Wii64 problems

I just downloaded the homebrew channel but i cannot get the wii64 application to work. It loads up to the point where it askes me to "chose game", "play game" then it freezes up. Can someone help me?

What version do you have? The one that comes with the hbc?
Try a newer version.

This app is still under heavy development. Problems like that are expected. Also, some ROMs (goldeneye) freeze the emulator.
