Summary 02776: mwalk, mwalkj, mwalku: Crash when starting game
Description Immediately after pressing 1P start, the game crashes and the following error is displayed:

CPU mcu: PULSE_LINE can only be used for NMI and RESET lines

I am not sure if this is related or possibly a second issue, but the game also does not fully stretch the video. I have confirmed the settings are identical between Moonwalker and the other segas18.c games, which work properly. Normally MAME stretches the display to the height of the screen and maintains the aspect ratio. With Moonwalker, the display is stretched, but does not fill the full height of the screen. It would appear the stretch is roughly 2x normal, resulting in the game displaying in a box in the middle of the screen that is approximately half the size of a normal game. Again, all settings have been double-checked and confirmed to match those of the other games sharing the driver.
Steps To Reproduce Enter coin, press 1P start.

I can confirm the crash in u6 - the latest u7 release doesn't even boot properly (hangs at a black screen after OK).

You video stretching issue may have to do with an artwork file in your ARTWORK folder. Either move it out or temporarily rename it to see if this corrected that problem.

Thanks for the update on the crash. Also, removing the artwork did indeed fix the stretching issue.
