Here’s Mortal Kombat 2, which recreates the original environment of the home console version(s) of MK2 in a form of a NES hack.
Features:
original palettes for the game
MK dragon symbol instead of the dot in the top-left/top-right corner of the screen (after winning a round)
Goro is changed to Kintaro (NOTE: Due to space limits, “KINTARO” has been squished. Thus, Shao Kahn’s name, “SHAO KAHN” has been squished as well to fit the two bosses together.)
