[Release] psardumper mod to extract 3.00 (NOT decrypt)
Extract 3.00 (encrypted only, need new keys)
Press CIRCLE, the other options don't work. If you try SQUARE ("decrypt all") it extracts the data files which aren't encryped and skips the PRXs
3.00 DATA.PSAR goes into root of memory stick, use PBP Extractor to get it.
(Can read PSAR files up to 18mb [3.00 PSAR is 16.7mb])
Cheers to Dark_AleX for psardumpermod, and zshadow for the buffer fix ;)
Stuff to note about the firmware:
- No more ./vsh/resource/1.bmp, 2.bmp, 3.bmp (etc.)
Instead, there's now just a 1-12.bmp which is grey. The firmware probably applies a colour overlay onto this.
- audiocodec_260.prx and mpegbase_260.prx
Audio/video codecs from 2.60..?
- Just 1 certificate in "./data/cert" folder
Discuss anything else you find.
Probably a worthless post, but..
So there are so many guys out there who really know what they are doing, and I am facinated by this. I would love to help, but I also would just like to learn how anyone is able to even *begin* to make headway on this. To find the key for stuff like this seems like it would take FOREVER, but what can we do to help, and is there somewhere I could look to learn more about this(i.e. the process' people used to decrypt the previous firmwares, etc.). Anyway, I continue to be astounded by the things you guys are able to accomplish out there. I hope you're all making big bucks in your real jobs.
I only Know a little about the way firmware work via some research and expiramentatio
n... But Technicially if you can extract and decrpt the prx's in which allow for version support, and booting of 3.0 games, couldnt you make a custom firmware that boots esscentially 2.71 and 3.0 game support?
Just a thought.
