Hack description

Standalone Gameboy Color version of Probotector / Contra Operation C

Convert Konami GB Collection Vol.1 (Europe), that is a collection of 4 games, into a standalone Probotector / Contra Operation C ROM by autobooting straight into the game.

Therefore use the ips-patch.

Or do it yourself:

Use a hex-editor.

Replace "3E 01 EA A0 C0 EA A1 C0 3E 08 EA A1 C0″ at hex-address 18BA8 with "3E 09 EA A1 C0 3E 03 EA B0 C0 EA A0 C0"

Note: Instead of "03″ you can use

"01″ for autobooting into castlevania 1,

"02″ for autobooting into konami racing.

All credit goes to users dACE and RichterSnipes. Special thanks go to user SCD for inspiration.

Unfortunately it is not possible to autoboot into the last game "gradius" by this procedure.

A simple effort, but much appreciated	Supergamerguy	2021-07-29	Version 1.0
I don't have a lot to say for this one, but I greatly appreciate the author making the colorized version of Operation C more accessible to people outside of PAL regions. It's a lot more fun playing this game with full color, and not having to go through a menu to select it is cool too.
