Mortal Kombat II (Arcade)
|Mortal Kombat II|
This game has a hidden developer message.
Mortal Kombat II is the second incarnation of everyone's favorite slasher/soap opera. More characters! More gore! More -alities!
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, 1P Block:
<cheat desc="Simplified EJB Code"> <script state="run"> <action>maincpu.mw@00439F4=D5A0</action> </script> </cheat>
- Diagnostics Tests - Identical to normal test menu.
- Coin Bookkeeping - Identical to normal test menu.
- 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.
- 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.
- Character Endings - Jumps to a new sub-menu. This displays the selected character's ending and the game credits.
A World Wrestling Federation logo found inside the game. Possibly meant for an advertisement that was scrapped. Midway would develop WWF WrestleMania: The Arcade Game two years later.
Smiley faces of unknown use. The first one is displayed in the PlayStation version whenever the game loads.
A red sky background meant to be seen inside the grates on the wall of the Dead Pool background like in the SNES port of this game and the Nintendo 64 version of Mortal Kombat Trilogy. In the normal version, the background is merely dark green.
Acid bubbles meant for the Dead Pool background.
Acid splash meant for the Dead Pool background.
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.
Silhouettes from the Pit background in Mortal Kombat.
Kintaro, assumed to once be in the intro of MK2. The face portion of this image would later be used for Kintaro's character select portrait in Mortal Kombat Trilogy.
Silhouette which seems to be Kintaro. May have been meant for an intro screen like Goro's intro screen in the original Mortal Kombat.
One of the male ninja characters throwing something on the ground.
Baraka's blades were probably meant to sparkle during his win pose.
Looks like Baraka was meant to have some sort of flip move with his blades extended.
A spin move for Baraka, later used in Mortal Kombat Trilogy.
Kintaro standing. The shading implies it was meant for Kahn's Arena.
Kintaro grabbing and hitting an opponent. This move was later incorporated into Mortal Kombat Trilogy.
Shine meant for Kung Lao's hat during his win pose.
Had this been used in-game, it would have made Kung Lao's headbutt move less confusing, as it shows that he's actually attacking by using his hat.
This was used for MK2 Kung Lao in Mortal Kombat Trilogy for the PlayStation, PC, and Sega Saturn.
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.
Raiden lifting up and shocking someone, likely a Fatality. Raiden would eventually use a similar Fatality in Mortal Kombat 4.
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.
Shao Kahn doing a clap. Perhaps he shot out a projectile or created a shockwave.
Shao Kahn glowing. May have been used as a shield when he is laughing, but it is more likely that this was intended to be used during the final defeat sequence where he teleports through all stages, since he uses that pose there.
Shao Kahn grabbing the opponent and hitting him. He would acquire this move in Mortal Kombat Trilogy.
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.
Shao Kahn hitting the opponent with both hands simultaneously. This was later used in Mortal Kombat Trilogy.
Shao Kahn using a sledgehammer. These sprites would later be inserted, yet unused, in Mortal Kombat 3.
Looks like Sub-Zero originally had the ability to do a freeze blast while in mid-air.
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?
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.
|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 Jax or something else entirely. Could also be a placeholder unfiltered 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.|
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, 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).
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. (This is actually just a different name for the "Sec Chip Failures" audit.)
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 eventually made her debut in Mortal Kombat 4.
KANO WINS SONYA WINS TANYA WINS ERMAC WINS ED BOON WINS JOHN TOBIAS WINS MARK TURMELL WINS SAL DIVITA WINS
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
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 two-player game, it will show up on the VS screen as "No Name".
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 be seen briefly before his corpse withers away. Likely a simple oversight, as the sprite is only ever used in that one specific Fatality.
There is an audit located at 0x1400A40 in NVRAM which tracks the amount of times Shao Kahn has been defeated. Strangely, this is not used on the standard Game Audits screen, even though Mortal Kombat had a similar one for Shang Tsung.
