Crazy Intro is an autoboot homebrew to use along with Preloader.

You can use Crazy Intro to customize the opening of your wii. You can display your selected picture and play the music of your choice at each start of your wii. Also you can assign your frequently used channels/programs to any button on your wiimote. You can use B or your configured button to quickly access homebrew channel.

Changes:

Compiled with latest Grrlib 4.1.0 / devkitpro r19
Default intro can launch the Homebrew Channel with the new title id.
Added random theme support, in CrazyIntro.xml config file set the theme as random. The example configuration in the distribution also uses random.
Added random/sequential (up to 9999 pictues) boot picture support. So in a theme you can have multiple boot pictures and program will alternate between those boot pictures. See theme_explained.xml or supplied kanji_10 theme for it’s usage.
Improved dol/elf loader, still buggy though in certain apps.
