詳 細The steering in the Atari arcade games "Hard Drivin" and "Race Drivin" in MAME behaves odd. Once the car started to drift for a while and left the road, it often keeps spinning (even on the grass) like a carousel and becomes very hard to control for the rest of the game like driving on ice. This can only be stopped by braking the car to complete halt (0 mph). I am not entirely sure if this is a MAME or game bug, or if this was even intentional game design, simulating excessive tyre wear or other car damage affecting steering - possibly exaggerated as a penalty for bad players. But arcade videos on Youtube show that on the real machine the car seems to be still controllable.

(I control it by mouse on a slightly underpowered laptop with 1.6GHz Core2Duo and Intel graphics. The game plays well but often at about 90% speed. Setting steering wheel sensitivity "6" works best.)

Strange is that seems to happen mainly in the cockpit versions. The upright versions AFAIK don't skid forever on grass, so this seems to be a MAME bug. I suspect that the car physics DSP somehow gets out of sync with the game engine or isn't resetted properly. It feels like when it acts like a state machine that by driving faults (strong steering at too high velocity/offroad) switches into a "strong skidding" mode which is intended to be switched back to regular driving mode when the car slows down enough (possibly by resetting that chip with a special signal??) but fails. Please fix this.
再現手順Try to drive too fast until the car drifts and leaves the road in a curve. The car will keep skidding like mad on grass (also when driving back onto road) untill you brake it fully down to 0 mph.
