    I have just got the PAL version of Second-sight. I found out how to use a simple gameshark code to convert to NTSC, but I need a master code for that. Does anyone know how to find out the (M) code for a game?

    you need the .elf off the disc and a program called ps2dis.

    open the elf and invoke the analyzer. then scroll down from the entrypoint (usually 0x100008) untill you find a jump and link to main (should be the next jal after FlushCache). take that address and use it with data 0xE with the F0 master command.

    ex:
    001000F8 0C045678 jal $0024673C (main)

    master code would be:

    F01000F8 0000000E

    or you could also just use the 90 command with the memcpy jal inside scepadread address and data.

    ps2dis makes the codes raw/hex you will have to convert the codes for them to work...

    theres few mothods to find the code...

    1. You have to load the Elf - File in your ps2dis. It brings you to the start Adress. If the game have an Entrypoint, normally it is similar to the Start Adress. But you can also go the Option "Jump to Labels" and searching for "Entrypoint" (Without " " ).

    if the code is like so 10250039 46604476

    A normal Mastercode have to start with a "F" in front of the Adress. So we change the First Number ----> = " F 0250039" .

    so to complete the code we do this

    F0250039 0000000E or this F0250039 000001FD

    Important:
    Actionreplay/Gameshark doesnt use "Entrypoint" - Enables/ Mastercodes. Entrypoint is specific for Codebreaker / Xploder!


    2. First we open the Elf - File and go to the Option "Jump to Labels". Now we search for Label "memcpy" (without " ")

    Example: GTC Africa

    Adress =" 0011e620 "

    but this is not the Adress we can use for a Mastercode. On the Adress we have to press Space + F3 to start Invoke Analyzer. The first time pas2dis bring us to Adress = "0011c32c" but this is also not our adress. We have to press F3 since we have found "scepadread" above or "scepadgetstate" under the "memcpy" Adress.

    memcpy Adress for using Mastercode = "00142f8c"

    We can use the 2 unlock Digits/Values but we can make a better Mastercode! We only have to add + 3 to the memcpy Adress ---> 00142f8c + 3 = 00142f8f
    Now just change the first number into a "F"

    Mastercode (memcpy) = F0142f8c 00142f8f

    Note: This type of Mastercodes Codejunkies use!! You can use this Method with all Cheatdevices!

    3. This method you have to use if the ELF-File doesnt have useful Labels.


    We can use all of the first 3 Jals starting from Start Adress. This Jals are called Main-Jals. If you have one of this Jals just put one of the unlock Digits/Values to it
    (dont forget to change the first number to a "F")

    Mastercode
    "Main-Jal + 0000000E/000001FD "

    I've read one of your reviews on the other site, you seem to own a copy of second sight. Maybe the methods mentioned above are too advance for me :). Would you try and see if you can get the mastercode for me?

    If you can get a y-fix code for that game, let me know.
