Four codes only work on PSP
The multiplayer unlock codes exist because the PSP version had wireless multiplayer. The PlayStation 2 port dropped it, and those four codes with it.
3D Era 2006 Vice City
Vice City, 1984. Victor Vance needed money for his brother's medicine. Vice City Stories is the last Grand Theft Auto Rockstar Leeds made for the PSP, released in October 2006. It runs two years before Vice City, and stars Victor Vance, the brother Lance talks about and the man who dies in the opening minutes of the 2002 game. Vic is discharged from the army in the first hour and spends the rest of it building an empire he never wanted, because his brother Pete needs treatment he cannot afford. It reached PlayStation 2 in March 2007.
