# Sid Meier's SimGolf: source reconstruction of the English 1.03 release

> Sid Meier's SimGolf reconstructs C and C++ source for the English 1.03 game's executable and three DLLs, comparing recompiled functions with the originals. The author reports instruction matches for every function, while the final linked files retain differences. Kaitai Struct definitions document several save, course, golfer and sprite-bank formats.
