Compatible Games

This is the list of compatible games that can be used with this adapter:

The adapter has been tested with genuine Capcom boards and several bootlegs for compatibility.

Revision History:

Rev 1.3: Resized the board for consistency. This is the currently available version.

Rev 1.2: Changed silkscreen to be more readable. Removed grounds for coin counters. This seems to short out some bootleg games.

Rev 2.0: Added button mapping jumpers for cabinets with alternate wiring. This isn’t techinically necessary since Gunsmoke correctly maps left, middle and right buttons to button1, button2, and button3. This version has been discontinued, and version 1.2 is the current production version.

Rev 1.1: Added additional grounds.

Rev 1.0: Initial version. Obsolete now.
