    ************************************************** **************************************************
    Max Size of rofs2: 33MB
    Max Size of rofs3: 13MB

    Priority: core<rofs2<rofs3
    Files will be placed in Z according to the priority basis
    ************************************************** ************************************************** *

    Some help:
    Various Mods and System Modifications are already available. See here. Place this mods in rofs2/rofs3

    To add applications use SisContents. Extract files from sis/sisx files and then place them in rofs2 or rofs3 respectivelty

    You can add any folder or file in rofs2/rofs3. Those files will automatically coppied to Z drive after flashing. To overwrite files in CORE (.coo) file, edit and place the files in rofs2/rofs3.


    Important Firmware Files Description

    UDA -----------> C:\

    Z drive comprises of:

    Z: - ROFS1
    Z: - ROFS2
    Z: - ROFS3

    Currently only rofs2 and rofs3 are open for editing. But CORE file in uncrackable untill now. So ROM cannot be edited.
