I've never seen the place to enter a UKK in MKT for the PSX or N64. I think UKK are only in MK3 and UMK3 (arcade and a few other ports).

whats the UKK

if ur referring to the ultimate kombat kode then yes there is one. im not sure about for 64 but there is one for ps. u can find it on a lot of ur game code web sites. if im not mistaken u have to hold so many buttons on a certain part of the screen. it brings up a green quesion mark.

There is one for the 64 as well, it's different though. I rented it once and entered this code, it does work, from ign.com
"During the story screen, press the following buttons very quickly: HK, LK, RN, LP, HP, HP, HP, LP, LP. If it is done right you'll hear "OH-MAW" and you'll get BOTH the Red and Blue ?'s."

You can unlock smoke and khameleon (the female one) on the select screen and do i button combos, which is really cheap. There's loads of other stuff too.

I'm a greenhorn in MK.
What is UKK???
:-/

I believe it's Ultimate Kombat Kode (a superior "kode" to unlock lots of extras in the game)

i think i did it once on n64 a few years ago.i was fighting at the pit then i uppercutted my opponet down the pit then i held all the buttons it made that explosion sound,and the camera went back to the top of the pit but i think its a glitch

Guys, he's talking about the combination you have to enter on the screen you get on a GAME OVER...it says "Please enter the ultimate kombat kode" and you have 10 seconds to do it. As far as i know, for the n64, the actual code has NEVER been found, and NO SITE, not even ign, has it.

In MKT for N64, if you spin the control stick around a couple of times, you get the UKK screen. I think this is what he's referring to.
