A cheat code is not a simple switch; it's a precise command that changes a specific value in the game's memory. When entering codes (which can be long strings of letters and numbers), one single-digit error can render the cheat useless or, worse, cause unintended side effects. A "verified" code, as frequently emphasized in official GameShark sources, is one that has been confirmed to work correctly. Using verified codes from trusted sources ensures that "Infinite Health" actually gives you infinite health, rather than corrupting your game's save file or causing it to freeze.

If you play on an original PS2 using Free McBoot (FMCB) and Open PS2 Loader (OPL), executing a GameShark ROM requires a bit more nuance.

Searching for "PS2 GameShark ISO" on Internet Archive is often the safest bet. Users curate these collections, and the files are usually clean.

If you run verified ROMs off a hard drive or USB stick on a physical PS2 via FreeMcBoot, you can use OPL's built-in cheat engine.

Trusted repositories like Vimms Lair or the Internet Archive are preferred for finding ISOs or codebooks.
