## Introduction
PPSSPP is a PSP emulator created by Henrik Rydgard, one of the original developers of the Dolphin emulator. It focuses on speed and portability, running on everything from high-end PCs to low-power Android phones. The project has been actively developed since 2012 and supports the vast majority of the PSP library.

## What PPSSPP Does
- Emulates the PSP's Allegrex MIPS CPU with a JIT recompiler for fast execution
- Renders PSP graphics via Vulkan, OpenGL, or Direct3D with resolution upscaling up to 10x
- Supports ad-hoc multiplayer over local network or the internet via a relay server
- Provides save states, fast-forward, and customizable on-screen touch controls for mobile
- Handles ISO, CSO, and CHD game formats with drag-and-drop loading

## Architecture Overview
PPSSPP uses a JIT recompiler that translates MIPS instructions to the host architecture (x86-64, ARM64, or RISC-V). The GPU emulation translates PSP GE commands into Vulkan, OpenGL, or Direct3D calls. A shader translation layer converts PSP's fixed-function pipeline to programmable shaders. Memory management and HLE (High-Level Emulation) of PSP OS functions keep compatibility high without requiring firmware.

## Self-Hosting & Configuration
- Download from ppsspp.org for Windows, Linux, macOS, Android, or iOS
- No firmware or BIOS required; PPSSPP uses HLE for system functions
- Place ISO or CSO game files anywhere and browse to them from the UI
- Configure Vulkan backend and resolution scaling under Graphics settings
- Set up networking for multiplayer via the built-in ad-hoc server or PPSSPP relay

## Key Features
- Runs on six platforms including Android, iOS, Windows, Linux, macOS, and UWP
- Texture upscaling and replacement for enhanced visuals
- Built-in post-processing shaders (FXAA, CRT, bloom)
- Rewind and fast-forward for gameplay convenience
- Gamepad, keyboard, and touch control support with fully customizable layouts

## Comparison with Similar Tools
- **RetroArch** — multi-system frontend that includes a PSP core, but PPSSPP standalone offers better PSP-specific features
- **Vita3K** — PS Vita emulator targeting Sony's newer portable; earlier in development
- **PCSX2** — PS2 emulator covering a different Sony platform with higher hardware requirements
- **Dolphin** — GameCube/Wii emulator by a co-founder of PPSSPP; different console family

## FAQ
**Q: Does PPSSPP need a PSP BIOS or firmware?**
A: No. PPSSPP uses High-Level Emulation to replicate PSP system functions without proprietary firmware.

**Q: Can I play multiplayer games?**
A: Yes, ad-hoc multiplayer works over LAN or internet using PPSSPP's built-in networking features.

**Q: Does it work on mobile?**
A: Yes, PPSSPP runs on Android and iOS with touch controls and performs well even on mid-range phones.

**Q: What game formats are supported?**
A: ISO, CSO (compressed ISO), and CHD files. You can also load from extracted folders.
