Matching decompilation
Underworld Exhumed
Category: Games & game engines · Type: Reconstruction
Target: Ultima Underworld I & II · C / native / WASM
A byte-matching decompilation of Ultima Underworld I & II that rebuilds the original DOS EXEs, plus native and WebAssembly ports checked against recorded DOS sessions. Same games as UnderworldGodot, different approach (matching decomp + port vs Godot recreation).
Relationship
Independent reimplementation
Evidence scope
The upstream README documents byte-identical rebuilds of UW.EXE/UW2.EXE, native/WASM ports with accuracy CI, and an explicit no-game-data policy. Licence section separates MIT project work from proprietary-derived decompiled code. No REA involvement is claimed.
Know before you try
Repository ships no game data; native ports need the user’s GOG (or other legal) copies. Decompiled code is derived from proprietary EXEs — MIT covers tools/docs/structure only. Distinct from UnderworldGodot. We have not independently tested it.
Status
Matching decomp with native/WASM ports; accuracy CI
License
MIT (tools/docs/structure)
MIT covers project tools, documentation and structure. Decompiled code is derived from proprietary Ultima Underworld EXEs; the licence grants no rights in that original program. Game assets are not included.
