Yep, it's like one day we expect an old game to work in VR++ and my 950pi smellovision implant.
If it runs on a runnable emulator of the target platform then we're good.
If it runs on a runnable emulator of the target platform then we're good.
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.
