I got really tired of the HammerHead not saving my settings. So I modified the .inf file and got it to use the default generic hid usb interface, while keeping the force feedback part. You have to install it like all the other USB HammerHeads by going into the device manager and updating the USB Interface Device. I also modified the files so that hopefully it got rid of redundancy of InterAct's programming. It installs the drivers in your windows system32 directory under the folder InterAct, so it provides better uninstallation.
Note: the on/off button for rumble my not work when you first boot, just run a directx application and it will initiate by itself.
