While playing some Wii games on my Wii U (vWii; through USB Loader GX2) it sometimes happens that a game freezes. When this happens, nothing short of removing the power plug works. I don't want to reboot my Wii U like that, especially not when my external HDD remains very active as it could seriously damage the HDD. The notion of every game freeze putting my HDD at risk doesn't sit well with me. Does anyone know a way to reboot after a game freeze that does't put my HDD at risk?
