Personal blog by Snow (git.2ki.xyz/snow) at datagirl.xyz. Posts focus on retro x86 / DOS systems, emulator internals (DOSBox, 86Box, PCem, DOSEMU), and the kind of low-level detective work that involves disassembling COM files and writing INT 06h exception handlers in NASM.
Code samples for posts live on a self-hosted Gitea-style forge at git.2ki.xyz.
