PPSSPP

The software emulates the PlayStation Portable, allowing users to run PSP game ROMs on a wide range of devices including Android phones, iOS tablets, Windows PCs, macOS computers, and Linux systems. It renders games at high‑definition resolutions, supports texture upscaling, anisotropic filtering, and optional post‑processing shaders to adjust visual appearance. Users can map controls to on‑screen touch interfaces, external gamepads, keyboards, or other input devices, and the emulator provides save‑state functionality for pausing and resuming gameplay at any point.

It is targeted at PSP owners and retro‑gaming enthusiasts who want to play their existing library on modern hardware without the original console. The emulator also enables transferring save data from a physical PSP, preserving progress across platforms.

The project is released under the GPL 2.0 (or later) license, is open source, and is maintained as a stable, free‑tier application. Contributions from the community are encouraged, and regular releases add bug fixes and compatibility improvements.
