 |
|
Hi. I'm a newbie in PSP development/programming.
I'm interested in learning on how EBOOT.BINs are decrypted, or how PRXDecrypter (by jas0nuk) does its decryption routines. I'm looking into decrypting newer 5.55 EBOOTs.
Can anyone help? Was PRXDecrypter's source code (preferrably for 2.0) ever released?
I would think that PRXDecrypter would require either the decryption key programmed into it, or would require a new decryption module installed into the firmware (mesg_led, I think). |

It's against the rule here to help you with game related hacking.
But as far as the general decryption is concerned, you are right, non-kernel modules are decrypted by msg_led.
I have never found any source code for prxdecrypyer either, although many people might expect that it's open source. You can alternatively lookup psardumper's source code though. I think they are similar somewhat. In your case, msg_led already has the function you are looking for anyway. If current decrypting programs don't work anymore, you should expect they would at least change the decryption key.

Sorry about that, then.
In any case, I'll look into PSARDumper.
It's probably the decryption key that's missing, then. |
