BootlegGames Wiki

The BBD platformer engine refers to a game engine used in several platforming games on the Game Boy Color that are confirmed to be or otherwise have signs of being developed by BBD and/or Sintax. A telltale sign of a game using this particular engine is that pressing the left or right direction buttons and the jump button at the same time will sometimes result in the jump being cancelled.

    • New Crazy Arcade (新瘋狂阿給 泡泡堂) - Basic hack of Zook Hero Legend 3 that replaces graphics
    • Metal Slug X - An extensive hack that replaces the Zook player character sprite with Trevor Spacey from Metal Slug 4, uses entirely different graphics for levels, hazards, and enemies, and removes all menus for selecting a boss and saving/loading game progress, opting to simply have 9 linear levels instead. It also removes health and energy capsules and replaces the ability to gain weapons from bosses with item drops that allow you to use weapons temporarily. Consequently, this also led to the removal of the subscreen from the original game that allowed you to manage items and select a weapon to use, replacing it with a simple pause function
