Complete List of Spinner Turns Ratios

[Major Rock Hardy]

Does this exist somewhere?

Partial at:

Did DR change the mame code or something else come of this?  If there exists a good list, it would be good to add to the wiki (I'll volunteer to add it but I need the data).

There's some info here -

Also, I checked my Ivan Ironman Offroad wheel.  It has 60 teeth on the steering wheel 'drive' shaft, and it meshes with a 14 tooth gear on the 'driven' shaft.  The driven shaft has 36 teeth on it's encoder wheel.  So that calcs out to 154.286 teeth per revolution.

EDIT - this info for the ivan wheel is for the version with the cup shaped encoder wheel, not the flat encoder wheel.

Is your Ivan wheel the version with the cup-shaped encoder and the larger dark plastic gears, or the one with the flat encoder disc and the tiny white plastic gears?

[rockin_rick]

Cup.  Forgot that there were two versions...

please help me to keep this accurate, if any info is wrong, or you have ideas about a better format for the info, let me know here or better yet, edit the wiki directly

Hope this helps someone...

p.s. by the way, did anything come of Derrick Renaud's idea of adding auto-sensitivity to MAME?

[rockin_rick]

For the sake of completeness, the specs on a Off Road wheel with the flat encoder wheel and small gears is 96 teeth drive, 14 teeth driven, 24 teeth encoder wheel.  164.57 teeth per revolution.  The drive gear and the steering wheel are on the same shaft and the the driven gear and encoder wheel are on the same shaft.

Are you saying there are two versions of the gearing?  Interesting.  I'll add the info to the wiki.

Cool, glad to see this.  I had taken those measurements a few years ago but they were *very* unscientific since I didn't have access to any of the internals.  This is exactly the kind of thing we need for close to the original gameplay (assuming you have the original controls too).

I haven't altered anything but I think this section:

Subs
Monte Carlo
Super Sprint
Drag Race
Fire Truck    36    

...should read 'Super Bug' and not 'Super Sprint'. That is based on Super Bug being the same hardware as Monte Carlo & Fire Truck. Also, Super Sprint is mentioned in the section at the bottom as being 2x or 4x (assume 2x as Champ. Sprint & APB are apparently 2x).

Good info, I will have to compare it to my guess work. I have a feeling my Pole Position sensitivity is lower than the figure I've calculated...

Edit: I didn't take into account my mouse encoder multiplier (x4 AFAIK), so I think the figures look much closer to what I guessed
