CLK Rebellion released Xlaunch.fdf Editor:
[QUOTE]
This is a tool intended for devkits, and it allows you to edit your xlaunch.fdf file (which is where all of the images and other files for the dev launcher are held, plus a few extra like the Xbox 360 logo for some reason...).

Quite simple, just load your xlaunch.fdf file from your flash, edit the file you want to edit, and voila.

Don't be an idiot and replace files with a different extension than the one you chose to overwrite it with.

!Update: New version! Had to fix a few bugs.
