Hi, my name is JC and I need help.
So I bought this cabinet/MAME set up quite some time ago and haven't gotten around to setting it up until now.
I KNOW ABSOLUTELY NOTHING ABOUT SETTING UP MAMES, except that I want to run the cabinet on my computer tower (overqualified pc) with emulators of games to this cabinet and monitor. It's a 4 player control panel with I THINK a betson monitor?
I have the computer running the screen at a low resolution, 640x480@40hz? or 60hz? something like that I can double check if that's really important.
Anyways I took a bunch of photos to help illustrate what I'm dealing with and what the current problem is.
MY PROBLEM is that the screen is stuck with a menu screen that I can't get off of it. At start up it's not there... then around when the window's screen appears it comes on and I can't get it off.
I opened the back of the cabinet and located a sort of control panel I'm assuming controls the monitor functions. the piece is KT-2914 part OSD, the guy who made this cabinet zip tied it which I think was the cause of the "down button" becoming stuck and the "up button" being broken completely off.
What can I do to get rid of this menu screen?
Is there anything else I need to know about setting this mame up? I basically download some emulators and run them, and configure the control pannel / buttons .....
Any advice, help, recommendations and support is extremely appreciated and I thank you for your time.
