There was Bleem! (https://en.m.wikipedia.org/wiki/Bleem!) Which was a commercial PlayStation emulator that won a case against Sony, but ended up going backrupt from the court cost (according to Wikipedia).

I would start by trying to scan the site using something like nmap or Metasploit (https://www.metasploit.com/) to see if they find anything.

http://crackmes.one/ is new and updated. It also includes all the old crackmes.de challenges.
