rougegps, after inspecting the THSNTE.JCV file you provide, I've discovered why it wouldn't work
with the English map of TSM9. The reason is because the file is NOT the English version of JCV
but the Thai version renamed to be THSNTE.JCV.
Just check the file with the Thai THSNTT.JCV and you'll see that it is exactly the same. A simple
way to check is to zip/rar them into a zip/rar file, then open it up in winzip/winrar and
look/compare the CRC32 values.
If your THSNTT.JCV is different, then maybe they switch them up and rename the files incorrectly.
In this case, can you also upload your THSNTT.JCV file as well?
