application is about Wii software packaging. For the data files used by Doom, see [[WiiDoom]].''
The WAD file-format is a file-format that contains information for the
wii, such as System Menus, IOSs, and Channels.
Unfortunately, WAD files are often used to distribute pirated channels (both Virtual Console and WiiWare), due to the fact that they are also used by Nintendo and therefore easy to rip from the Wii and, for some WAD files, Nintendo's servers, and easy to create installers for. Wiibrew does not in any way endorse piracy, and as such these uses of WAD files should not be discussed.
== System Menu ==
WAD files are often installed in the Wii System Menu to appear as channels, making launching easier. If a WiiBrew app isn't installed as a channel, it can usually only be launched from the Homebrew Channel itself. WAD file creation seems to be an intricate process and tools are difficult to locate, and most are based on the .NET framework. Associated with WAD file generation are forwarders, which when loaded simply load another
arbitary application. A common technique is to use a somewhat generalized WAD that can be easily customized to then forward to another WiiBrew application stored on the SD card.
Wii System Channel WAD files exist for WiiMC, ftpii
, The HomeBrew Channel itself, and numerous others.
Forwarders are somewhat easier to locate, a common one being the Narolez-NForwarder, for which source exists and is easily modifiable. One WAD generation system that still appears to be active is the CRAP system that appears to be .NET based. The Wadder system also seemed to be .NET based but it appears abandoned. Although these tools are often associated with piracy, there are clearly legitimate uses for them as well.
