  "description_en": "Restores C source for Fallout 2’s Windows engine from the original binary, keeping as close to the original as possible with all its imperfections. The resulting fallout2-re.exe is a drop-in replacement for fallout2.exe that runs on the user’s own GOG or Steam copy. README says a few non-essential functions remain undecompiled; the code became the basis of the separate Fallout 2 Community Edition, and its author calls wide publication legally questionable.",
