Mortal Kombat II is the second incarnation of everyone's favorite slasher/soap opera. More characters! More gore! More -alities!

EJB Menu

The EJB Menu is an alternate test menu that can be accessed through this button code in attract mode:
1P Block (×5), 2P Block (×10), 1P Block (×2), 2P Block (×8), 1P Block (×2)

The timing on this code is extremely tight, and it's almost impossible to actually put in on time. Put the following MAME code in mk2.xml to simplify the code to 2P Block, 1P Block (×2):

  <cheat desc="Simplified EJB Code">
    <script state="run">
      <action>maincpu.mw@00439F4=D5A0</action>
    </script>
  </cheat>

You're never going to see this in an actual arcade

  • Diagnostics Tests: Identical to normal test menu.
  • Coin Bookkeeping: Identical to normal test menu.

MK2ExtraAudits.png

  • Game Audits: Acts like the normal test menu, but with five extra audits on the first page:
Sec Chip Failure
Error Traps
System Lockups
Illegal Opcodes
Clue Counter (Related to the hidden character fights)
  • Volume Adjust: Identical to normal test menu.

MK2Hello.png

  • Hello: Displays this screen of shout-outs for ten seconds, then exits the EJB menu.
  • Enter Initials: Jumps to the high score initials screen. The number of wins seems to be random, but it increases every time.

MK2EndingsMenu.png

  • Character Endings: Jumps to a new sub-menu. This displays the selected character's ending and the game credits.

Unused Sprites

MK2WWF.png

A WWF logo found inside the game. Possibly meant for an advertisement that was scrapped.

MK2 Smiley.gif

Smiley faces of unknown use. The first one is displayed in the PlayStation version whenever the game loads.

MK2DeadPoolSky.png

A red sky background meant to be seen inside the grates on the wall of the Dead Pool background like in the Super Nintendo version and on the Nintendo 64 version of Mortal Kombat Trilogy. In the normal version the background is merely dark green.

MK2AcidBubbles.gif

Acid bubbles meant for the Dead Pool background.

MK2AcidBubbles2.gif

Acid splash meant for the Dead Pool background.

MK2 PortalGreenTemple.png

This can be seen in the Portal background by using a MAME cheat to break the screen limitations (so you can walk off the edge). It was later used in Mortal Kombat Trilogy.

MK2MoonSilhouettes.png

Silhouettes from the Pit background found in the original Mortal Kombat.

MK2KintaroIntro.png

Silhouette which seems to be Kintaro. May have been meant for an intro screen like Goro's intro screen in the original Mortal Kombat.

MK2 NinjaFloorProjectile.gif

One of the male ninja characters throwing something on the ground.

MK2BarakaSparkle.gif

Baraka's blades were probably meant to sparkle during his win pose.

MK2BarakaFlip.gif

Looks like Baraka was meant to have some sort of flip move with his blades extended.

MK2BarakaSpin.gif

This move was later used in Mortal Kombat Trilogy.

MK2 KintaroStand.gif

Kintaro standing. The shading implies it was meant for Kahn's Arena.

MK2 KintaroGrabAttack.gif

Kintaro grabbing and hitting opponent. This move was later incorporated into Mortal Kombat Trilogy.

MK2KungLaoHatShine.gif

Shine meant for Kung Lao's hat during his winning pose.

MK2KungLaoHeadbutt.gif

Had this been used in game it would have made Kung Lao's headbutt move less confusing. It shows he is actually attacking by using his hat.

MK2KungLaoTorpedo.gif

This was used for MK2 Kung Lao in Mortal Kombat Trilogy for the PlayStation, PC, and Sega Saturn.

MK2RaidenWinLightning.gif

Lightning meant to go around Raiden during battle like in Mortal Kombat. The design is the same as that game but redrawn to match the style of the lightning of this game.

MK2 RaidenShocker.png

Raiden lifting up and shocking someone. Likely a Fatality. Raiden would eventually use a similar Fatality in Mortal Kombat 4.

MK2ShaoKahnStanding.gif

Shao Kahn standing up. Shao Kahn was probably supposed to stand up after you beat Kintaro since he is seen sitting in the background of the level.

MK2 ShaoKahn HandClap.png

Shao Kahn doing a clap. Perhaps shot out a projectile.

MK2 ShaoKahnGlow.png

Shao Kahn glowing. Unknown use.

MK2 ShaoKahnGrabAttack.png

Shao Kahn grabbing the opponent and hitting him. He would acquire this move in Mortal Kombat Trilogy.

