Looking for a Bluetooth Dongle of Some Sort

I built a gaming PC a while back and I've been playing on a PS2 Emulator lately. I use the Motionjoy Application for the Controller but the thing is my Gaming PC that i built doesnt have any bluetooth capabilities from what im aware of. but Sometimes I get lazy and i want to lay down so when im gaming. instead of using my PC monitor i connect another HDMI to the TV cause they are close to each other.

My Question is this,

What Bluetooth dongle is great for the Motionjoy Application? im currently using a USB Cable to connect the PS3 controller.
