If you want to practice on a specific stage or make single stage score attempts this code may be useful to you.

To access the Stage Select menu: While holding the B button press DOWN on the D-Pad four times while on the Anniversary or Title Screen (doesn't work in any of the menus) A sound effect will play if entered correctly. Now just start the game as usual.

Remember, you can reset the game by pressing START+SELECT+A+B during gameplay or the score tally. You will have to re-enter the Stage Select code if you want to use it, but your selected difficulty level and player speed are preserved.

Thanks for still playing Dangan GB, it's been a fun six years! Have you checked out the sequel yet?
