Purpose
This is intended to be a page to keep track of the correct turns ratio of spinner/dial/paddle/trackball-controlled arcade games. Below is comma-separated text, hopefully this is a useful format.
Q: How do I use this information?
A: To tweak the analog sensitivity in MAME to better emulate real hardware.
An example from the first link below:
Tempest, 72 count
if the control you use has 1200 counts per turn, the sensitivity calculation is: Sensitivity = 100 * 72 / 1200 = 6%

Data
Effective_Tooth_Count = teeth that pass through the optical sensor per revolution of the knob (multiply by any gear ratios to obtain)
Counts_Per_Revolution = could be 1x, 2x, or 4x of the Effective_Tooth_Count (depends on original hardware interpretation of optical sensor information)
Other_Notes = quantitative information relating to game play (like degrees of turn from one side of the screen to another - useful for potentiometer games like Warlords)
| Game | Effective_Tooth_Count | Counts_Per_Revolution | Other_Notes |
|---|---|---|---|
| 720 degrees | 72 | 144 | LETA 2x (schematic) |
| Arkanoid | 486 | 486 | Geared: The knob attaches to shaft #1, which has a 72 tooth gear on it. That gear turns a 16 tooth gear on shaft #2. Shaft #2 also has a 72 tooth gear on it, which then turns a 16 tooth gear on shaft #3. Shaft #3 also has the encoder wheel on it, which has 24 teeth. 120-130 deg = one traversal across the screen |
| Aztarac | 4x | Same spinner as Mad Planets | |
| Blasteroids | 72 | 288 | LETA 4x (schematic) |
| Crater Raider | 64 | 64 | |
| Caliber .50 | 24 | Loop24 optical rotary stick | |
| Cameltry | 486 | Same Spinner as Arkanoid | |
| Dark Planet | 64 | 64 | 6-bit rotary encoder |

| Disks of Tron | 128 | 128 | |
| Forgotten Worlds | geared spinner | ||
| Ivan Ironman Offroad | a) 154.286 or b) 164.57 |
Geared: a) 60 teeth on the steering wheel shaft, meshes with a 14 tooth gear on the encoder shaft, which has 36 teeth on its encoder wheel b) 96 teeth on steering wheel shaft, to 14 tooth gear on encoder shaft, which has 24 teeth on encoder wheel. | |
| Kick / Kickman | 12 | Ball-shaped roller. | |
| Off the Wall | 128 | 256 | LETA 2x (schematic) |
| Omega Race | 64 | 64 | Omega Race uses a 6-bit (64-position) rotary encoder |
| Pole Position Pole Position II |
102 6/7 | 102 6/7 | Geared: 60 tooth gear on wheel shaft, 14 tooth gear on 24 tooth encoder disk shaft => (60 / 14) * 24 = 102 6/7 |
| Revenge of DOH | 486 | 972 | Same spinner as Arkanoid |
| RoadBlasters | 154 2/7 | Wheel/Yoke: 60 tooth gear turns 14 tooth gear with 36 tooth encoder disc. Limited angle of rotation. | |
| Super Speed Race | 64 | 64 | 6-bit rotary encoder |
| Tempest | 72 | 72 | 1 full turn moves 5 spaces on first screen |
| Tron | 128 | 128 | |
| Two Tigers (conversion) | 64 | 64 | |

| Happ 2.25 inch trackball | 149.2 (no wear) | 2.25 inch ball, 0.362 inch roller, 24 tooth encoder disc |
| Happ 3 inch trackball | 167.4 (no wear) | 3 inch ball, 0.43 inch roller, 24 tooth encoder disc |
| Atari 4.5 inch trackball | 330.6 (no wear) | 4.5 inch ball, 0.49 inch roller, 36 tooth encoder wheel |
Trackball Games

Pot Based
| Game | Gear Ratio | Other_Notes |
|---|---|---|
| Warlords | 1 | 120-130 deg one traversal end to end of castle |
| Final Lap | 2/3 | |
| Moto Frenzy | 1 | |
| Breakout | 1 | |

Trackball Games: Game Name, Notes
Crystal Castles, 1st screen BB moves length of line above his head from center of trackball moved to one side
Centipede, 1 trackball move 1 end to other (stock tb) 2 1/2 mushroom lengths
Missile Command 1 full end to end visible trackball movement goes from left to the right of the little bump after the missile base
Atari LETA Chip:
several of Atari's optical-control games used the LETA quadrature-decoder chip. It could be set to a 2x or 4x resolution. Therefore all of the below games are either 2x or 4x.
Major Havoc
Marble Madness
Crystal Castles
Rampart
Off The Wall
Blasteroids
720
Championship Sprint
Super Sprint
APB
