Hi, First time posting.
I have a CGA/VGA Jamma 48/1 Classical Game Collection. When I power it on with all DIP switches off it should allow the game selection and playing. However, it is just frozen in the wake up screen/demo. Joystick, P1, P2, Button1,2 do nothing. I can set DIP 4 to the ON and go through the whole selection screens. Even in the IO test screen every button, direction, and DIP switches show they work. But when I turn off the set up and boot up in play mode it's stuck again.
Any suggestions?
