Escape Velocity Nova: an engine reimplementation guided by decompilation

evnova-decomp reimplements the Escape Velocity Nova engine in C++23 and SDL3 using data from a local Windows Community Edition installation. Its research notes cover resource formats, missions and gameplay behavior, while Ghidra-based tools support comparison with original functions. The author reports a playable storyline but notes missing features and timing differences.
