Arcade Spinner Games and MAME Sensitivity Settings
DarthMarino:
I should mention that you need to play Konami GT on a recent version of MAME. The dial inputs were fixed in the March release.

OK, I think I've figured out our communication disconnect. :cheers:
Atari games like Warlords originally used pots with a slip clutch.
- If you turn the pot in one direction, the wiper will stop turning when it reaches the 5v or ground terminal, but the slip clutch will allow the shaft to continue to turn so the pot isn't damaged by over-torquing. You can hear the wiper hit the terminal stop at 1:50 in the video.
- With this setup, the wiper will not directly jump the gap between the 5v terminal and the ground terminal.
- The terminal stops allow less than 360 degrees of wiper rotation. (not free spinning)
A free spinning pot is like the one in Omega Race.
- If you turn the pot in one direction, the wiper will not stop turning when it reaches the 5v or ground terminal.
- The gap between the 5v and ground terminals is large enough that the wiper won't short them together.
- With this setup, the wiper will directly jump the gap between the 5v terminal and the ground terminal.
- Having no terminal stops allows an unlimited amount of wiper rotation. (free spinning)

It seemed to play fine with my analog joysticks last I checked. *Edit* It was fixed in MAME: "0.222: Fixed Road Blasters steering wheel does not auto center. The RoadBlasters steering wheel is very much like the Star Wars yoke, without the vertical (Y) axis [Curseur, Tafoid]. Replaced Dial controller with Stick."

Thanks for the info. Sounds like that update should make it work much better with potentiometer controllers. ;D

Thanks for the info, Scott. :cheers:
Aqua Jack is another game that is incorrectly listed as dial control in MAME, when you can clearly see the 5k pot joystick on page 17 in the game manual. http://www.aurcade.com/games/manuals/00002239.pdf

I'm trying to configure my spinner using this guide. What menu am I supposed to be changing the dial settings?
If I go to "Input (this Machine)" there aren't any dial sensitivity settings to change. Should I be going into "Analog Controls" and changing "Dial Sensitivity" there? Does this save to the cfg file of the currently selected game or is this a global (all of MAME) change? Obviously, I would want different settings for different games...
Also, as an aside - I had a hard time just getting the spinner to work in MAME because the SpinTrak plugged into the iPAC2 is recognized as Dial 2 and not Dial 1. Or do I have something screwed up? This is how I have it connected.
Thanks!
KenToad:
Yep, change the sensitivity in analog controls and it will be saved in the game specific cfg file.
Your connection looks correct to me, but I can't verify, as I use Turbotwist 2's with their propietary connection.
It doesn't matter to MAME which mouse number it is. My Turbotwists get recognized as mouse 2 x and y. You just spin the spinner when you're mapping dial controls as whatever dial number x or y axis. It's easiest to map dial controls in the general controls.
