    Https://web.archive.org/web/20230315024557/http://www.columbia.edu/~em36/ntvdmx64.html Or just run dosbox for full and isolated emulation. Full circle, there's also djgpp and openwatcom for semi-modern retro development. https://www.delorie.com/djgpp https://openwatcom.org I collect retro compilers, programming books, software, and hardware. - Source: Hacker News / about 1 year ago
  • I want to start learning how to program DOS games
    I recommend using Open Watcom, particularly the Open Watcom V2 fork, to target 32-bit protected mode DOS, rather than 16-bit real mode. Source: almost 2 years ago

NASM mentions (3)

  • How to improve at x86/C?
    Try https://nasm.us/ as a modern way to use assembly. Source: about 1 year ago
  • Help needed for asm related project
    Assembly is machine specific, have a look at NASM for a more generic assembly language. https://nasm.us/. Source: about 1 year ago
  • vcpkg now (finally) has site with search functionality
    I have a weird problem: when I try using vcpkg on my work laptop, it cannot download nasm. Instead of nasm, I get an HTML page that explains that I am kept safe and secure by CSIS who blocked downloads from this dangerous domain. Vcpkg barfs on the HTML file (as it should).
