Today, a foreigner has released a program for backing up dual-layer discs, but it is estimated that due to legal reasons, including himself, it's only for testing and the Brawl ISO has not been released. We look forward to this software becoming more and more public, and there will be someone brave enough to release the ISO! Below is the news: Nekokabu has released the first 'dumping' program to back up dual-layer discs on the Wii. This program works on a compatible DVD-ROM and can generate an ISO. The source code is also in the download package, it's a command-line program. Update: We noticed that today this program is only for dual-layer disc backup, and for some reason, the program author does not intend to test the copy function. He suggests that other people test and burn copies. In addition, someone successfully copied some dual-layer discs, but said that Wiitools cannot decompress the content of the disc, we estimate that Wiitools cannot operate on dual-layer discs. Update 2: The author of Wiitools clarified that he has already tested the dual-layer disc ISO with this software, and Wiitools can decompress it. So yesterday's update was a wrong message from a player. Software download address:
