This is the chip you can upgrade your game with. Your game should display the ROM version when you open the coin door and press the enter button to enter diagnostics. Note this will only work in the judge dredd pinball. You get the L-7 cpu upgrade which Williams reccommends. I do not own this software. I am merely providing a service to people without access to a rom burner. It is your right to update the roms in your game. This is what the manufacturer wanted to reduce bugs in their products. The chip is easy to install. Buy more than one item and save on shipping.

I can provide updated eproms for ANY Pinball Machine! Update them all now, and save.
