If you tired of your rapid fire chip and want a greater challenge, or just want to make your Galaga play like the ones in the arcade did, this chip is for you. Many arcade enthusiasts prefer the original. This chip will put your game back the way it was when you played it for the first time in the arcades. Much more challenging. This chip replaces chip 3J on original Galaga boards and restores your game to stock.

Comes with illustrated installation instructions.
