Ok, I did some reading, and I believe it would be. It is the Lumber Jaques cabinet, so it's a bit older, but they say it uses the same setup as the X-arcade, presumably the dual, without the trackball like the Tankstick has that is listed here: https://support.xgaming.com/support/solutions/articles/12000003075
The setup for the controls just has the usb plugged in and not a ps2 to the keyboard, so I believe that means it would be the tri-mode if I'm reading that correctly as it seems like those that were not tri-mode required the keyboard plugin to function. Maybe I can try plugging in the keyboard adapter as well and seeing if that does anything - never had to use that before with MAME but could see if that does anything if you'd suggest it. It's a bit hard to get to as I need to remove the back panel for the cabinet but could give it a go.
Thanks,
Bill
