That's pretty cool! It reminds me of a similar project I did called z80e, which is an emulator for TI calculators [0]. It uses unicode braille to "render" the screen onto a terminal. Doesn't work on the VT220, though, for obvious reasons. [0] https://github.com/KnightOS/z80e https://github.com/KnightOS/z80e

  Fascinating! I'm reading the source code of z80e (tui.c). Your idea of using unicode to display pixels is very interesting. I imagine a fallback mode for libsixel for terminals not sixel-compatible (or the opposite). I try ton compile but it fails (first because scas was missing and now I have an "a2x: not found" in scas). I appreciate a lot the "multitarget rendering" (emscripten, tui, sdl...).

    a2x should be provided by the asciidoc package on your distribution. It's used to compile man pages. I'd merge a pull request adding libsexl support!

      > a2x should be provided by the asciidoc ... Yes, thank you (I'm on Debian). I know a bit more after reading the wiki. I will follow the instructions for the sdk. > I'd merge a pull request adding libsexl support! Cool! I'm discovering the new world of custom tools for TI (KnightOS, Axe Parser, OS2...). I will look at the SDL UI to see what I can do. BTW z80 is good target for superoptimization and I'm very impressed by your toolchain and its history :)

I remember someone at school wrote a program to inspect a remote Decstation 3100 (1024x864x1) screen on a vt320. Frequently people were running X with "xhost +".
