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?
I use Heroic Launcher, it supports GOG and the Epic Store, but adding DRM-free games to it is also as easy as Lutris.
I wonder if it would then be easy to backup the drm-free games to copy elsewhere…?
