Comment (by FranceBB):
Using gsar to modify the header also works and makes the files possible to
decode like so:
type "INPUTFILE" | C:\temp\gsar.exe
-s:x83:x09:x40:x00:x00:x00:x02:x80:x01:x03
-r:x83:x09:x40:x00:x00:x00:x02:x80:x01:x02 -F | C:\temp\gsar.exe
-s:x60:x0D:xC0:xDE:x00:x00:x02:x80:x01:x02
-r:x60:x0D:xC0:xDE:x00:x00:x02:x80:x01:x03 -F > "OUTPUTFILE"
Still, I believe this should be addressed anyway without using gsar.
