I found an MK1 Arcade manual from July 1992. Too bad this forum won't let me upload images. Reading through it I notice the dip switch diagram shows unused dip switches. The audits table of contents spells Kano's name wrong: "Kans". There is no mention of # of Reptile appearances, # Reptile Battles, Goro or Shang Tsung. What it does have is a counter for "Error Traps".
