For PSP developers at least, the excitement keeps on coming with this release from Jas0nuk from our forums that allows you to extract PSP system software v3.00 firmware files. This Psardumper modification allows you to extract (not decrypt) files from 3.00. Just place the 3.00 DATA.PSAR into the root of your memory stick, and use PBP Extractor to get it (Can read PSAR files up to 18mb, 3.00 PSAR is 16.7mb).
We will state again, this Psardumper modification does not decrypt the encrypted firmware 3.00 files (instead it skips them), and therefore will not allow you to emulate it using DevHook or something like it.
However, what it does allow developers to do is take a sneak peak into firmware 3.00 and learn more about how it works. Here's a few things that Jas0nuk has found out about firmware 3.00 by using this mod:
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
This application proves that although firmware 3.00 is quite solid in security terms, it isn't uncrackable! Jas0nuk would like to say thanks to Dark_AleX for Psardumper mod, and zshadow for the buffer fix. Remember to report any findings you have using this to the psardumper 3.00 mod release thread!
