The phrase represents the act of acquiring, specifically through digital means, the action-adventure game Grand Theft Auto: San Andreas for play on the Sony PlayStation Portable (PSP) handheld console. It combines a well-known video game title with a method and platform for its distribution and enjoyment.
Acquiring software in this manner offers immediate access and portability. For older gaming platforms like the PSP, it allows continued access to titles that may no longer be widely available in physical retail formats. However, users must be aware of copyright laws and the potential risks associated with unofficial sources, which could include malware or corrupted files.
