PSXLib is a library for homebrew PlayStation 1 development. This project aims to implement fully free and open replacement to proprietary standard library from Psy-Q SDK.
PSXLib doesn't provide its own MIPS toolchain though, it is meant to be used with Psy-Q CCPSX compiler and corresponding tools.
Currently PSXLib contains only the most basic functionality:
- GPU initialization and OT management
- Uploading TIM images to VRAM
- Rendering basic 2D primitives - sprites, dots and lines
- Rendering text
- Reading controller input
- TTY output (printf)
PSXLib API doesn't imitate Psy-Q one-to-one. I tried to design it in a simpler and more consistent manner. Some functions are inspired by Blade's PSX library.
PSXLib is written in ANSI C with part in ASPSX assembler.
libgs from Psy-Q is a closed-source abandonware, so it can't be patched or updated. Other homebrew libraries out there often require non-standard toolchains and specific environment setups, while I wanted something simple and CCPSX-friendly. PSXLib can be used with other Psy-Q functionality, such as CD-ROM functions, until they are reimplemented from scratch.
A simple usage example can be found in the demo folder. Keep in mind that this repository doesn't contain third-party utilities needed to build it. You can download a prepackaged version for Windows from Releases page, but you still need to install Psy-Q SDK by yourself.
