MK802 III: USB Gamepads

I did not buy the MK802's for gaming.  I have a Windows VM that has HDMI output connected to the TV for gaming.  My buddy (who has the original MK802) asked me to check if the USB SNES controllers worked on the 3rd generation MK802.  I plugged the controller in and installed Gamepad IME to test out basic functionality.  I installed an emulator, mapped the buttons and fired up a ROM.  The controller worked perfectly.  I didn't do exhaustive testing; I played Super Mario World for 2 minutes just to prove that it works.  On a related note, the game did have minor lag from time to time.  Overall, that game was playable.  I noticed the performance difference between running the emulator on the MK802 vs running the emulator on Windows (which is being emulated, hehe).  I will stick with running emulators in (emulated) Windows.  It would be handy to have my emulated games on the go.  I will wait until a more powerful USB stick computer comes out, though.
