Ok, since nobody got anywhere with this on GBATemp I'll post it here. Basically, I changed my region, downloaded the Kirby TV Channel from the European Wii Shop, and put it on my menu. Whenever I try to open it, I get blackscreened.
Somebody said that it needed an up to date version of IOS56, but updating that did no good for myself, or the person he was attempting to help. My attempt to bump the topic fell on deaf ears.
