Team Cyclops has released firmware version 3.5 for the CycloWiz Mod Chip for Wii. Version 3.5 of the CycloWiz firmware fixes dual layer DVD support. While CycloWiz has always supported dual layer DVDs version 3.0 of the firmware broke that functionality which is now fixed in version 3.5. Installation instructions are available in the support section of their website.
In addition to a new firmware they’ve also released a new tool called the Dual Layer DVD Test Tool that can be used with any Wii Mod Chip to detect it’s dual layer disc compatibility. Since all Wii games are shipped on single layer discs the laser assembly is not tuned properly to read dual layer DVDs even if the firmware supports it. This tool will allow you to test whether or not your Wii is capable of reading Dual Layer DVD discs.
