Need for Speed: Underground Action Replay Codes (UK)
This page is dedicated to all of the Action Replay Codes that I have for Need for Speed: Underground (UK) on the Nintendo Gamecube. If you're looking for the Need for Speed: Underground (US) Action Replay Codes then I recommend that you follow the link provided to be taken to that page instead.
When it comes to using the codes on this page/website there's two good Emulator choices available to you. You have RetroArch which is one of the more popular multi-system Emulators and then you have Dolphin (recommended) which just emulates GC and Wii games. Follow the link provided to learn more about using these codes on the Emulator of your choice.
