This repository is a work-in-progress to create a simple unpack and packing tool of .ucas and .utoc files. If this succeeds, it would make it possible to create mods for games that use the new .ucas and .utoc file format.

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.
