I hate this version
For this version: Nothing! The SNES version is really weak. Even with nice graphics really next to the arcade, The Mortal Kombat for this platform has no blood and violence. The genesis version you had to make a code to do it.. The best 16-bit version for that game is SEGA CD. the Pc version is ok too.
No Blood, No Violence. It lost totally the sense of this game.. SNES version is really bad for this.
The Bottom Line
Play The Genesis version with blood secret code, Sega Cd or DOS. but don't play the snes one
