But we do want that, right? We want people in the future with their unknowable future digital-experience-providing devices to be able to experience the video games of the past/today, right?
So in the interest of making older games future compatible we (those interested in preservation) do need to pursue those things.
How else can we guarantee they'll run on future devices? Emulators are one good way to make things run on newer devices, but emulators will in turn need the features to be able to run on 4K/8K screens, XR devices, etc.
If it runs on a runnable emulator of the target platform then we're good.
