hey guys you know recently we can download psp games via pc from psn but it comes non eboot.pbp format. it comes xpd formatted small sized file when we open that xpd file with psn downloader downloadin a pkg file extracting that put in psp as a pbp format this is strange so that psn downloader can decrypt pkg files when we opened xpd file with notepad we got some information like that.
i think that file contains decryption information may be we can find a way decrypting psp succesfully. one thing more you can install that pkg to ps3 succesfully but when you attempt to play game ps3 will tray put that in psp.
