openSA: reimplementing the GTA San Andreas runtime

openSA is an early C++ reimplementation of the GTA San Andreas runtime built on librw. It parses original IMG, IDE, IPL, model and texture data, and supplies viewers for streaming world geometry. The author documents comparisons with the owned 1.0 US executable while noting that the result is not yet a playable game.
