Crash The Wrath Of Cortex Model Ripping HELP!

[harley201]

I wrote a BMS script to extract the files. Use it with QuickBMS

Code:

endian big //seems like idstrings are little endian but other values are big endian
idstring "0CSG"
get fileSize long
idstring "LBTN"
savepos RelativePos
get fileLengthPos long
xmath fileLengthPos "RelativePos + fileLengthPos"
get fileStart long
savepos RelativePos
xmath fileStart "RelativePos + fileStart"
savepos fileTableStart
i = 0
do
    savepos fileTableStart
    get fileNames[i] string
    xmath i "i + 1"
while fileTableStart != fileStart

x = i
i = 0
for i = 0 < x
    goto fileStart
    get magicID long
    get fileSize long
    savepos RelativePos
    log fileNames[i] fileStart fileSize
    xmath fileStart "fileSize + fileStart"
next i

script's note:
This is a pretty crappy script, it does a lot to achieve so little lol

Strange, I did everything correct but I got a error stating "Error: invalid command"xmath" or arguments -1 at line 7" I will see what the problem is but I bet I will fail to find it
