Monster Rancher - Monster Modifier Codebreaker Codes (NTSC-U)

This page contains CodeBreaker cheat codes for Monster Rancher (NTSC-U) for the Playstation 1. Depending on if you're playing this game on a physical console or an emulator will determine how you use the codes found on this page. People using a physical console will need to purchase a physical CodeBreaker device to use the codes.

Anyone who is using an Emulator will have a much easier time getting these codes to work (assuming your Emulator supports them). One of the most popular Emulators for the Ps1 is ePSXe and if you'd like to learn how to use the codes on this page for that Emulator, check out my how to get cheat codes to work with ePSXe guide. If you don't see the code you want on this page I recommend you return to my Monster Rancher Codebreaker Codes and choose a different section.

If you don't feel like using this code I recommend the Frozen Monster Modifier or the Frozen Monster Modifier (#2) Codes instead. All of these will allow you to 'create your own monster' but (imo) the Frozen codes require less steps.

Note: To use this code you need to make sure the monster you want to keep normal is frozen before you activate the code. When you activate the code make sure it's with whatever monster you want to change. Visit the Market and buy a Dino once the code is active and freeze it. Then buy another Dino in the market and freeze it before turning the Gameshark OFF. Combine the two Dinos to make a full breed of whatever you programmed via this code.
