Вот типа инструкции от hrimfaxi

Сообщение от hrimfaxi Source: http://bbs.a9vg.com/read.php?tid=1486475 It's a completely rewritten prx decryptor based on 6.20 mesg_led_02g.prx. Right now there is only a POC version, but it already can decrypt 0x2e5e10f0, the key tag which pspdecrypt.prx failed to handle with. It also means you can decrypt PBOOT.PBP (game patch) since many patches use 0x2e5e10f0 to encrypt themselves. Usage: Use unpack-pbp to unpack a PBOOT.BIN. Rename DATA.PBP to EBOOT.BIN and move to ms0:/enc/. Run PSPCipher, the EBOOT.BIN will be decrypted. Replace original ISO with new EBOOT.BIN and PARAM.SFO. If you use Prometheus module then EBOOT.OLD instead. Right now, God Eater 1.01 patch and Idol Master SP patch are tested.
