They made freeloaders for the wii that also gose with the game cube but the cd is the size of the wii games. and yeah i use the freeloader. here's some videos.
Many thanks for the info about the new Freeloaders, that's the first i've heard of it and very welcome news that they can enable playing old region locked Gamecube games!
The videos look good, but it looks like rather a simple hack'n'slash with the Wiimote (with rather PS2-quality graphics.) Is there more to it than that? Am I missing something?
