Picocal Luckfox Lyra

Here’s the current status of my migration of the x48ng emulator to Picocalc using a modified Luckfox Lyra board and its Linux from scratch modified. For now, only the Ncurses version works, but I plan to add SDL support as well. It’s already functional! Also I did it entirely without closed-source Windows tools, which was the biggest challenge! :)

Current issues and steps to replicate it: here
