Do you know if there will be a patch released, So a joystick can be used on STEF2?

You can install your joystick a follows.
Open the Global folder (found in the base folder of ef2)
change the joystick line to joystick 1 in the configuration files ( They open with wordpad )
That will allow ef2 access to the joystick
then open a new wordpad document or text document in the global folder, titled joystick.cfg
you can now type in the configuration settings found at http://www.chproducts.com/fom/cache/174/html.
It works for me!

OK, looks like the above link is not working, so here are the joystick.cfg details.
