I just recently got a wii. At first I would download several games in ISO format. I would burn to dvd, and I have no problems. Burned about 15 games this way and all work. Afterwards I used the Wii Backup Manager and converted to WBFS to make the file size smaller and got rid of the ISO. Lately I have downloaded more games and converted to WBFS format right away before burning (Imgburn). Then later i would use Wii backup manager to convert back to ISO and then I have burned 3 games so far and I get this same error. Games: Bolt, Fantasy Aquarium World, and Kawasaki Quad Bikes. I used this guide a couple weeks ago to mod my wii. http://gbatemp.net/t171901-modify-any-wii-4-3-below It looks like neogamma is trying to load it but is just halts and shows "Disc Err(1938)". I convert to WBFS because of the small file size of some games and also because I intend on using a usb hard drive later down the road. Question: Going from ISO to WBFS to ISO, then burning causing my problem??? Question: If so, do I have to redownload the games or anyway around it? Am I doing something wrong" I wanted to ask before I waste anymore dvd-r. Update: I have tried another game...Mario kart and it works converting from WBFS to ISO then burning. I looked up Err 1938 and I can find a single reference to it on the internet.
