Warning: People have reported issues after getting into MK's test menus. I have done extensive testing and even tried breaking an A1U Mortal Kombat cabinet using the test menus but could not get it to fail. I still would like to warn you that there is a risk of your arcade failing by poking around in these menus. Do this at your own risk!
