I'm considering buying a steam deck, which runs Linux, but also wish to play Mariokart 8 Deluxe. I've seen it be done, so I know its possible, but does anybody know about the DLC/ playing online?
You should be able to find DLC and update files on the internet (you need both), can't remember where I found them. It shouldn't be too hard because they're out for a long time now.
Just had a look about, it seems that Yuzu has the option to download DLC automatically for any games you might have, but Yuzu has been taken down, so would that mean the servers hosting the DLC are also down?
