Final Doom Action Replay Codes (NTSC-U)
This page contains Action Replay cheat codes for Final Doom (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 Action Replay 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 Final Doom Guides Index and choose a different section.
