made a bms script for fun to try mimic the Gmad extractor program.
the script will decompress and extract the files from gma on the fly, only tested on a couple so far.

Code:

# script for QuickBMS http://aluigi.altervista.org/quickbms.htm

//Decompression
comtype lzma_dynamic
get ZSIZE asize
get FOLDER basename
clog memory_file 0 ZSIZE ZSIZE

//Extraction
idstring -1 "GMAD"
get FORMAT_VER byte -1
get STEAMID longlong -1
get TIMESTAMP longlong -1
get ZERO byte -1
getct ARC_NAME string 0x00 -1
getct DESCRIPTION string 0x00 -1
getct AUTHOR string 0x00 -1
get ADDON_VER long -1
for i
   get IDX long -1
   if IDX == 0
      break
   endif
   get NAME string -1
   get SIZE long -1
   get ZERO long -1
   get CRC_ long -1
   putarray 1 i NAME
   putarray 2 i SIZE
next i
savepos OFFSET -1
math FILES = i
for j = 0    getarray NAME 1 j
   getarray SIZE 2 j
   string NAME p "%s\%s" FOLDER NAME
   log NAME OFFSET SIZE -1
   math OFFSET   SIZE
   goto OFFSET -1
next j
