Hi, I am wondering if I can install any distro or does it need to be made to support the PS4? I was thinking ChimeraOS would be great on the PS4. It supports Steam, GOG and Epic games, as well as emulators. Basically it is a souped up SteamOS with a very up-to-date version of Proton. This is pretty big as recent Proton updates brought OFFICIAL support for Battle-eye and Easy Anti-Cheat (what Fortnite uses), though not yet perfected, it still means online gameplay on the PS4 is viable. Lastly and most cooly, Chimera uses a web interface that you access from your browser entering the ChimeraOS device's local IP, then signing in and allowing you to import your PC Games library/emulators/ROMs etc.
No, I don't work on this OS, I am not a 'nux fanboy either, I have done some research on the most noob friendly gaming oriented 'nux distro and found this, which is a successor of GamerOS which is a branch of SteamOS and I really would LOVE to see this on the PS4. PLUS+ with the SteamDeck on the horizon and SteamOS being open-sourced, the improvements of SteamOS will carry over to other branches, like this...when updated that is.
