Hacking what does exactly Preloader do?

[kisamesama]

are you brickproofed when u install preloader like starfall?

does preloader works on 3.3U?

haven't seen any detailed description in its readme or on wiibrew.org

you are never gonna be brick proof with either preloader or starfall but your chances greatly increase with them

As stated above, brickproof is not guaranteed, but preloader reduces the risk. It means that even if the main system files are screwed, there is something that can be loaded before the messed up system menu. This allows for repairs of most problems. Definitely recommended.
