Hack of Konami GB Collection Vol. 4


These hacks converts the Konami GB Collection Vol.4 (Europe) game into standalones ROMs by autobooting straight into the games.

The games are:

  • Antarctic Adventure
  • Castlevania II: Belmont’s Revenge (no speed hack, just the autobooting)
  • Gradius II: The Return of the Hero (aka Gradius: The Interstellar Assault in America and Nemesis II: The Return of the Hero in Europe on their GB releases)
  • Yie Ar Kung-Fu

You just have to use one ips patch depending on the game you want to autoboot into.

Created by reverse patching the dACE ( ) and Silver X ( ) patches for Castlevania II, so credits to them too.

Known issue:

  • Soft-resetting any of the patched games (A + B + Start + Select) will take you to the actual Konami GB Collection Vol.4 title screen.

ROM / ISO Information:

  • Database match: Konami GB Collection Vol.4 (Europe) (GB Compatible)
  • Database: No-Intro: Game Boy/Color (v. 20210227-015730)
  • File/ROM SHA-1: 4C0C9E9CBA36BFE5588E2A2DC799D207AFD1321E
