DoDonPachi DaiOuJou (PlayStation 2)
A few extra menu options exist in this game. They don't work correctly anymore, unfortunately. The sound test options only allow you to play a single song and SFX. The Debug Options menu doesn't seem to do much either. If HIT DISP is set to on, it will make your craft invisible but you can still get hit. The question marks in the Debug Option menu can't actually be normally seen even when entering the menu.
Apply the below code to enable these options.

A leftover menu from the arcade version. The menu doesn't work correctly anymore.
