Warning on "Xtreme" / "Platinum" Editions: Be very careful downloading files labeled "GameShark Xtreme," "Platinum," or "Day 1." These were often third-party hacks or unofficial compilations distributed on shady forums in the mid-2000s. They are rarely "verified" and frequently contain corrupted save files or, in rare cases, malware embedded in PC-side tools.

If the file structure of the disc is altered—even slightly—the specific memory addresses the codes target might be wrong. A verified Gameshark PS2 ROM guarantees that the codes found in old text files across the internet will actually function as intended.
