PSP Depackager (A tool to decrypt .pkg files on PSP) is released by qwikrazor87

Developer qwikrazor87 released a tool which makes decrypting the official psn pkg files on PSP possible. PSP Depackager can decrypt PSP/PS1 pkg files (no PS3 files). There are PC tools for that, but having a .pkg decrypter on PSP is great.

As the decrypted files will still need a license, they won’t directly work on OFW. You have to use CFW and npdrm_free plugin for that. For PS1 files, PSP Depackager v2 extracts KEYS.BIN file too, so you can boot it via your CFW.

Here is the readme:

This is a homebrew to install PSN PSP pkgs on the PSP.
pkgs should be placed at ms0:/pkg/, if that folder does not exist, then create it.

place included homebrew on your PSP.
ms0:/PSP/GAME/PSP depackager/EBOOT.PBP

This homebrew only supports installing PSP retail pkgs and files, PS3/debug pkgs are not supported.

boring info, uses the MagicGate hardware for the AES crypto,
no idea about any benefits/disadvantages with it compared to the kirk engine.

Thanks to @ReRepRep for the idea.

Changelog:
v2:
Added KEYS.BIN extraction for PS1 pkgs.
v1:
Initial release

From my test on a 6.60 PSP GO, it decrypted a 210 MB PS1 pkg in 7 minutes, extracted the KEYS.BIN and i could boot into the game without a problem. Thanks to qwikrazor87 for this great homebrew, hope to see more.
