Found one interesting issue - there are .ISO files where root catalog is read but you can't access neither files nor directories there. And what's very noticeable is the letter's case - filenames have mixed case, not uppercase-only. These are the ISOs:

https://cdimage.debian.org/mirror/cdimage/arc … usinesscard.iso
https://cdimage.debian.org/mirror/cdimage/arc … 386-netinst.iso
(The installation disks also behave the same, but they need jigdo-lite for downloading and I suppose no-one will care)

...

My setup: PicoGUS HW v2.0, firmware v3.7.1, DOS 6.22

Just to be very clear - this is not a heart-breaking issue for me. Just noticed and reported it, in the name of the common good.

I suppose the question is whether they are incompatible with the PicoGUS emulation or with DOS 6.22, the images were made in 2008 and may use features beyond DOS 6.22's capabilities (EG not including 8dot3 backwards compatibility). Did you try a physical drive to see if the images work correctly?
