So can i play it using a NES emluator on a hacked wii

I’d just use Wii VC but check in the discord to make sure it’s legal.

Usually it is fine. Sometimes emulator accuracy is sacrificed in favor of performance, especially on old consoles, so we need to know the specific emulator used.

What is the nes emulator? Name and version?

I believe the only NES Emu on Wii is FCEUX
