Freeloader is useful even with a modchip because as of right now, all modchips have about 80% compatibility. Jap Wii's even with modchips can't play american SMG so they either have to trucha sign which is a pain in the ass, or simply get the japanese freeloader.
Don't ask why someone would have a japanese wii when they speak english. Just don't.
As for americans, we can now play that naruto game which no mod chip has the ability to play as of yet!
And Pal gets everything, they can support SUDA51, buy no more heroes american, and play it on their wii with full gore. Hooray.
