MLB 2004 Codebreaker Codes (NTSC-U)

This page contains CodeBreaker cheat codes for MLB 2004 (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). There are three popular choices for Emulation on the PS1, RetroArch, Duckstation and ePSXe. Follow the links provided to learn more about how to add/use these codes with the Emulator of your choice. If you don't see the code you want on this page I recommend you return to my MLB 2004 Guides Index and choose a different section.
