' Title: split.vbs
' Visual basic script to split atj2127/atj2129/1tj2123 fwimage file into its separate files
' Usage:
' - Copy to a text file on Windows.
' - Rename to split.vbs
' - Create clean folder
' - Copy fwimage.fw and split.vbs into the empty folder.
' - Run / double-click split.vbs
' - A fillist.txt file is created containing all files in the fwimage
' - plus all files are extracted form the fwimage in 512 byte blocks!
' - Due to the fixed 512 byte block size extra 0x00 bytes are appended to most files
