psxgs

This is a heavily WIP re-implementation of Sony's libgs Playstation 1 high-level graphics library. It aims to be API-compatible with the official library so that old games and SDK sample code can be ported over.

Currently, it's not even at the point of rendering a TMD triangle yet.

Once reasonably complete, I hope to merge it into Psn00bSDK.

Building

1. Obtain a cross-compiler which supports at least C11. I'm using one built using crosstool-ng at commit bbb0db2880d5e7600e176fc8025f0add9ef85eb9. Simply follow the instructions on the crosstool-ng site to build and install it, then do cp mipsel-sony-none.config .config and ct-ng build. Copy the resulting toolchain to toolchains/.
2. Follow the Psn00bSDK guide to build and install the SDK, then run make in the directory you cloned psxgs into.

Building samples

After building the library, cd samples && make will create a PSX .exe executable for each sample. Any half-decent emulator should be able to run these directly.

Usage

Add /path/to/psxgs/include to your build system's system headers (for GCC, this can be done using -isystem), as well as /path/to/psxgs/lib/ to your build system's static library search path. Finally, add -l psxgs to link against the library. Note that it has to be placed before -l pxsgpu and -l psxgte, otherwise the linker won't find the symbols psxgs needs.

In case of problems, it may be helpful to reference the Makefiles under sample/.
