seems nintendont is not starting correctly maybe you have a corrupted controller.ini, ninconfig.bin or nintendont boot.dolI've tried both. I've tried injecting them and installing them with WUP on my external, I fire it up, the Wii logo shows up and then the console shuts off. I try running it off of the sd card in vWii, nintendont gets to "Init..." and then the console shuts off. I don't get it.
try deleting any controller.ini you might have on root of sdcard and ninconfig.bin and then redownload nintendont boot.dol.
