Hi folks,
I'm hoping someone here takes up the gauntlet for enhancing the xxx-to-JAMMA adapters (Pac to JAMMA, etc...) to create new, better ones.
Here are some things that can be done:
Mr Do to JAMMA: Add a jumper block to allow for tying the coin inputs (pins 24/25) high through 1K resistors. This would allow for Cosmic Avenger and other boards that run 5v to the coin switches to be used with the adapter.
Galaga to JAMMA: Add wires from 18/19 to 8/10 to connect up/down for use with Bosconian
Galaxian to JAMMA: Add a jumper block to allow for connecting 22 to 9, 18 to R and 19 to 14. This would allow for bootleg systems based off of Galaxian such as King and Balloon, Moon Cresta, Pac boolegs, and more to be used with it. The reason for the jumper block on this one is that if you press "up" on a stick when a real Galaxian board is installed, it reboots the board.
