So I'm trying trying I help a friend setting up a cfw. Browserhax already works fine. The problem would be the gateway menu now. Apparently you need to have cubic ninja or Zelda oot for that. Luckily we both have oot and I have a 2ds with cfw. So I booted up gw menu with the browser and imported the save and extracted it for him using svdt. He then imported it and tried to load the menu. Everything shows up, but when he presses A only that white screen is being showed at the bottom screen....
