What does it mean when a system report of your IOS's says that certain IOS's are stub or trucha bug?
A stub is a useless IOS. It is nothing more that a "place holder." The main reason Nintendo installs stubs are to overwrite cIOS's. The other is to fill the slot of an IOS that is obsolete (aka "mothballed").
