Codejunkies vs. GameShark Codes for GBC: Key Differences & Modern Usage

They are not the same. They represent different ecosystems—one was a hardware product, the other a code database.

NaturePhysical cheat cartridge hardware (InterAct / Mad Catz)Website / Community database of cheat codes
Code FormatProprietary (often encrypted/obfuscated for GS hardware)Standardized Raw / AR / GS / CB formats; user-submitted
Device RequiredGameShark cartridge (v1–v3, Pro)Any device supporting the format: GameShark, Action Replay, GameBooster, Flashcart (EZ-Flash, EverDrive), Emulator
AvailabilityFixed ROM on cartridge (limited updates via PC link cable)Constantly updated online database; thousands of games

Practical Use Today

  • Find codes on GameHacking.org (successor to Codejunkies/GS Central).
  • Export as .cht (RetroArch/mGBA) or .xml (EZ-Flash Omega).
  • Flashcarts apply codes in real-time on real hardware—no GameShark cartridge needed.

Codejunkies was the source; GameShark was one target device.
