Believe it or not, the highlighted value there is key to unlocking maximum health in a Dead Space 2 save file.
The newest, PS3-based incarnation of the Game Genie doesn’t share much of a lineage with the original line of similarly named, cartridge-based cheat devices nearly ubiquitous in the 8- and 16-bit eras; manufacturer Hyperkin picked up the rights to the name when Galoob’s original trademark recently lapsed. It doesn’t share exactly the same functionality as its namesake either. While the old Game Genies actively patched the ROM code being loaded from the game cartridge, the PS3 Game Genie is actually just a computer program that lets you decode and modify PS3 save files stored on a standard USB stick.
But one thing the old and new Game Genies share is the ability for a determined, patient hacker to create their own cheats by diving in to the vagaries of the hexadecimal code. While most users will probably be satisfied clicking checkboxes to activate pre-built cheats like maximum health and full game unlocks (just like most users of the original Game Genie were satisfied copying down codes from the included booklet or game magazines), the Game Genie software also offers an Advanced mode that allows for more direct save file manipulation.
The Game Genie documentation doesn’t offer much guidance on how to use this advanced editing option, so I reached out to Hyperkin Project Manager Wayne Beckett (a veteran developer of previous cheat devices like the Action Replay and Game Shark) to explain the basics of how the PS3 save file hacking works.
