 Williams high score patches released!

By popular request, I patched all of the 'classic' williams games to allow you to fill the entire high score list with your initials rather than being limited to 5 entries. More information and links to the romsets can be found here.

JAMMA Adapters For Sale

JAMMA adapters are made to order. $45 covers most standard 1-edge connector adapters. Adapters with more connectors or external circuitry (audio amplifer, sync combining, sync inversion, video inversion, joystick to trakball conversion) cost extra. Power is run in 16ga solid wire for support, and other signals are run in color coded 20ga wire. They end up looking something like this: [jpg][jpg]
