Mortal Kombat 4 - Background Modifier Action Replay Codes (USA)
This page contains the Action Replay codes that I have for Mortal Kombat 4 (USA), a game for the Nintendo 64. If you are playing on a physical N64 console then you will need to purchase a physical Action Replay device to use the codes you find on this page and website. From what I have read and seen both of these cheat devices have cross compatibility.
For those of you out there using an Emulator such as Project 64, you can typically add cheats by clicking on a tab at the top of your Emulator that will lead you to a section where you can add codes. Anyone who is using the Project 64 Emulator should check out my How to Setup Codes on Project 64 Guide for more information on how to get cheats working.
If you don't see the cheats you're looking for on this page I recommend you return to my Mortal Kombat 4 Action Replay Codes page and choose a different section.
Note: You must use the 'Restart This Match' code with this one in order for this to work. Round 1 will always load a black background, pause the game and restart the match to get the background you want.
