Some new loader images i made
get the tga here:
Others care to share theres?
download and extract the rar, rename the one you wish to use loadmenu, then move the file to <pspdrive>/psp/game. then you have your new background, it will ask if you want to overwrite an old file if it has worked correctly:)
[EDIT (Fanjita): The bulk of the images in this thread have been kindly collected on this website by flare576.]
