Johnny Test Codebreaker Codes (USA)

This page contains the Codebreaker Codes that I have available for Johnny Test, a game for NDS. If you are playing on an Emulator you can usually input these codes rather easily by accessing a tab at the top of your Emulator; those of you playing on a physical NDS console will have to use an actual Codebreaker device instead.

For those of you playing NDS on an Emulator, I have you covered. There are a couple of popular NDS Emulators, many of them I have guides for which will show you how to use and add codes. Check out my RetroArch, MelonDS or DeSmuME guides for more information about how to use these codes on the Emulator of your choice.

If you don't see the code you're looking for on this page I recommend you return to my Johnny Test Guides and Walkthroughs and choose a different section.
