## What it is
PSn00bSDK is an open source homebrew software development kit for the original Sony PlayStation, providing a GCC-based C/C++ toolchain, libraries abstracting the console's hardware, and build/asset tools. It reimplements most core functionality of the official Sony SDK with extensions, enabling development of PS1 games and apps without proprietary tools.

## Use cases
- develop homebrew games for the original PlayStation
- build PS1 apps without the official Sony SDK
- port an existing PS1 codebase away from Sony tools
- program PS1 GPU, GTE, and CD-ROM hardware in C
- create CD-ROM disc images for PlayStation homebrew
- experiment with PS1 hardware like MDEC video playback

## When to choose
- you want a fully open source toolchain for PS1 development
- you're migrating an existing homebrew project off the official Sony SDK
- you need low-level control over PS1 hardware with C/C++
- you want active maintenance and modern build tooling (CMake) for PS1 homebrew

## When to avoid
- you're a beginner to console homebrew development
- you need a drop-in replacement for the official Sony SDK's higher-level libraries
- you require float-based math or high-level engine features out of the box

## Facets
- artifact type: framework
- maturity: active
- function: sdk, compiler, build-tool, graphics, game-engine
- domain: embedded-systems, developer-tools, cross-platform
- platform: windows, cpp, c, embedded
