# libgpu2: reconstructing a PlayStation 2 Graphics Synthesizer model

> libgpu2 reconstructs Sony's 1998 PlayStation 2 Graphics Synthesizer software model from 23 ELF32/i386 objects as buildable C++. The project documents the recovered pipeline and compares VRAM output from replayed graphics streams with the original model and PS2 hardware. The author reports bit-identical output to the original model on its dump corpus.

## Requirements & limits

- **Prerequisites:** For the native build: a C++ compiler, libX11, Python 3 and Pillow.
- **Prerequisites:** The 1998 byte-comparison build additionally requires a 32-bit userland and the era compiler setup.
- **Limits:** Byte-level matching remains incomplete; original objects and graphics dumps are local inputs.
- **License:** No licence file in the repository.
