Yes. SSBB contains the "dual layer" implementation of the (001) protection that was first implemented in mario galaxy. D2CKey was never tested against the dual layer version and apparently they got it wrong. Other chips have similar problems.

There are workarounds (i.e. manually setting the layer break or removing the protection from the ISO).

more details can be found here:

So will it work if you set the layer break to the certain point(s)
