I Have a 2 working rush 2049 cabinet. I would like to build a mame/model2 cabinet but i would like to preserve the game.
So basicly my goal is to interface the original controls to a pc and be able to switch back to the original game (rush 2049) if i want to play the game.
That's where the JAMMA fingerboard (male) comes in. (might need some Molex adapters, too
)
Page 84 of the manual (linked above) shows the cab's JAMMA harness edge connector (female) connected to the Game PCB edge connector. (red)
What you need to research/build is everything connected through the fingerboard. (green)
To switch from the Game PCB to the computer, power down, disconnect the JAMMA edge connector from the Game PCB edge connector (red) and connect to the fingerboard. (green)
Game PCB

RGB video from the computer connects through the fingerboard and JAMMA harness to the monitor.
The computer has an analog encoder plugged into a USB port and connected to the buttons and potentiometers through the fingerboard.
If you want to run all the analog controls (wheel+3 pedals*two players=8 analog axes) through one analog encoder, you may want to consider "rolling your own" KADE maxArcade. (See the AVR vendor list in my sig for details regarding the
board and a
pinout.)
It's a cancelled prototype (none for sale), but the "KADE maxArcade - USB/HID Joystick 2 Player with Analog (Beta)" firmware works and can handle 8 analog axes.
I'm not familiar with all the details of your cab (just working from the manual), but this is the basic idea of what you need to research to build what you described.
Good luck.
