Hello all. I recently put together a new computer and discovered the joys of emulation. I'd really like to be able to play some of the four player games with friends. Unfortunately, I don't have a game port on my computer. I'm looking to use four fairly basic six button gamepads. What is my most cost-effective option. I have four empty USB ports. Should I pickup 4 of the MS Sidewinder USB gamepads (should total roughly $100). Is this possible? Is there a cheaper option? Maybe a 4 port PCI card? Any help would be greatly appreciated.
