One industrious modder out there has created a simple program so you can use your PS3′s SIXAXIS controller on a PC like a game pad. Here’s what you’ll need to do:
1. Download
this archive and install the filter driver (libusb-win32-filter-bin-0.1.10.1.exe).
2. Unpack ps3sixaxis_en.exe
3. Plug the SIXAXIS into your PC.
4. Run ps3sixaxis_en.exe once.
5. Push the PS button on the SIXAXIS once if it doesn’t see it straight away.
Unfortunately, the motion sensing features aren’t possible on the PC (not yet as least). But still, this is pretty easy way to net yourself a free usable game pad.
