Wii Menu
Wii softmodding is also closely related to the methods used to softmod Xboxes and PSPs. The first known method of loading unsigned code on a Wii (without a hardware mod) is known as the Twilight hack. This allowed users to run unsigned .dol/.elf files. The exploit was superseded by the development of Bannerbomb, which allows a user to run unsigned code on the console without relying on an exploit within a game. Bannerbomb works by using a malformed banner to inject a loader program into the Wii Menu program in memory. As the Wii Menu crashes, an unsigned executable is executed. Bannerbomb was superseded by Letterbomb, which uses a glitch in the Wii Message Board to crash the Wii Menu and load the .dol/elf file, allowing the user to install the Homebrew Channel.
