Ive followed the photoshop tut, but now al i get when i boot the PSP is no text at all. Ive also been reading the forum up a lot and the request page is there but I would like to know the trick to custom coldboot. I know im close. But obviously im not close enough. thanks. Even a link to a solid tut would be appreciated by all means.
