Well here's what you can do (this probably isn't the best way, but it works):
Open gsd1.bin in WindHex.
Search for the hex value: 1F8B08 (gzip files always start with this header)
Write down the offset (it's 14000)
Search for hex value 1F8B08 again.
Write down the offset (it's 10E800)
Now,
Edit -> Dump Binary DataEnter file name:
va1.gzStart Offset:
14000Ending Offset:
10E7FF (you should subtract 1 from the offset you wrote down.)
and that will extract the first compressed file. Then you can use
7-Zip or WinRAR to extract the gz file.
Then to extract the second file you do pretty much the same thing:
Write down the offset (it's 10E800)
Search for hex value 1F8B08 again.
Write down the offset (it's 1C8800)
Now,
Edit -> Dump Binary DataEnter file name:
va2.gzStart Offset:
10E800Ending Offset:
1C87FF (you should subtract 1 from the offset you wrote down.)
Now just keep doing that for all the files. I think there's 226 files in that 1 archive... Errrr hope you don't go insane extracting them all. If you were a programmer you wouldn't have to do it this way.
