These hacks converts the Konami GB Collection Vol.1 (Europe) game into standalones ROMs by autobooting straight into the games.

The games are:

• Castlevania: The Adventure (no speed hacks, just the autobooting)
• Konami Racing (aka World Circuit Series in America and The Spirit of F-1 in Europe on their GB releases)

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