I live in the UK with a PAL Wii and imported a copy of ssbb just a bit after its US release. My wii was unmodded @ the time, and I played it using freeloader (I ran the update on the disc).
Anyway now my Wii is modded with a Wiikey modchip with the 1.9s fw. I thought that I'd be able to play ssbb now without freeloader / gecko region free, but as I put the disc in it comes up wii system update. But I've already done the update and don't wanna BRICK my wii. Oddly I'd blocked all updates from games with the config disc. Yet it still comes up wii system update.
