yes it is. what they’re doing is shitty, not illegal.
"Hey don’t use emulators to play our games we’re gonna sue you.
… and then just take that emulator software you made and sell it in our official devices. but still fuck you."
not illegal. just giant assholes with no sense of self-awareness.
They’ve never sued anyone for playing an emulated game. They have (most likely wrongly) threatened emulator developers over circumventing copyright and encryption. I don’t like it anymore than anybody else, but are we actually mad at a company for preserving their games? You can hate them for what they are doing to others while still being ok with their own emulation
