This is basically a generic flasher which can flash whatever files your heart desires. You can flash anything from individual files neatly organized as you wish, all the way up to entire themes also organized as you wish. You can also save precious flash space for themes with the click of a button – backing up your files as well. The customizations available to your PSP are endless.
