I didn't know the fergality existed in the DOS version of MK II. I thought that was an exclusive Genesis ality. And I apologize because I can't answer your question.

I'm pretty sure it was only in the Genesis Version. I never heard of it existing on any other.

there is no fergality in DOS version.

if you open MKTRILW.EXE (MK Trilogy WIN) file with HEX Editor there are lines like: "Hyper Fatality" "Boon Wins" "Tobias Wins" etc there is a text even for Galaga but they are not in the entire game.

And, as a side not, if you open MK2 Demo for DOS in an editor you can find, burried in the middle of the file the phrase, "You have no life." I guess commenting on the idea of someone looking through an EXE file to find secrets...which I did. Oh well.

yeah, i wanted to change some characters bios and find this stuff lol
