DoDonPachi Resurrection

On Ship Select for iPhone Hit B type once then, A, B, C, A, B, C, B, C, A, B, C, A, C, A, B, C, A, B Hibachi will appear at the bottom to confirm the unlock. Alternatively, simply beat him normally in the game.

After you've beaten the game, you'll unlock the option to change the background music for the iPhone and Arcade gameplay modes. You can change the music via Sound Menu.

To enter the open 2nd loop of the game, you must collect at least 35 hidden bee icons, which can be revealed by firing the laser so that the FRONT edge of the beam passes over them (having it on and running over it from the side doesn't count) and not continue. Defeat Shooty on Stage 5 and select the top option when Longhena asks you the question. This will take you to the Open 2nd loop, featuring Taisabachi as the final boss at the end. This can also be achieved by finishing the first loop by not dying at all if you lack of hidden bee icons. If you get all 45 bee icons AND are on the hidden (Ura Route) when you defeat Shooty at the 1st loop end, selecting yes will take you to the Hidden 2nd Loop, which operates similar to the Open 2nd loop, only after Taisabachi is destroyed, Hibachi will appear to attack you. Defeat Hibachi to unlock it as a playable character.
