Yeah I don’t know about that. A company with that much IP would just sell rights to the highest bidder and stay afloat for ages. If Nintendo sells even just one of their main franchises like Mario, Zelda, Pokémon etc they’re gonna be fine for a long time and someone else is gonna sue the emulator guys all the same.

For example Sega, who went basically belly-up decades ago just sued Memento Mori devs for copyright infringement of in-game mechanics.
