i wonder if you could make a useful DOS executable with just emoji

This title could be clearer and more informative.Try out Clickbait Shieldfor free (5 uses left this month).

A Mastodon thread exploring whether a functional DOS executable can be constructed using only emoji characters. The author analyzes UTF-8 emoji byte sequences and maps them to x86/8088 opcodes, discovering that certain emoji (like the frog 🐸, encoded as F0 9F 90 B8) decode to useful instructions such as MOV AX, IMMEDIATE. The thread walks through building a 'Hello' printer to CGA video memory using only emoji-encoded instructions, leveraging DOS PSP initialization tricks, undocumented opcodes, and size-coding demoscene techniques. The author proposes an emoji-based LLVM backend as the ultimate goal.
