Contrary to popular belief Nintendo Wii uses standard DVDs with a modified filesystem for game storage. Nintendo Wii modchip called Viper was released in December of 2006. There is a moded hacked BIOS available for the Viper called Cobra that allows the user to directly boot a back-up or homebrew game on a 3-inch DVD-R inserted in the Nintendo Wii's optical drive . Like most console mod-chips, it attempts to avoid legal complications by including no code which circumvents copy protection or is copyrighted by Nintendo. It has some on-board flash memory which allows the user to write small programs to it (.DOLs). Removing the Nintendo Wii's external case or installing a custom replacement allows the user to boot standard 5-inch DVD-R discs as well, but the positioning of the drive's laser renders only the first 1.4GB of capacity usable. Previously the only common way to run user code on the Nintendo Wii was to use a LAN Adapter combined with a security hole in Phantasy Star Online. More recent (v1.0+) versions of Cobra no longer require an original disc for authentication purposes. TMBinc released an open source IPL replacement for NGC, which allow anyone to produce is own IPL replacement (modchip for NGC). The Cobra software works, after an original disc is authenticated, by resetting the disc drive and unlocking a debug mode which allows code to be sent to the drive and executed. This code stops the disc drive for a few seconds, allowing the user to swap in a non-original disc. Alternatively, the DuoWii and XenoWii are available. They don't have the features of the Viper, but do allow booting of homebrew programs such as SNES and burnt games.

简单翻译：
1,以GC用的Viper直读的基础上专为Wii开发了一块Cobra直读，能够直接读取8cm的D盘。12cm的标准DVD盘只能读取内圈的1.4GB数据。
2,Wii专用的HDD laoder已经有几个了，相关的链接在原网页的最下方。 作者: jason180 时间: 2006-12-3 11:27
