Hey all,
I was trying out Yabause Wii and i have a few things to say to those willing to try.
1) When it crashed, i restarted my Wii. It acted like it was bricked (ie, it hang on the "Press A to continue).
But, after a restart it was ok.
2)When i started the HBC later, the wii said "The System Files are corrupt. Please refer to the Wii Operations Manual." Again, after a restart, it was ok.
Bottom line: BE CAREFUL AND USE AT YOUR OWN RISK!
