Mortal Kombat II (NES)
|Mortal Kombat II|
Despite the name, the NES Mortal Kombat II is actually an unlicensed port of Mortal Kombat.
"Skang-Tsung" does have a fireball attack similar to the original game, which is done by pressing Back, Forward, A. You never see it during normal play because the AI never performs it, and trying to do the command yourself will cause you to transform into another character that will perform their projectile attack.
The only way to see this is by changing the value under 00A3 to 08, which will allow you to play as him without the ability to transform.
Super Fighter III Leftovers
The lifebar and lowercase font shown here isn't used in any part of the game. It turns out these were originally from Super Fighter III. Hummer Team made a game before this called Master Fighter VI' which is probably why these appear here. (Interestingly enough, the lowercase font isn't used in Super Fighter III or Master Fighter VI' either.) This isn't the only thing that came from Master Fighter VI' however...
At 00A3, values 09, 0A, and 0B contain these fully functional but nameless Raiden clones with strange palettes that appear to have no significance. However, these three contain palette data and special move commands from E.Honda, Zangief, and Ken from Master Fighter VI'. This along with the Super Fighter III graphics may imply Mortal Kombat II was originally built off of Master Fighter VI.
A corrupted fragment of code can be seen in the ROM. Some restoration was done to remove some of the garbage text. This begins at 18B8 in the ROM, but a few pieces of this are spread throughout the ROM:

Mortal Kombat II (Rev. B)
This version of the game fixes a bug that prevented the scrolling up animation on the title screen's menu from activating. In Rev. A, the menu is static but still makes the sound for when the animation is supposed to stop.
Mortal Kombat II (Blue Logo Version)
The only difference between this and the original, other than the logo, is that the animations in all the stages appear broken.
Mortal Kombat II Turbo
A title hack of Rev. B with the only differences being that the animation on the title screen's menu is broken again (instead of scrolling up, it just vibrates in place) and that Liu Kang, Kano and Scorpion are using their second player palettes instead. Another variation of this has a blue Mortal Kombat logo instead.
Mortal Kombat III Turbo/Mortal Kombat III
Mortal Kombat III Turbo changes the menu on the title screen (but doesn't fix the vibrating menu), gives every character their own clone on the select screen and alters some of the stages. Mortal Kombat III is the same as the turbo version, but with a different title screen.
Similar to the Mortal Kombat II Turbo revisions, the palette swaps in that revision also occur here. Mortal Kombat III appears to be an unofficial hack, since JY Company never released that version. However, the expanded roster can be accessed in the original game by freezing 0x0050 in memory to 03, suggesting that Hummer Team might have released Mortal Kombat III under a different publisher.
