Great to see a new version of this!
Can you use an IEC device to load SID files instead of having to bake them into a disk image? Thinking of using my Ultimate 1541's internal IEC device.
I'm using all Kernal routines for the drive so I assume some of it probably works. (like the load/saving) Testing locally in an emulator it seems the directory is blank if I set to an IEC device. I'll have a look if that's an easy fix, the drive stuff is probably the oldest part of the tool. :) I only have space for about 60 filenames from a directory.
After doing some more tests. If I put the sidlab program in a folder with some sid files and set that as the IEC device folder it works.
I can load/save them and also config files. So the main part seems to work.
The directory listing looks a bit weird because I don't have support for caps letters or anything so I can look into that. Is this what you were looking for?
