Summary	05331: konamigt, rf2: Steering controls stuck either all the way to the left or right after race countdown
Description	after the race starts the steering controls are stuck either all the way to the left or all the way to the right. It is fine until you steer just a little bit, then the bug happens. I keep getting stuck in the guardrails and cannot unsteer.
Steps To Reproduce
Additional Information	service mode says the steering is at 40. it should be at 00. also I am using a DualShock 3 controller (the steering is used by my left analog stick. I get no response when I am stuck.) when I do get to unsteer, every time I switch lanes, the screen flickers a bit.

I can unsteer, but every time I release the key, I automatically steer back to the guardrail.

A simple way to see the problem: Let the race start but don't accelerate. Hold right for a few seconds and release. Now start to accelerate and you will drive into the left side of track. MAME has the steering wheel set as a paddle however I believe it should be set as a dial. Unfortunately, I can't find a video of original hardware in action but take a look at this page showing the top and bottom of the control panel. I will attach a picture of the bottom in case the site goes down. https://www.worthpoint.com/worthopedia/konami-gt-arcade-control-panel-steering-wheel
