The update, however, was optional, so Freeloader owners who spotted the news online simply had to avoid updating their consoles to carry own playing their region-free games.
Nintendo isn't that stupid though! It has now confirmed that every game released after the 3.3 update will only work if you updated your Wii.
So, the choice is yours. 'Freeloaders' can either continue to play only the games that they've bought from other regions for the rest of their Wii-owning lives,or choose to update and be play only region-specific code.
Not much of a choice is there really?
