Familiarize yourself with the PSP interface to decipher cheats for games like Grand Theft Auto: Vice City Stories. Information in this article applies to all models of the PlayStation Portable game system. How to Enter Cheats With the PSP Controller Sony's first portable system features a control scheme that is similar to the original PlayStation console with a few differences. Most notably, there's only one set of shoulder buttons, and there's an analog stick in addition to a directional pad. Here's a full anatomy of the PSP controls and how they are typically used in cheat codes: L1 and R1: These buttons are sometimes called triggers, bumpers, or shoulder buttons. When you see a code with R, R1, L, or L1, it refers to these buttons. D-Pad: Any code that includes directions (like Up, Down, Left, Right) is always entered using the D-Pad unless otherwise noted. Analog Stick: Some codes require directional inputs to be entered using the analog stick; however, this is rare, and it will be clearly noted in the cheat guide. Start and Select: Some codes require you to press Start to pause the game prior to entering the cheat. X, O, Square, and Triangle: These are the main action buttons, and they generally make up the bulk of cheat codes. The O button is alternatively called Circle.
