Note: This derived from the Z80-Retro-disk-maker repo.
This will download the games from Anna Christina Naß's games repo here: https://git.imzadi.de/acn/vt100-games and build a filesystem suitable for use on the Z80 Retro!
By default, a make burn will overwrite the filesystem on drive E of your SD card.
Here is a capture of me running this on my home system (just type make and then make burn):
