    Question

    Will this enable 6.20 CFW updates?

    According to the second screenshot the author said Thanks for the 6.00 - 6.20 keys so I imagine at least some 6.20 games that work with GEN CFW will now work with M33 if that is what you are asking.

    If anyone gives it a try (no PSP here) and can let us know for sure I will +Rep ya of course!

    Also, attached below is the EDecrypt Source Code, some patches and a PSP Compatibility List for this from the Russian group that mc707 belongs to at: revenge-crew.com

    Below is also another homebrew app called EBOOT Exchange by takka that decrypts the Eboot.bin directly in the iSO (without having to extract and rebuild).

    A new EDecrypt version 1.3.2 is now available, so I attached it below. Here is the changelog:
    EDecrypt v1.3.2
    ===============

    Based on PSARDumper's sources.
    Recompiled and optimized by mc707.

    How to use
    ==========
    1. Copy EDecrypt folder to ms0:/PSP/GAME
    2. Copy encrypted file(s) to ms0:/enc/
    3. Execute EDecrypt on PSP
    4. Press X to decrypt file(s) or [] to decrypt and patch file(s) for m33

    Version history
    ===============

    - if output buffer allocation failed, EDecrypt will now try to use unsafe method.
    It may cause unpredictable bugs, but it's better than nothing

    OK, I will peek into the issue this weekend as it appears to be IE-related... my FF downloads it fine, but IE doesn't.

    Edit: It should now be fixed!
