Veteran Gamer. 1st-time MAME'r (Pole Position). Help me out pls.
(1/5) > >>

After some time of frustration, tohret's fits, and lack of budget, I've decided to convert my non-working Monaco GP cockpit into a MAME game for Pole Position.  I have been reading up on putting a mouse wheel PCB on the steering wheel to allow MAME to see it, but since this is all new to me I'm running into some speed bumps and could use some help.

1. the orig Monaco GP steering wheel: it's a 360 wheel so that I think is a good thing from what I've read.  What is a pain though is that the encoder wheel on it looks different from other encoder wheels I've seen: the part that runs through the original encoder looks more like TEETH on a gear, than punched out square holes that I see on other encoder wheels.  Also, the gaps between the teeth are much larger than the gaps in a standard mouse encoder wheel.  Am I going down a dark path trying to mate this original wheel encoder with a PS2 mouse opto?

2. I've read multiple things regarding how to wire up the gas pedal to use a switch rather than its current equipment, but I'm getting confused as to where you would wire this to.  Does the wiring for the switch go to the same mouse PCB that I'm trying to use for the steering?  And then when it comes to the shifter, again where does that get wired to?

3. I've read up on the opti-wiz and some other U-HID thing- I was trying to do this using stuff I had lying around at home, and I have extra mice and also a joystick that I have to see what kind it is.  Am I just making it harder on myself using these other peripherals than buying the parts that are out on the market today?  


I'll try to get some pics of all that I am looking at but wanted to hear the take from all of the MAMErs on this.  I've also viewed the classicplastic site where the guy Dave built his PP with MAME internals.  I really wish I could just get this guy to come to my house.  He'd probably have my last tasks done in an hour!

Thanks,

VG

I forgot to mention that I've got everything up and running PC-wise with keyboard, monitor, and PC, so I'm good to go there. 

It's just getting the shifter, wheel, and pedal set up.  I have also read about having to work out some kink regarding the shifter configuration using MAME, but I'll cross that bridge when I get to it LOL

Lotta good info covered in this thread:
http://forum.arcadecontrols.com/index.php?topic=108316.0

Also check out the driving cab thread in my sig.
There is a link to a spreadsheet there that will identify all the games that might be playable on the cab.
Why limit yourself to Pole Position?  :)

1. don't know anything about the GP wheel.  :-\
2. Make your pedal analogue, especially if you plan to play pole position.  (see thread above)
    The shifter can be wired to the mouse or anything else.
3. Is it the old joystick port kind?  If so, you can swap out the potentiometer in the pedal for a 100k one and wire it to the joystick.  
    How many buttons does it have?  If 4, you could wire coin, start, shift & exit to it.  If only two, you could wire the other two to the hacked mouse.
    Interfaces such as the A-PAC & Opti-Pac would make it a lot easier (and you wouldn't have to swap the pedal pot).
    Depends on how much the saved time/hassle is worth to you versus hacking what you have.

Thanks for the info, BM-

1. "Why limit yourself to PP?"   - Mainly because I want the setup to work 100% or as close to 100% as possible, and I know once I go down the path of loading multiple games, either something's not going to work right, or I'm not going to be happy with how it's working and will want to make further fixes-changes-enhancements-etc.  If I stick with PP, then all of that other pain stays away LOL
2. "Is it the old joystick port kind?"  I think so but I have to get it out from its storage cave tonight and check.

As for the pot on the gas pedal, this game actually ran an opto on it for the gas pedal.  So, I wouldn't have to switch out any pot, but I would have to install a switch that would be depressed somehow.

I will definitely check out the link you have provided to see if it's something I've already looked at before or not.  Appreciate the help!

So the Pole Position project dies at the end?  Damm that's a sad story!   :(
