Suppose I’m playing an 80’s RPG on real legal hardware and I’m tired of grinding for XP. I use a cart reader to dump the save file, write a save file I downloaded from the web and finish the game. I don’t even have to access any copyrighted data to do this!

Unless you think data that amounts to

{
  "rtc": 1713006754,
  "savestates": [
    {
      "name": " Red",
      "xp": 1760,
      "pokemon": [
          {
            "species": 115,
            "name": "Fluff",
            "hp": 24
          },
          {
            "species": 92,
            "name": "Bonk",
            "hp": 11
           }
        ]
     }
  ]
}
