LEGO Island

Game: LEGO Island (Windows, 1997)

WIN

A complete decompilation of LEGO Island (Mindscape, 1997) for Windows, English version 1.1. Its three binaries, CONFIG.EXE, ISLE.EXE, and LEGO1.DLL, are fully decompiled, and the ReproBit build, which uses the original compiler (Microsoft Visual C++ 4.2), reproduces all three retail executables byte for byte. Every push to the main branch is rebuilt and checked again, and publishes the executables along with per-function accuracy reports; work continues on naming, documentation, and code clarity without changing that result. The code is true to the original and only compiles for 32-bit Windows: the executables it builds replace the game’s own in its folder. The port to modern systems and the web, isle-portable, lives in a separate repository. For the byte-for-byte match, the repository includes the third-party Smacker and SmartHeap libraries, rebuilt partly from bytes of the retail binaries. Since September, 28 of its roughly 1,900 commits list Claude as a co-author, including the one that added ReproBit.
