I recently got WiiFlow and got mariokart and NSMBWii on it and they work fine. But then I downloaded World at War and when I start it the screen goes black and the system resets. Im kind of a noob, but not completely. I'm just really good at following tutorials, so if you need any additional information please ask me to provide it. I would really like to know how to fix this and am very thankful to anyone that helps!
