Many players use the following codes within their .pnach file to force widescreen and attempt to uncap the framerate. Be warned: running the game at 60fps can cause "physics issues," such as Kratos falling through the floor or moving too fast, unless a specific physics decoupling patch is used.
If done correctly, the text on the screen will turn purple , indicating that Progressive Scan is active.
By running the game on a modern PC, you have surplus CPU power. The challenge is that the game is programmed to cap itself at 30fps. To override this, modders have created specific widescreen and framerate patches.
While you cannot do this on a physical PS2, you can achieve 60fps on a PC using a PlayStation 2 emulator (such as PCSX2). In the emulation community, the file format used to apply patches is called a file. This is the modern equivalent of a "cheat code."
