I couldn't check Racing Jam itself since it doesn't boot in MAME, but based on the behavior of other Konami games on the same and similar hardware it looks like the settings in the operator menu are stored in the TimeKeeper. From what I could see, as long as the TK contents are valid on boot, you could probably get away with it not being writeable, but I can't guarantee that.
Incidentally, do you happen to have documentation on what the LED codes for Racing Jam mean? MAME goes through a bunch of numbers and then stops on "50" when it dies.
