Decompilation

The LEGO Island decompilation is an ongoing project to decompile LEGO Island's binary game code back into C++ code.

The project started in April 2023 when MattKC began a small project to decompile ISLE.EXE, the small front-end to the game. It soon evolved into decompiling LEGO1.DLL, which contains the vast majority of the game code, and now has a small team behind it making regular progress.
