Thanks! I was able to install the driver this time, but I somehow ended up with two controller profiles listed in the device manager: "Microsoft Xbox 360 Controller" and "HID-compliant controller." I tested them on Need for Speed II SE. The game recognized only the HID controller profile and all it could do with it was send force feedback. The buttons and sticks didn't respond. I am not fluent enough in Japanese to understand the readme file, so I probably did something wrong during the installation. Would you mind explaining step-by-step how you installed the driver? For instance, did you allow Windows to copy files from the Windows 98 CD?
