I always wonder who the folks who build these things are. If they become too popular, it seems like a good way to have the government pay you a visit you will not enjoy. But they also seem like technically interesting problems to solve. Glad someone is out there preserving these games in any case.
This one is made by Russians. Their government has bigger problems to deal with. They turn a blind eye as long as Russian companies are not targeted.
This generation's "geohot" and friends, most likely. Curiosity, youth and a much lower entry barrier will always win.
A lot of people live in places where the government does not really care to use police to enforce copyright, or where this just isn’t really considered illegal.
The PlayStation platform in general is the easiest console to reverse engineer. There’s a lack of security in depth that makes it easy to reverse engineer.
It’s only recently (earlier this year) that the _last gen_ of xbox was cracked.
They might be technically interesting problems to solve but these days they're just using AI to solve them so they aren't really learning anything about those interesting problems.
