Help hacking a Roadblasters CP
wp34:
I picked up a RoadBlasters CP off eBay. It is one of my "grails" and I've not been able to find a satisfactory way to play it in MAME. I also purchased an Opti-Wiz from GGG so I can connect it to my PC. I'm looking for some advice for hooking this up from someone who has done it and/or is smarter than me.
Here are my assumptions -
Buttons -
Large Green Wire - Ground for buttons
Large Black Wires - Trigger and Special Weapons buttons
Optical Hook-up
Red = 5v power
Black = Ground
Blue=?
Purple=?
I'm assuming that the Blue or Purple are for the X-axis.
Any guidance or suggestions would be appreciated. I've searched and not been able to find any specific information.

I found this by accident -
http://www.thisoldgame.com/products/usb-adaptor-for-atari-yoke-controller
Anybody have experience with this adapter?
bkenobi:
That yoke adapter cable is not what you want. That is for a Star Wars controller (maybe others too). What you have is a standard Atari steering wheel board. I don't remember which is which, but there's power, ground and a signal wire. There should be a writeup here about hacking a pole position or some other Atari steering wheel.
huygens:
The blue and purple wires from the optic board are the quadrature signals. They should be hooked up to Xa and Xb on the opti-wiz (you need both connected). If the mouse moves in the wrong direction just reverse them.

I thought the same thing but the item description specifically mentions RB and the molex connector looks about the same. Not sure I'd want to risk $60 on it unless someone could tell me for sure it worked. Thanks for the reply.
