Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "*.cfg" file in the "profiles" sub-directory in the game directory. Change the "Developer" "0" entry to "Developer" "1". Note: This must be done prior to each time the game is started.
Also, locate the "enabledevice "##mouse" line in the file. Any of the previously listed codes can be inserted directly below that line as follows.
