you can always play them on emulators :) it is quite dark indeed.
Keep in mind that emulators fix graphics a lot.
lol I just realized that I was playing wind waker on an emulator for fun (its my favourite game btw) but when I moved my computer to the new house I stopped playing it for some reason. I'll definitely get them on my emulator, along with some other game cube games I haven't played in a while.
by dark i meant disturbing btw.
