Summary	01848: speedrcr: i960 CPU crash
Description	During attract mode mame exits with this error message: i960: 128382c8: Unhandled 18
Steps To Reproduce	Let the attract mode run.
Additional Information	It's difficult to get the game to actually start, I think there's something wrong with the calibration in test mode. You have to calibrate the wheel and gas pedal to get the game to start. I can only get it to register "right" on the x-axis no matter if I use mouse, keys or joystick. NVRAM with calibration done attached.

It seems in either case the emulation dies out pretty good. There is a bug (01701) related to calibration issues as well. It would be useful if someone could find a regression (my computer is rather slow - so regression finding would be tedious for me).

Also the road graphics are broken in a new and interesting way. See screenshots. I'm not sure if I should file a new report or if it's OK to keep the new bugs here?
No.03891 Canim Senior Tester Mar 6, 2009, 03:43	Can someone still confirm this crash. The calibration and the steering are alright. I let the intro run 3 times nothing of a crash or freeze to see. Except the road seems not to be where the cars are but that's a video emulation bug that shouldn't be reported. Maybe this can also be closed.

Another thing about the inputs - the TAB menu lists a second analog pedal but there's no evidence that one exists in Speed Racer's calibration sequence or in the test menu? (btw I think it was my mistake not being able to calibrate when i filed this report. I didn't know that you could select the either a full analog axis or just - and +). Otherwise, car sprites are back and the game seems fully playable but a lot of graphics are missing. I'm going to use my senior tester powers and close this, hope it's the right thing to do.
