Castlevania: The Adventure DX

Hack of Konami GB Collection Vol. 1


Castlevania: The Adventure is a fan favorite Game Boy game that was included in Konami GB Collection Vol. 1. That compilation did provide a much needed color injection, however it was full of weird color choices and incorrect overlays on backgrounds resulting in a marred experience. This release intends to correct as many of those flaws as possible, increase the quality overall, and make the game a dedicated stand-alone experience. Changes include:

  • Almost every enemy sprite has been re-colored in some way.
  • The main character sprite has been redrawn and re-colored.
  • The fully-powered whip fireball was given actual fireball colors.
  • Candle color was changed, and the design was reduced in size.
  • Color palettes for every level were altered to make the game more realistic, also resulting in better blending of objects into backgrounds.
  • Health bar was changed to a solid red rather than a color changing system, consistent with other Castlevania titles.
  • Inclusion of the “autoboot+speed+whip hack” by richirobot (with credits to tidi, hiro1112 and Ugetab) here.
  • Removed the ability to reboot the game to the selection menu using Start+Select+A+B.
  • Removed the ability to go back to the game selection menu at the title screen by pressing Select.

Hopefully this provides an experience more consistent with other “DX” quality releases. This was an excellent project for learning the ropes of Game Boy debugging, with the goal to contribute more to the colorization of DMG-only releases.

With that said, it couldn’t have done it without the assistance of Xenophile, Specialagentape, and MojoDodo. Big thanks go out to them, with hopefully more to come.
