Korean Gamecube support.

I know the Korean wii dosent play GC games but lets JUST say I was going to install the mIOS would it play gamecube games?

And BC.

I'm not quite sure, actually. I don't think it would.

Maybe if you changed the region to USA or PAL. I dunno. But if you do that, make sure you do not install System Menu 4.2, it would brick you. And its kinda risky anyway. I dunno if it'd work.

To sum it up: it might, but don't try.
