By all accounts on ProtonDB, Halo: The Master Chief Collection works just fine despite being ranked as Unsupported, with the caveat that the game's Easy Anti-Cheat doesn't work on Deck/Linux and therefore online multiplayer doesn't work. I'm not interested in the PvP anyway, but I do enjoy playing co-op through the campaigns. I haven't had a chance to test if co-op still works, whether online or via LAN, but I'm not sure why you'd need EAC for co-op in the first place. So I don't really have my hopes up but I'll keep my fingers crossed that co-op still works.

Thanks for this! I'd wanted to get it, but passed when I saw unsupported. I know on Destiny 2 they're making it so that if you even try online play, your account gets banned.
And even better: I didn't think I was interested in setting up an SMB share but after seeing the image and skimming the instructions, I'm starting to see the potential appeal. I can see it being especially useful for having a large ROM/emulation library accessible on demand without having to take up space on the device itself.

Yeah, I was thinking about it because even with 512 GB additional, I'm down on space, and I thought about just setting up a share for those things I want to play at times, but I didnt want to switch out SD cards like I see some doing.
