How big is the Wii library?

You’ll need roughly 7.53TB (yep, that’s TERABYTES!) of space to be able to emulate every darn Nintendo video game! With the Wii making up 6.56TB of the 7.53TB total, you may want to know the breakdown of the rest of the Nintendo game libraries, so here you go: NES – 237 MB. SNES – 1.7GB.
