A method has been found for dumping Wii game discs via PC. Unfortunately, the process takes approximately 50 hours to dump an entire disc!

A readme with instruction is included. Remember, this process takes over two full days to dump a single disc. This method is suitable for testing purposes only!!!

Update: I’ve included both the old and new versions of the app, per request.

I have been reading a lot of posts on other forums (who don’t credit us as the source, by the way) from people claiming this is working with other drives, reading the whole disc in just a few hours, etc. The program uses debug commands in the LG (Hitachi) firmware so that is pretty much impossible. You may be dumping something… but it’s not the correct data.

You will need: An LG-8164b, LG-8163b or LG-8162b DVD-ROM drive.
The DVDInfo program.
.NET framework 2.0 installed on your PC.
