Coz they're assholes.
sues emulator-devs - but puts old roms onto their own products (mini nintendo etc. contained roms that "pirates" had distributed online for years)
never lowers the prices of their games
sues everyone left and right - like Palworld-developers
They issue takedowns on youtube channels for including nintendo game-music or gameplay
and probably more reasons
indeed. they should sue fitgirl instead, who distributes an emulator, with an included rom and keys etc. ready to play
