Gradius Generation - Manual Mode CodeBreaker Codes (Japan)

This page contains CodeBreaker cheat codes for Gradius Generation (Japan). If you're playing on an emulator you can usually input codes very easily by accessing a tab off the top of the toolbar. Anyone playing on a physical Gameboy will need to purchase a physical Codebreaker device to use these codes.

If you're using an Emulator and you can't figure out how to make these codes work, you're in luck! You can find guides for RetroArch, mGBA, VisualBoy Advance (Depreciated) and VisualBoy Advance-M on my website. Follow the link(s) provided to learn more about how to make these codes work on the Emulator of your choice.
