I never said it comes up in vwii try reading what i said properly... the simple solution is to make a "usr" folder on the usb and copy all of your loadiine and homebrew files over, it will remove the popup nag and everything will be read from the same usb drive after mocha has loaded.
Sorry my main language is the french. Yes i have make a folder usr , mocha have removed the pop up. It has a way to remove this pop up also on the original sysnand? Because I have not installed coolboot i have only haxchi.
I have testing some games on the HDD with Loadiine and is work. But like smash bros, mario kart 8 .. is not ever start with loadiine I waited until 10 minutes and still nothing..
