    WORKS FOR BOTH 5.50 GEN-D3 AND 5.00 M33-6
    MAKE SURE YOU DO NOT COMPRESS THE ISO OTHERWISE IT IS UNLIKELY IT WILL WORK
    MAKE SURE YOU USE A CLEAN ISO IMAGE
    WORKS FOR BOTH EU AND US RELEASES


    HOW TO PATCH:

    Download ISO_TOOL_V1.52_unofficial_by_dan here: http://www.megaupload.com/?d=QNMN9WG0

    Unrar it, and place the file in your PSP/GAME folder.

    Make sure the MGS game is where it's supposed to be (ISO folder),

    Turn on your PSP and start the ISO Tool, then:

    Move the cursor onto the iso.
    Press X, select decrypt.
    It will ask you if you want backup, say no.
    It will then ask you version patch say yes
    It will then ask you if you want to start, select yes.

    Once done, ensure cursor is still on the iso, press x.
    Select patch
    Select prometheus (not the recover one)
    Once done exit out of the app and enjoy!

    Credit to riin1979 for the guide and TaZz for informing me of it.

    I know for DEFINITE that this method works for BOTH firmwares, so if it's not working for you, you're doing something wrong.

    GEN-D3 Configuration Options recommended for Peace Walker:
    CPU Clock XMB/Game - Default
    UMD ISO Mode - M33 Driver No UMD

    For M33, Turn off "Speed up MS access" in the recovery menu before doing the Data Install. You can turn it back on after that's done.

    Other Notes: "Freeze" at the end of the prologue mission: Make sure you press R and look around at the end of the prologue mission or you'll think the game is frozen.

    For everyone still having issues try this crack:
    Metal_Gear_Solid_Peace_Walker_USA_CRACK_PSP-MRN
    mrn-mgspw

    Should only be applied to Metal_Gear_Solid_Peace_Walker_USA_PSP-pSyPSP release

    You need to confirm which release these instructions will work for...US, EU, or both versions? Additionally whether this will only work on a clean image.

    Netherlands, currently
    5.03 GEN-C = 5.50 GEN-D3 in terms of everything except it's not permanent CFW.

    Someone said they got it working on GEN-C via this method, so it should work.

    I'm about three hours in and no problems at all for me, using Eu Promo version, you're probably doing something wrong.

    I followed all the steps and compressed to CSO and it boots up fine. Haven't played yet.

    Having a small issue, I get to the cutscene where the sound effect CLICK comes up, I press R, and then it says its loading, but it sits there for like 5 minutes claiming that its loading, but its not.

    Wait! So, this tool applies the prometheus method w/o the long eboot decryption and replacement process? Or is this just for MGS:PW? (Widely used line coming up!) Sorry for the noobish question. Just want to clear that up.

    do you really need to do step 2?

    "Once done, ensure cursor is still on the iso, press x.
    Select patch
    Select prometheus (not the recover one)
    Once done exit out of the app and enjoy!"

    I used iso tool 1.51, loaded the iso (usa), x to decrypt then (no, yes and yes) and the game loads fine. Been playing for an hour and no problems so far on 5.50 Gen-D3 (slim2001)
