The preloader adds a screen to the systemmenu that comes before the health screen that allows you to boot the HBC, an installed DOL, or the systemenu.

 

It doesn't change the healthscreen...

 

I belive it is supposed to be able to load DOL files when you start up the wii. You can get a dol that patches the wii To run backups from the disk channel but this feature is not working with most homebrew files.

 

it allows easier and more reliable banner brick protection than the starfall + TP + diagnostic check Combo I have in my sig.

 

hmm...yea it adds those but you got to insert money in the disc slot for that function
