I like the wacky ones that don't really affect the gameplay. Big head and fatty kombat would be fun.

I wouldn't mind the Kombat Kodes coming back. We only saw them in MK3[UMK3/MKT] and MK4[GOLD], and yes, if we're referencing MK3, we might as well bring these in as well. I don't see why not

Kombat Kodes were okay. I found them to be a pain, so I never did them.

Let them die.

Hell yea, big head mode!

no throws!

It'd be great to have them again, certainly.

Throws encouraged!

Imputing the Nude Kombat code results in an instant console ban lol

Bring them in.Also the MK3 SLOTS. :P

-No Specials
-No Jumps
-No Blocking
-No Throwing
-No Running
-No Diving
-No Parking Any Time
-Big Head Mode (like MK4)
-Dark Kombat (everyone looks like Noob)
-Goofy Voices (regular voices are replaced by cartoony-versions of themselves, who have different lines, often not about fighting)
-Random Kombat (IIRC this code was used to randomly change your characters during a match, this would be awesome again)
-No Backgrounds (FIGHT IN A BLACK VOID)
-Kid Mode (blood/gore is replaced with flowers candy and rainbows)
-Winner Fights "X" (used to fight against any hidden bosses/bosses in the game)
-Winner Invades The North Pole! (Beat'em Up where you have to fight legions of elves and have a boss fight with Santa Claus..when you get to Santa it is done in the regular game's engine)

Here's a good one.
Fart Kombat - The music is remix with a fart sound by Bo Rai Cho while you were playing it.

I loved doing the kombat codes. I remember putting in as many random combinations as possible without knowing what the outcome would though in retrospect I usually hated the ones that I did put in.

Now a fart kombat kodes can be very very funny, and it should add in MK9.

Here's the list of fart kombat kodes.

Fart music: The music is remixed with a fart sounds by Bo Rai Cho.
Fart Sound: The sound you hear if you select things you hear a fart sound.
Fart hit: You hear a fart sound everytime your character hits the opponent in the middle of the fight.
