The rebuilt executable

uv run build compiles decomp/ and glue/ (reusing match's objects), the icon (BRCC32) and links them with TLINK32 1.50, Borland C++ 4.5's linker, into build/rebuild/zoombi32.exe with a map.

• Linked in the original's order (each source by its first marked function; glue/ where the code it stands in for was), with -Tpe -aa -c, the result has the original's six sections at the same addresses, the same export (__GetExceptDLLinfo) and the same icon resources, byte for byte.
• Its imports differ only where its code does: DebugBreak and the Interlocked functions replace the original's inline assembly, and GetVersionExA came from Apple's QuickTime glue, which glue/quicktime.cpp stands in for.
• It runs in the VM: uv run vm run --exe build/rebuild/zoombi32.exe. --trace LOG makes QEMU log the executable's code as it runs, and uv run trace LOG names the functions from the map; after a crash, the last one is where it happened.
• The game refuses to start while the global atom Zoombini exists, which a crash leaves behind: reboot the VM before running again.

A near-miss can be the bug: when the rebuild crashes, look at what differs in the functions it was in.
