Okay, I’ve been using this a lot myself but haven’t gone through the trouble of putting it up for other people.
If you have a game that takes an Xbox 360 controller, and you have a Logitech Rumblepad 2, you’re going to need an Xbox 360 controller emulator.
Here’s a great one. Download it from kiplange.com here:
Now, to get it to work, put the files (you don’t need to put the src folder or the test program in, though) in the directory where the game you want to play is installed. It should work perfectly. I’ve used this with tons of games and had no problem whatsoever.
