I want to get free plays on the Killer Instinct Arcade game by Nintendo and Midway circa 1994. I do not have access to the inside. I can unplug it. I have 8 hours to play at work and no one to see. Any one who can answer this would be most appreciated. I have googled for manuals, hacks, and anything else I can think of. The instruction manual numbers are DO0035 from 1995 and 16-40047-101 from 1994. I cannot seem to find the actual manuals though. Just the numbers. I got those from http://www.andys-arcade.net/personal/manuals.htm. So here is the challenge. Find the way to get free plays without opening the machine. Now that you have your challenge lets see who can conquer it. This does involve a little bit of hacking. Have no fear. My company owns the machine. Therefore there is nothing illegal involved. I do not want to use slugs...I already know how to fish with the quarter and string. I want to use to the audit screen.
