Resetting only returns you to your save point, which usually isn't too far back in time.

If Sans wanted to purge Gaster of Giygas' infestation, he would have to warp YEARS into the past, back into the world of Earthbound, and prevent Andonuts from ever making a pact with Giygas. Something that happened long before Jeff, and Ness, were born.

The Silver Key Machine might have been able to track that trip. But Sans can't do it under his own resetting power. Especially not after being trapped in the Underground by the Barrier.

Gaster may have been forgotten, but several monsters, certain Toriel, knew that the bizarre tech used by The Core didn't come from the surface humans.

They don't remember who Gaster was, but the know -someone- was there, and did something to help them. Sort of a "Warrior of Light" that everyone knows of, but nobody can remember clearly.

Again, we do not know that the mosnters consider "modern'. Undyne could easily have been saying 'we get modern technology from the garbage dump' to contract it to the alien technology in the Core.

Napstablook loves his dated audio equipment and chiptunes. Toriel has an old VCR camcorder. The Libarby is still full.. of actual books. Monster society has fully embraced the human 20th century.

So the alien tech still sticks out like a core thumb.

Scientific revolutions take time, even for a man like Gaster. Just getting ot the Underground with the Silver Key Machine itself was an amazing feat.

But if you drop a mad scientist in the middle of a society using 20th century human tech, he'll already know decades of advances which he can implement immediately, wowing everyone.

Do you really think something mundane could end centuries of perhaps-irrational monster fear of the massively overpowered surface humans?

The Migration to New Home wasn't a gradual thing.. it happened fast, somewhere between the start of 201X and its end. A civilzation that's been living in fear for hundreds of years doesn't just one day say "eh, screw it" and completely forget the horries of the earlier war.

Something happened that made the monsters no longer fear humans. Something big.

Gaster's alien tech would certainly do the trick. And he must have been on hand to supervise construction of the Core.

Undertale didn't originally have a donation box. It suddenly appeared as an update.. after Detlarune came out, and mentioned that their donation box has fallen through a hole. And suddenly appeared in Undertale's garbage.

So yes, they are the same box. This was a super deliberate detail.

The Dark World is another incarnation of The Underground. Complete with Asriel, who's still down there.
