I miss a mkfile for 9front; as it uses SDL, it can be built with 'npe', a tiny POSIX compat library. There's a native one OFC, but having both it's interesting. If you like UXN, uxnasm it's becoming deprecated as the 'drifblim' ROM works as a .TAL->.ROM assembler itself without being bounded to any OS. Just port UXN, everything else can be compiled with drifblim. Even the big oquonie ROM, as they wrote a truncate(1) compatible tool too.

Drifblim: https://git.sr.ht/~rabbits/drifblim

Precompiled. You can use 'uxn2 drimblim.rom drifblim.tal drifblim-new.rom' to get a newer one

BTW their subleq implementation under UXN it's faster than the Perl one, a great job:
