sjasmplus

This is a small Z80 assembler program that just puts some colored lines on the ZX Spectrum's screen. The intention is to use this as a kind of tutorial for DeZog (Z80 debugger).

dsk-lua is a library which lets you write/read data to a DSK file (Amstrad CPC Diskette format), for use into SJASMPlus

My solutions for https://adventofcode.com/ programming mini puzzles - written mostly as sjasmplus script (to exercise the tool and collect ideas for future development of the script language, not because it's a best choice for the task, quite opposite)
