Summary	07794: All sets in namcofl.cpp: The games lock up if you enter and exit test mode.
Description	Pretty much as the title says. It's possible to reenter test mode but not ingame. Final Lap R locks with an "Option Check Error" that shows weird values for seat number, rank and lap. Speed Racer stays in test mode but you are unable to move unless you flip the test switch again.
Steps To Reproduce	Enter test mode and then exit

As far as I can tell, there is no input that matches that in the menu for finalapr inputs at least, which may be interfering. Other than that, it works fine if you make changes, shut off service switch and use F3/SHIFT+F3 to restart the machine.

My second guess may be the fact this hardware was never meant to run as a single unit. finalapr on actual hardware normally boots up with a "waiting for other racer to finish" screen if not connected to any other pcbs. Somehow, mame currently hacks this out so the games can properly enter attract. Idk what the conditions and addresses are related to this as networking on this hardware is nowhere near understood. Edit: I guess I was partially correct. The "waiting for other racers to finish" screen happens if a pcb isn't receiving any data frames (open network ring). The only known way to pass this screen is to close the network ring. In the case of owning a single pcb, the pcb has to link to itself by bridging the network out pin to one of the two network in pins. Definitely a bug on actual hardware.
