Good luck with that Nintendo... Very much doubt you will win this.
Emulators themselves aren't illegal.
In-fact... Many companies use emulators for commercial and industrial purposes.
For example, some industrial sites I have visited have custom software that interfaces with a plants contactors via DOS to operate equipment, so they use DOSBox on a modern Windows 11 PC to keep that interface going without re-writing the software.
Nintendo has even used Emulators themselves to get games like Super Mario 3D All-Stars running on Switch, Virtual Console, NES and SNES Classic etc'.
And the NES classic in particular, Nintendo leveraged the INES emulator file formats, which shows that Nintendo at the very least- studied the open source work to build their emulator.
And then we have this confuffle...

Sony used the open source PCSX for the Playstation Classic.
Microsoft uses emulation for backwards compat.
The illegal part is the ROMS/ISO dumps.
