It's definitely the joystick.Maybe, but maybe not.
Besides testing it on a different monitor than a 4600 to see if I can sync it, @64B1T brought up how its weird that it doesn't show the full attract mode. And that Mame also doesn't show the full attract..
The board still has one of the SEEQ eproms I want to replace and the little switchers I'm using for test powering the boards don't like how much power this boardset pulls. I may need to check how many amps it's actually pulling.
The other variable is that I don't have a joystick hooked up and may it being out of limits or whatever the message is may be making the attract screen cycle through screens.
Tested it out on my machine. If the machine thinks the joystick is not centered with reference to the calibrated value, it will shortcut attract to show the high score table as often as possible. This is probably expected behavior when you don't have a Joystick plugged in.
