Operation C Gameshark Codes (USA)
This page contains all of the Gameshark codes I have for Operation C (USA), a game for the Game Boy handheld console. If you are playing on a physical Game Boy/GBC then you'll need to purchase a physical Gameshark device to use the codes that you find on this page.
For those of you who are using an Emulator such as the VisualBoy Advance, you can typically add cheats by clicking on a tab at the top of your Emulator. This will lead you to a section where you can add codes or edit existing ones. Anyone who is using the VisualBoy Advance should check out my How to Setup Codes for GB/GBC on the VisualBoy Advance Guide for more information on how to get these cheats working.
If you don't see the code you are looking for on this page you should return to my Operation C Guides Index and choose a different section.
