DoDonPachi DaiOuJou: Black Label (2002)

Dodonpachi Dai-Ou-Jou: Black Label is a revised version of the original Dodonpachi Dai-Ou-Jou, released only six months after the original version. It features remixed gameplay with a number of refinements. Players are given the option at the start of their game whether to play a one-loop or two-loop game, with the one-loop option always giving players the ability to face off against hidden boss Taisabachi and true final boss Hibachi. The first loop is made noticeably easier, and players are able to keep their lives and bombs when entering the second loop. Several other bugfixes and adjustments to the scoring system lead to an overall smoother difficulty curve. The board also includes a full copy of the original game; arcade operators can choose which game to boot at startup.
