I don't understand the full format of this archive.
The following is what I wrote and is both incomplete and wrong (it's full of lame work-arounds that don't work):

Code:

get PDE_SIZE asize
math OFFSET = 0x1000
math SIZE = -1
set PATH string ""
set NAME string ""
callfunction EXTRACT

startfunction EXTRACT
    string PATH  = NAME
    string PATH  = /
    savepos RET_OFF
    goto OFFSET
    savepos BASE_OFF
    if SIZE < 0
        get LIMIT asize
    else
        xmath LIMIT "OFFSET   SIZE"
    endif
    do
        savepos TMP
        if TMP >= LIMIT
            math TYPE = 0
        else
            get TYPE byte
            getdstring NAME 0x6f
            get TSTAMP longlong
            get OFFSET long
            get SIZE long
            xmath OFFSET "(OFFSET * 0x1000)   0x1000"
            xmath TMP "OFFSET   SIZE"
            if TMP u>= PDE_SIZE
                math TYPE = 0
            endif
            if TYPE == 1
                set FNAME string PATH
                string FNAME  = NAME
                log FNAME OFFSET SIZE
            elif TYPE == 2
                callfunction EXTRACT
            else
                math TYPE = 0
            endif
        endif
    while TYPE != 0
    goto RET_OFF
endfunction

Strange format and data seems compressed. comtype scanner give no good results. I found some functions maybe help us.
