Summary	08831: contcirc: Contcirc does not work correctly with a 360 wheel. Can only be detected on high score select screen
Description	I have an original Continental Circus Arcade cabinet that I'm using with a Mame PC. The steering wheel is recognized as a mouse using an Arduino Micro Pro. The controls in contcirc seem to be working fine but the problem becomes apparent when getting to the high score select screen: The letters in the high score select screen spin by without stopping. Through steering left or right I can control in which direction they are spinning and sometimes if I spin in the same direction as the letters progressing, I can get it to stop for a second. The game plays fine otherwise. Pole Position which also has a 360 wheel works without problems in high score select screen. By moving the wheel left and right I can select the correct letter. Both games are quite similar in peripheral hardware to my knowledge. Here is a video showing the problem: What I tried unsuccessfully: - Steering free or locked in Dip settings, - Auto centering to 0 (only available in locked mode) - Various Sensitivity adjustments Since Pole Position is working as it should, i suspect a bug in the input system for contcirc
Steps To Reproduce	Use an analog 360 steering wheel (or other free spinning analog input device like an Arcade spinner) and play until high score screen. I created a save state of the high score screen in contcirc here: https://drive.google.com/file/d/1yO8p2w-284tuN5RSHuSzNoqvu-7yKz-z/view?usp=sharing (Unpack into mame/sta/contcirc folder and hit f7 to load while in game).

No.22016 mrchrisster Tester Mar 19, 2024, 19:21	Just confirmed that chasehq displays correct behavior when setting steering mode to "free". When reaching the Highscore screen advancing one letter at the time by turning the steering wheel. I tried some more ways in contcirc but letters continue to spin in free mode.
