Hi, sorry for the delay, I'll test and pull this in eventually, I just have been busy. Thanks for contributing back :)

No problem, take your time and keep up your excellent work on fs-uae. :-)
Some additional info for the patch: Right now the flags are enabled only if the archive is identified as an amiga archive. Unfortunately there are many older amiga archives with header level 0 out there which can not be identified. In theory we could also get flags from these archives but the result might be wrong. Perhaps you will find a solution. ;) Documentation is here (if you don't already know): http://homepage1.nifty.com/dangan/en/Content/Program/Java/jLHA/Notes/Notes.html

I started making some extract-tools which can automatically create .uaem-files for fs-uae, but there is still a lot of work to do. Maybe some day we see something similar for fs-uae-launcher... :-)

You should rebase your pull request branch to remove the merge commits.

Probably should add a default value where so it does not fail when OS identifier is not recognized, e.g.:

create_system = os_identifiers.get(os_identifier, "")

[sonnenscheinchen]

Hm, it wouldn't really fail. It would be set to None, which may be considered wrong because in fact some system has created the archive. :-) I let it set to an empty string as you suggested.

This pull request has been open for an embarrassingly long time, will look over again and aim to merge and do a 0.3.0 release.

On another note, I've also set up automated builds via Github actions, so binary wheels for Windows, macOS and Linux are not created (and I upload them to pypi as well).
