== How it works ==
BootMii is a modified version of [[boot2]], which is loaded by [[boot1]], which is loaded by [[boot0]]. '''boot0''' is part of [[Hollywood]] and read-only. '''boot1''', although stored on the [[NAND]], is signed by a value in write-once memory and therefore cannot be changed without rendering a console unable to boot. '''boot2''', however, can be modified (with some restrictions). This means it can be hacked, updated, and corrupted. BootMii hijacks the boot process before the normal '''boot2''' is run, optionally allowing code to be run directly from the SD Card. This has many advantages, such as making it very difficult to [[brick]], and slowing Nintendo from blocking homebrew. Unfortunately, the only way we could completely stop Nintendo from blocking homebrew is by patching updates on-the-fly, or somehow preventing overwriting '''boot2'''. Along with the [[System Menu 4.2]] update, Nintendo released a new version of '''boot2''' (boot2v4); there is nothing in boot2v4 that prevents BootMii from working, but it will overwrite an existing BootMii installation when it is installed.
