE SW / ESB KIT INSTALLS ON ANY ATARI STAR WARS ARCADE BOARD SET AND ALLOWS THE USER TO PLAY EITHER STAR WARS OR EMPIRE STRIKES BACK BY PRESSING THE LEFT THUMB BUTTON THEN RIGHT THUMB BUTTON ON THE CONTROL YOKE.
Pretty easy to install, arrived quick
Does the game need to be in Coin up mode. In free play mode I can't get the game to change? It only starts as soon as I press the left thumb button.
Couple things to check -
1. Do both thumb buttons work in gameplay? If not, you need to fix that.
2. Did you try shorting out the 2 pin header that is labeled "switch" on the main daughter card of the kit? That will always swap games...use this as a test to check if it's working proper, or, some use as a solution if their control yoke isn't fully functional
