Tony Hawk's Underground Action Replay Codes (US)

This page is dedicated to all of the Action Replay Codes that I have for Tony Hawk's Underground (US) on the Nintendo Gamecube. If you're looking for the Tony Hawk's Underground (UK) Action Replay Codes then I recommend that you follow the link provided to be taken to that page instead.

If you are using the Dolphin Gamecube Emulator and struggling to figure out how to get these codes to work, look no further! Check out my How to setup Action Replay Codes on Dolphin or my How to setup Gecko Codes on Dolphin guides. Both of these can provide you the guidance that you need to get your codes working.
