Hey i have a Japanese wii i currently received as a present from relatives and i dont know if it has any sort of adjustments added to it, like a wiikey. I recieved some back up NTSC(U) games with it, and it works fine on the japanese wii. But when i try to use to wiibrickblocker on it the iso the game wont work anymore. it loads but i just get a black screen. so my question is, is there any way of telling if there is wiikey installed already? and should i just keep the games without having it wii brick blocked?
