I am using Waninkoko's wii dvd dumper v1.2 (custom IOS249), and i have no problem dumping gamecube disc (GOD). However, when I try to dump any Wii dvd disc through Wifi, i get and error message at the final phase which is the one where you need to connect your computer and Wii to download the .iso file. The error I get is: >>Sending index.html... OK! >>Sending DVD ISO... ERROR! (ret = -10056) OK! I'd also like to know how to make the differences between a Wii single-layer Disc (WOD) and a Wii dual-layer Disc (WOD DUD9)?
