Get a 2nd drive to install it on. Dual booting will only cause you trouble and headaches. For example, if you manage to fix it, next update it will break again.
Note: Bazzite is so established that Marvel Rivals' developer Netease has released game patches targeting that distro specifically. It's the current most recommended gaming diestro.
I use Aurora on my laptop & Bazzite on my desktop.
Thank you for testing it! Are you using Xenia through a launcher (RetroDeck/Emudeck/Retroarch)? Are you on Windows or Linux? any setup recommendations or should I just put the bios files and rom and it's ready to go?
I've seen similar reactions. Is there a particular reason why they are disliked?
