Now unzip the sweet fx folder copy all contents inside the main folder and paste them into the jedi academy folder with the exe.
Finally install the sweet fx configurator as administrator make sure the folder is on your desktop. Once installed you can launch the application from the setup exe. Youll need to have admin right when you launch the application....I just right click compatibility mode and check the run as admin then apply.
Now launch the configurator it will be blank at first..u need to go to bottom left and click add game then find the ja exe sp and load it.
Now click on add load game at the right top of application. Once thats done you should see the words active next to the jedi academy exe you loaded. From here its tweak city you can mess around with the setting to get a look you like.
