There is something I can't understand about the length of the filenames and where the data of the file starts, but it's not a problem since we can use a work-around to guess it.

So this script for quickbms simply dumps the data without the useless "IMAG" "Rev " header:

Code: Select all

endian big
idstring "SDASSETF"
get DUMMY long  # 1
get FILES long
for i = 0 < FILES
    idstring "BMAP"
    get DUMMY long
    get DUMMY long
    get SIZE long
    get NAME string
    findloc OFFSET binary "IMAG"

    math OFFSET + 0x14
    math SIZE   - 0x14

    log NAME OFFSET SIZE
    math OFFSET + SIZE
    goto OFFSET
next i
But I have no idea how to open/read that image.
Feel free to ask in the Graphics section.
