It was in the November 1991 issue of EGM. It had an orange cover on it with the MK2 characters on it. In the tricks section it has a section for most wanted trick. There were two that month. One was that someone had taken a very horrible picture of Scorpion vs. Scorpion on an arcade machine and darkened one of the Scorpions up and called him Ermac and said he was kicked off the machine before anything happened. The other trick was that you could get the blood and the fatalities in the SNES version, but they'd be green. Also a fake.
This is the same magazine that said that you could fight Elvis and the Keebler elves in MKII and called a typo on their front cover their "April Fool's" joke one particularly lame year.
