Homebrew developer jas0nuk has released an updated build of PRXDecrypter, a psardumper mod to decrypt PRX modules and firmware resources. The author let us know that the program is currently incompatible with 3.60 M33, but support is planned for a future release.

Changelog:

1.5b –> 1.6
- Now comes with a HEN compatible EBOOT which doesn’t seem to work properly (partially broken on 3.xx kernel on the fat PSP,
` completely broken on 3.60 M33 due to new hardware)
- Added 6 more key sets (1.XX, 2.00-2.50, 2.60-2.71, 2.80, 3.00 and 3.10+ gameshare keys)
- Now press TRIANGLE rather than HOME to exit
- Fixed 2.7X demo decryption (wrong key)
- Removed 5 useless keys
- Now uses the entire buffer – previously, files over 4mb would fail
- Added second layer of descrambling to a few files – this would have produced messed up output if you tried in the old version
- Waiting for the 3.60 and 3.70 keys… I’ll add them as soon as I have them.
