Thanks, me and DahBlount are looking into it now.
[Edit] It looks like FSO isn't even loading up mouse-sct.tbm. Are you sure you saved it as a .tbm and not a .txt?
Some editors, such as Microsoft's Notepad require you to change the file format, even if you put a file extension on the name.
Try using the two attached files. Place the mouse-sct.tbm in /data/tables/ and mouse_script.cfg in /data/config/
Note, to enable/disable the mouse-as-joy script in-game, you press the middle mouse button.
