More for the rest of us, I guess.

Sure, if they subscribed to literally everything and had started doing so right from the beginning.

Not holistically, as an archive. When new content is posted on an instance it gets pushed out to any other instances that are subscribed to it. That's the only time the content is sent out. So if you start up a new instance but don't subscribe to anything nothing will be sent to you, and you won't get any historical content sent to you from beforehand. The Fediverse isn't a "flood fill" mesh.

I'm not aware of any similar public archives of Fediverse content.

I just spent a bunch of time talking about PC emulators, why would I just keep repeating myself?

I just checked, that game came out in 2001 so I assume it runs on Windows 98. You can install that on DOSBox.

The PS1 hardware isn't being made any more, it's not going to last forever either. PS1 emulators will be needed for that as well.

perfectly tuned for it.. for how long though?

Perfectly tuned forever, just keep the game bundled with the same emulator.

If eventually the system that the emulator runs on diverges too far from what the emulator was able to run on, then wrap it in another emulator to emulate that. Or just update the emulator, DOSBox is under the GPL.

How many indie titles on PC aged out of the platform and have no maintainer?

If you have an emulator then you don't need a maintainer. As far as the game is concerned it's still running on the exact same computer that it did when it was first released.

A person who purchased Harry Potter and the Sorcerer's Stone for PC would be unable to launch the game in any modern OS. But if they have it on PS1, it still works.

They'd need a PS1 emulator for that. DuckStation, for example.

A person who purchased Minecraft in 2011 can no longer play that game on the same computer they purchased it from.

The newer versions of Minecraft can't. The old version they purchased in 2011 still can because it hasn't changed.

I'm saying PC is a moving platform.

And I'm pointing out that an emulator need not be a moving platform. It can be a frozen snapshot of a particular moment in time. Get a game working on an emulator and you can freeze that emulator's code and configuration and then you'll know that the game will always work on it from then onward. Bundle the emulator with the game, like GOG does, and there's no "fiddling around" - you can indeed just sit down and play it.

You can swap out their dosbox.exe with a version that includes CRT shaders, such as DOSBox Staging or DOSBox-X.

Or you could wrap the existing DOSBox window in an external shader using ReShade, it's a universal post-processing injector that can add a CRT filter. That way the emulator they wrap the game in remains untouched, you're just modifying the visual output.

My search also found all-in-one frontends called ExoDOS and LaunchBox/RetroArch to do this to a whole library of GOG games so that you don't have to do it individually to each.

The answer there is emulation. Good Old Games sells old DOS games and they work fine on modern computers because each comes wrapped in a DOS emulator tuned perfectly for it..

I literally never give my phone to anyone else physically. And if I had it set up with a self-destruct button like this I would be even more fastidious about making sure it's backed up than I already am.

Why do you know what the inside of a drawer in a jewelry box you found in your deceased grandmother's closet tastes like?

For example, would it be considered destruction of evidence if a defendant had written it on the back of the phone and the officers assumed it was the correct PIN? That’s just a hypothetical

What a good idea! Hypothetically. :)

Finally Russian air defenses manage to shoot something down.
