Now there is a 68k JIT for PPC the Wii should be fine for Amiga emulation once it gets ported from the OS4/MorphOS version.
Actually, UAE on the Wii isn't bad. It just got another update a few days ago in fact.
JIT would not hurt, but it certainly won't bring much new to the table. With the system's RAM limitation, we still won't be able to do much more than play games with it.
I'd just like to see a nice polished pachage released, or some VC channels. Would be AMAZING to be able to fire up Myth on a VC and rather than have to remove a hand from my controller and reach out and press the stupid space bar to change weapons...
...I could just press Button 2.
EDIT: On that note, are Euro game devs on crack or what? They had acess to more than one button and they ignored it, thinking that removing a hand from a controller and reaching towards the keyboard would be more practicle. Crazy!!!!