MK2 ShaoKahnHandSmashFatality.png

Looks like Shao Kahn was originally meant to have a Fatality. These sprites show him punching the ground and a large hand which probably smashed the opponent.

MK2 ShaoKahnHeadSmash.png

Shao Kahn hitting opponent with both hands simultaneously. This was later used in Mortal Kombat Trilogy.

MK2 ShaoKahnSledgehammer.png

Shao Kahn using a sledgehammer. These sprites would later be inserted, yet unused, in Mortal Kombat 3.

MK2 SubZeroAirFreeze.gif

Looks like Sub-Zero originally had the ability to do a freeze blast while in mid-air.

MK2 Staff.gif

Sprites of various staff members. Perhaps they were meant to be shown on the Pit II bridge during the credits, like the motion capture actors were?

Unused Sounds

Hmmm...
To do:
Are any of the sounds in here actually unused?

There are several unused sounds in this game, mostly carry overs from the first game. There are, however, several vocal tracks and sounds for both existing and unknown characters.

General

Male Vocal: Yeah!
Unknown purpose. Possible win pose vocal for an unknown character or something else entirely.
Male Vocal: Yeaaaaaaaah!
Unknown purpose. Possible win pose vocal track for an unknown character or something else entirely. It was most likely a placeholder track for Kintaro's roar as it sounded like Goro from the previous game.
Female Sound: Kiss
Most likely an alternative to Kitana's normal kissing sound.
Male Sound: Kiss
Seems to align perfectly with Johnny Cage's win pose, but for some reason goes unused.
Female Vocal: Inflate Strain
Female characters use the male strain vocal track when Kitana's kiss is performed on them. It is unknown why this was left unused.
Male Vocal: Muffled Laugh
The laughing portion of this track was later used in the home console ports of Mortal Kombat 4.
Male Vocal: Attack 1
An attack vocal track for an unknown male character.
Male Vocal: Attack 2
An attack vocal track for an unknown male character.
Male Vocal: Attack 3
An attack vocal track for an unknown male character.
Male Vocal: Attack 4
An attack vocal track for an unknown male character.
Male Vocal: Damaged
A vocal track of an unknown male character receiving damage.

Developer Tools

Display Hitboxes

Setting ram address 1061FB0 to a non-zero value will enable a hidden development tool that was most likely used to help the developers position hitboxes correctly with their corresponding moves. This tool is also hidden within the 32-bit home console ports of the game, where it has been expanded to display damage areas (marked in red) on the opponent in addition to the attack related hitboxes (marked in green).

Audits

I've never seen a Kano transformation...

In the test menu there is an audit screen that lists several statistics that the game keeps track of. Some of these don't actually do anything and never go up, being there simply to stir up rumors and hype among the game's fanbase, something seen in other Mortal Kombat games.

  • Shawn Attacks: Who knows? Doesn't seem to be any Shawns listed in the credits.
  • Kano Transformations: Kano is present in the game, but solely as a background element. (It really stands for SEC Chip Failure*).
  • Hidden Audit*: Located at 0x1400A40 in NVRAM. Tracks the amount of times Shao Kahn has has been defeated. This is not displayed in the audits.

Win Text

The following win text is located on ROM chips ug12/uj12 (interleaved) starting at 0x04832. They were most likely put in as a joke. This is the first mention of a character named Tanya, who was eventually seen in Mortal Kombat 4.

KANO WINS
SONYA WINS
TANYA WINS
ERMAC WINS
ED BOON WINS
JOHN TOBIAS WINS
MARK TURMELL WINS
SAL DIVITA WINS

Unused Audits

There are two unused audits in the game. Audit text starts at 0x491FC:

   S TAKEN
DOOR SLAMS

" S TAKEN" is probably a coin counter, while "DOOR SLAMS" would count the number of cabinet tilts. Similar audits appear in games that use the Midway Y Unit system.

Unused Stage Name Tag

You have reached the outer limits of the tournament. Now you both must face a level from your past.

Usually you can only fight in the hidden Goro's Lair stage when fighting against the hidden characters, Jade, Smoke and Noob Saibot. If one uses hacking or cheats to choose the stage in a 2 player game, it will show up on the VS screen as "No Name."

Oddities

Advertisement is for lesser mortals!

Johnny Cage was filmed wearing Otomix brand athletic pants with a very visible logo. Most of the sprites had this edited out, but when doing Shang Tsung's soul steal fatality, it can still be seen briefly before his corpse withers away. Obviously they just forgot to edit this out, as the sprite is only seen in that one specific fatality.
