I got an import copy of Baten Kaitos origins for my Pal Wii, but no matter if I use Neogamma, GC Loader or Gecko OS, after some playtime I get a "Disc could not be read" error that seems widespread with BKO. Was there ever a fix for this?
If its a widespread problem, you may not be able to get it working I'm afraid. :( One thing you could try (although I'm not really sure I advise it) is try this product: [uk.codejunkies.com] - I say I'm not sure I recommend it as it is a paid solution and may still not work. But it may be worth a shot.
For anyone looking for a solution: It DOES seem to work with GC Loader now. My last resort would have been playing it on a original Cube with the Freeloader.
