To all newcomers to Wii Homebrew:
Welcome! We hope you enjoy the wonderful world of homebrew software. Since this post is primarily about the DVD player in particular, and assumes that you are at least familiar with the usage of homebrew software on the Wii, we would appreciate it if you avoid asking general questions like “How do I run this on my Wii?” in the comments – replying to these questions is very hard and clutters up the already long comment list. Instead, you’ll find lots of information at Wiibrew. Short version: You will normally use The Homebrew Channel to boot Wii Homebrew. Modchip users with firmware version under 3.2 can just download the installer ISO and boot it. Users of firmware 3.3 or without a modchip will need a (legit) copy of Twilight Princess and a special hacked savegame that will let you boot the Homebrew Channel installer from your SD card. More detailed guide here. Thanks, and enjoy!
As you all know, I’ve been working on libdi (or the DVD Access library) for a while now. We had some problems getting it out to release because of the difficulties we encountered while writing the second part of this topic. The DVDX installer instead will install a small, hidden, channel on your Wii that allows you to read DVDs on an unmodified system. It is not an installer for a patched IOS. You may however need one, depending on your system.
Usage of this package is fairly simple. Run the installer.dol found in the package, follow the onscreen instructions, and you’re done.
Once you’ve done that, you can enjoy the splendor of mplayer. That what started out as a simple proof of concept has rapidly turned into a full-featured media player, under the nourishing hands of dhewg. The main aim of the mplayer project was to get DVDVideo going, but it also supports reading video files off the SD card. (Experimental).
A patch for Wii64, the N64 emulator for the Wii, will also be available shortly. This patch will allow you to read games off a DVD.
If you have a modchip, you also need patchmii, in addition to the DVDX stub installer.
Note that libdi itself is meant for developers, as it is embedded into applications that use it. libdi requires the DVDX stub. End-users will only need the installer, which can be downloaded separately here.
Please note that DVD+R (as opposed to DVD-R) discs will need to have their BookType set to DVD-ROM to work properly in Normal mode (if you have no modchip). PatchMii mode does not have this requirement, but requires a modchip.
