has anybody else noticed, that the game case (for a specific reason) is coloured red?
Remember the Shiny Zigzagoon event in the US where the zigzagoons had a patch to cure the berry glitch? Well, when youy first put the cd in your wii, it asks you to have an upgrade. I believe this upgrade not only ads a new feature to your wii but also fixes several bugs.
Almost all Nintendo games do this, it's how they counter piracy on wii's that don't connect to the internet. It has no relation to the box colour.
