Cowon Z2 Bluetooth Question

[vernacular]

I have heard of it pairing with headsets, but can the Cowon Z2 pair with other bluetooth devices such as video game controllers?

I have seen videos of people playing games or emulators on full screen using a paired bluetooth controller with an Android device, but I can't find any mention of a Z2 or D3 doing this or even running an emulator for that matter. There are a few demonstrations of Z2 running games, but I've only seen a demo of a Cowon Q5W running an emulator and playing with a USB game controller. I am new to Android and I'm not sure how Cowon's OS differs from others.
