First off this happen to me like 5 years ago so forgive me if i dont explane everything right.You have to do like the scott stuff thing or kool or whatever code on the start,and set the timer to max fatality time.BTW this only works in two player at the start.First person pick liu and second person picks nightwolf.When it saids finish him make sure the first person is still jumping around(it happens as a glitch sometimes)now do nightwolfs friendship and he will turn into raiden.Now at this point you have to hit raiden and he will stop out of his pose and you can use him for 2 second.He has nightwolfs moves.1st person doesnt continue,otherwise it will lock up the game.When you start on the latter mode thing or whatever.It will be glitchy at first but give it time other wise the game will lock up.You cant win the game of course cause theres no ending,It will freeze up before shao kahn get defeated.It only worked for me twice cause you have to be fast when your tring to kick raiden during nightwolfs friendship.
