Lua for Watcom builds from 11th of January 2026

What's new:

• Increased stack size on LUA4G.EXE to prevent 'stack overflow!' error on more resourceful scripts.
• Resource management improvements to INFLATE.LUA and UNZIP.LUA scripts.
• UNZIP.LUA now allows users to specify a directory to extract to and which files in the zip to extract (or exclude) with similar parameters to the Linux version of unzip.

Known issues and limitations:

• Large memory model binaries (LUA16 and LUA21) cannot support a Lua table that exceeds 64k of memory (#7)
• Despite improvements, INFLATE.LUA is still too resource intensive to run on 16-bit machines (Lethja/lua-scripts#1)
  • For 8086 DOS pkg.exe from the SvarDOS repository can be used like a zip extractor.
    Example usage: pkg unzip file.zip

File contents:

• WLEee5b6.zip - Watcom Lua Executables: A zip file containing binaries for each platform.
• WLI89774.zip - Watcom Lua Images: A zip file containing floppy disk images
  (for direct use on floppy drives, 86Box, MiSTer FPGAs AO486/PCXT cores, etc...)
  • 1.44mb disk images containing binaries for each platform
  • 160kb disk images containing just LUA16.EXE

Check binary native targets and binary compatibilty matrix to see which executable(s) can be used on your system.
