Grandia II Codebreaker Codes (Japan)
This page contains the Codebreaker Codes that I have available for Grandia II, a game for Dreamcast. 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 Dreamcast console will have to use an actual Codebreaker device instead.
If you don't see the code you're looking for on this page I recommend you return to my Grandia II Guides and Walkthroughs and choose a different section.
