OpenZT2 — Zoo Tycoon 2, rebuilt

Field notes

The project divides its reconstruction work into disassembly, reverse engineering, asset conversion, and gameplay reimplementation, with progress recorded separately for each phase. Its homepage reports 19 of 19 asset-format families converted and 145 of 163 gameplay capabilities implemented, while two capabilities remain blocked. The renderer translates original D3D9 Effects and pass state through vkd3d-shader and MojoShader for Bevy. The project says the eventual release will use the player’s own Zoo Tycoon 2 files rather than distribute original game content.
