Updating has it's downsides, it seems thanks to the update people with import Gamecube games and a freeloader are no longer able to play their import games on the WII after the update.
"Nintendo has remained quiet about whether it will fix compatibility problems with third-party software Freeloader, after yesterday's Wii firmware update rendered it unusable.
It reiterated to Eurogamer that because it isn't an official product approved by Nintendo, there was nothing it could do.
The Datel disc was originally manufactured for the GameCube, and allowed people to import titles from Japan or the US and play them on their PAL console. And up until now it had the same effect on backwards-compatible GC games played on Wii.
Let's hope then that foreign releases will take less time to appear in Europe in future. "
