Thx I tested the code, and it's working(both in MAME and vivanonno) but either the emulation is not correct or the manual is wrong. Only the controls are reversed, I mean you steer left and the car goes right and vice versa, but the track remain intact, the curves are not reversed. Only the tachometer needle is moved to the left side of the screen which maybe indicates that is an emulation problem?. Not sure. It needs testing on real hardware to be sure. Good luck finding one
