Yes they do
To connect a XBOX360 wireless controller to your PC you need this: http://www.walmart.com/ip/Microsoft-Wireless-Gaming-Receiver-Xbox-360-Xbox-360/5156486
To connect PS3 controller to your PC, I think you just plug it in with standard usb-to-mini-USB cable?
If you have a wired xbox controller, you can plug it in via usb, if you have a wireless you must have the receiver mentioned above. this is true with modded and unmodded controllers.
You are correct, there are 2 programs needed to make the ps3 controller work, and it dosnt work very well.
Hey Slick since it seems to me that you know alot about these controllers, can I use a plug and play cord with this?? I already ordered the wireless adapter from amazon, but im wondering cause I got a rechargable battery kit that has every thing that you need to keep this bad boy charged. I am going to be using this just for PC, I dont have a Xbox.
I just hooked mine to my computer via the play and charge cable and it is charging! .. I think it will be a good investment, these modded controllers love eating batteries up! I am not familiar with the PS3 Rapid fire software, But I am willing to bet they are very similar if not the same.. I would suggest going to viking360.com and going to the ''download'' Link and click ragnarok and downloading the rapid fire software, you can still play with it even if you do not have your controller yet.
