The phrase refers to the process of acquiring and installing PlayStation Portable (PSP) game files on Apple iOS devices using the PPSSPP emulator. This involves finding compatible game files, often in ISO or CSO format, and transferring them to an iOS device running the emulator software. This approach allows users to experience PSP games on their iPhones or iPads.
The ability to play PSP titles on iOS offers several advantages. It provides access to a vast library of games that were originally designed for a dedicated handheld console, expanding the gaming options available on Apple devices. Historically, this capability emerged as emulator technology matured and iOS devices became more powerful, enabling them to handle the processing demands of emulating PSP games.
