The latest Wii system update in Japan added a new, shiny button to the Wii Shop Channel. Just below the buttons linking to Club Nintendo’s website and linking to the user’s Wii Gift settings, a new “Bonus Content” button sits patiently. Upon clicking, you’re required to enter a 16-digit code to obtain some kind of bonus content. What is it?
Well, right now, the one code out there nets you the Speaker Channel, meant to interact with Band Brothers DX for the Nintendo DS. Not much, but things get oh, so exciting when you consider the types of bonus offering opportunities this opens up for Nintendo and other game publishers.
