The full story
Flight Simulator 95 and 98 crash on 64-bit Windows with divide-by-zero exceptions in their 2D and 3D window handling. The poster had tried DxWnd, but the games were unplayable. They gave both games to Claude Code, which patched WINDOW.DLL and G3D.DLL for FS95 and worked.
While debugging FS98, Claude found the real culprit was the game EXE files, which contain a routine for handling faulting divisions, and used that to trace the same issue in FS95.
