I am playing MK4 when i am too angry for like more than 10 years. No one can knows better than me this game's graphics. And i surely can say this that who edited MK4.exe is killed Raiden's or other fighter's special effect lights. Raiden's electric shoot or fly doesn't cause blue/white-ish light on opponent's and his front. My English is bad but i hope i explained it well. There is 3D Patch which made by fan in 2000s. It is free and has more good restoration than this version. With that patch, special effect lights getting more vibrant and other things.. Then the game look overall more high resolution. Don't waste your money and download just random 30MB zip archive from internet.
