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
This is very educational, thank you. Just out of curiosity, what has Nintendo done with the 64dd? I thought they had forgotten about it
