PS4 games running on PS5 are a thing because Sony literally made a "mock PS4" with their BC mode. Xbox One games on Xbox Series are a thing because of the very design of Xbox One games: they're literally contained within virtual machines. That's why they can be released untouched on any future Xbox console and be played by just downloading a VM profile.
Both console licenses were for games under a VERY specific platform and under VERY specific conditions. That's why emulation is still illegal in most platforms.
Nope.
The entire argument in this thread is game preservation and all the legal bullshit that's impeding it. Support for older games and software ended years ago and we all acknowledge that. We're talking about LEGALLY having the ability to run software on a platform that they weren't designed for, not if they're supported or not.
Are you THAT dense?
And yes, as Phil said, we need this to be an industry-wide thing for it to work, otherwise it would be relegated to PC (since it's an "open" platform) with VERY dubious legal status.
