I've got a modded wii, 3.1, trying to boot no more heroes US, it appears in the menu with all the fancy animation etc, but when you press start it gives a "error, game disc couldn't be read. Read wii operations manual". Disc burnt at 4x, so there shouldn't be any problem with it, other games work fine. My friend had the same problem and he solved it by booting via gecko regionfree loader. However, I get the exactly same error.
