It looks more like they're just hoarding a massive personal collection of games... No mention of if this is open to public.

Or if they're even digitizing the games for some use of preservation. I always feel like when you hoard things in one location like this, one fire or other natural disaster and the entire collection is gone!

They would be violating Swedish copyright law if they did, so they better not!

Much easier to get away with such things in the US (it seems).

You don't need a physical archive to do that; a torrent of a bunch of SNES games would be good enough.

Pretty much every game ever published has been digitally preserved already. I don't think you're going to get much out of feeding a binary into a pretraining dataset though.
