The downside is the community's documentation is scattered trash compared to any other technical part of the internet.
It took me almost 10 years to finally enjoy Ocarina of Time that I have a legit VC copy of. I want to load up a majoras mask wad and all the forum posts just read like lists of codewords i'm not cool enough to know. I set this up almost a year ago, I don't remember what ios versions I installed. I'm gonna have to reboot this thing like 10 times before I figure it out.
Edit: Hacked my 3ds for advance wars, holy shit themes have sound.
Sure, but I'd either be sitting at my desk or have to carry around a controller and a place to put my phone, or use a precarious clip.
I use an old laptop connected to a tv to stream media so for older games, I'm sure it could work. I guess it all comes down to if I'm not comfortable playing the game then I wont end up playing it. Some games make sense at desk, some make sense on a couch, some should be mobile. Disco Elysium is no fun on a couch, trust me I've tried.
