I'm playing my wbfs games from SD with WiiFlow 4.2.1 and all works great. However, if I start WiiFlow without any usb device connected i got 2 black screens for about 20 seconds. The first comes right after starting wiflow. The second one before the game starts. If I start WiiFlow with an (empty) usb stick connected there is no black screen. Seems there is a timeout it waits for usb device to get ready. Is there any way to skip usb detection?
