I don’t see why it would be hard to accept that someone could make a carbon iron alloy using carbon and iron. But in any case in this link there are multiple sources, an archeology book and a scientific paper, of these claims https://bigthink.com/hard-science/norse-rituals/
FTFY. The problem is not with Nintendo being against emulators because of piracy, they’re against emulators even if you own the game and the hardware but want to preserve the hardware (just like they do in the museum).
And if the counter-argument is that you don’t own the game when you buy it, then by that same logic you don’t steal it when you pirate it.
