I have a desktop and a steam deck. I would like to setup some old games I have on disc on the desktop. Then compress them and decompress on my Steam Deck without doing the full install again. I understand that with wine/proton prefixes they should be installed to a "fake c:/ windows hierarchy" can I just compress that and copy to a different Linux machine? Does it save which proton version was used? If I use something like Lutris or bottles can I import into them?
The registry is one of the reasons I was thinking I would need separate prefixes that I can copy. But, I also understand that games that actually use the registry are few and far between. If I actually come across one that needs registry edits I can just pack that differently.
