Hey guys, I'll tell ya a story:
It was a beautiful day, I was playing MK1 in my Genesis emulator and looking for some tricks in GameWinners. All OK till there. Then, I saw the cheat on how to fight as Reptile. It said I had to enable the shadows passing in front on the Pit's moon and the starting stage as the Pit. Then, I had to fight him every time I was to fight on the Pit and defeat him every time with a fatality.
Then, I started to hunt down this freakin' bastard:
So, I reached out for him three times (including the one after Endurance 2), defeated him and fatalized him (note: I was playing with

Johnny Cage) every one of the three times (even that freakily glitched Sonya, that teleports like crazy when I'm about to finish XD), and beat the game. When I got back to the beginning... Whoa! Shouldn't Reptile be in the space between Kano and Sub-Zero?!
What went wrong? Did anyone unlock Reptile? If so, can you please tell me what's the correct way?
