Nintendo Punch-Out to JAMMA Adapter

Description

Allows you to play you Nintendo Punch-Out!! in a JAMMA cabinet or a supergun device.

Punch-Out is an arcade boxing video game deleloped and released by Nintendo in 1984. While production numbers weren’t as high as other Nintendo games of that period likely due to higher purchase price, it didn’t stop Punch-Out from becoming an instant success and earning it the title of the best performing arcade game of 1984 in the United States.

Punch-Out arcade cabinets have two dedicated monitors, one for gameplay and another one for stats, round time and player and opponent health. In order to display this information the adapter has an on board video switching circuit that can be switched to the stats screen via a press of a button. The adapter also contains a video inverter circuit and and an audio amplifier to ensure full JAMMA compatibility.

Nintendo eventually produced a sequel known as Super Punch-Out, and a spin-off game called Arm Wrestling. The adapter is compatible with both of these games as well.

The adapter has been tested with genuine Nintendo Punch-Out and Super Punch-Out boards.

Important: Each monitor is driven by an independent timing circuit on the Punchout PCB. The timing between the two video signals may be out of sync to such an extent that it may require an adjustment to the V.HOLD and H.HOLD adjustment on the monitor to sync properly when switching from the game screen to the round info / timer screen.
