Both spinners work on all the games I tried. īoth spinners were plug-and-play with my RPi4-based RetroPie cab. Easy to configure games to original sensitivity. Direct measurement of USB events with test program confirms 1200 steps per rotation. Pro: Spins smooth and freely, just a bit more resistance than the GRS spinner.Plug-in USB adapter and set mouse index to 2 and you are playing. Pro: Knob substantial, your tastes might not require the optional flywheel.Pro: Fits in a standard button hole (28mm) easily.Extends 6cm below control panel surface with or without optional flywheel. Con(?): Deeper than the GRS USB spinner.

Spinner plus knob plus flywheel plus shipping. So you can go no flywheel, small flywheel, or large flywheel depending on how you want the inertia to feel. Note: MAME sensitivity setting maxes out at 255. Meaning no hope of getting Arkanoid/Doh working like the original (972 steps) and why Arkanoid is sluggish. So the spinner reports 380 steps per revolution over USB. After many test runs, I come up with the number 380.

Con: After much frustration not getting the MAME sensitivity equation to work for any game and never getting to reasonably responsive in Arkanoid/Doh, I adapted some USB test code to map/count the raw PPR USB events sent from the spinner.It's harder to set MAME analog sensitivity to match the original game without that number. This spinner definitely does not have dip switches to set/adjust sensitivity. I have seen people say 1024 (perhaps that is the GRS Arcade1Up with dip switch adjustments) and customer service told me 4096 (ha, ha). Con: Pulses Per Revolution (PPR) not officially documented, at least that I could find and I looked extensively.Pro: Personal preference, I like the finger spot on the top of the spinner.At least for my setup, I need an extender. Everything included no shipping cost via Amazon Prime. Plugin and set mouse index to 2 and you are playing. Pro: Spins super smooth and freely with little effort.Only extends about 4cm below the surface of the control panel. Pro: Fits in a standard button hole (28mm) very easily.Here is what I learned trying to get the games to play like the originals Then I ordered the Ultimarc SpinTrak Rotary Control with USB adapter. I chose the GRS USB Button Hole spinner for the convenience of ordering (Amazon) and the fact USB is built-in. Buttons, sticks, and trackball work great.
