Honestly, I don't think any of us at Pim have the foggiest clue.
We don't find much time to play with stuff that isn't Raspberry Pi, and certainly haven't tried an ODROID U3 in a Picade. I'd suggest the best place to ask is the ODROID community forums, although you might get a useful response from a member here!
I don't know if this is useful: http://forum.odroid.com/viewtopic.php?f=91&t=17683
I've been playing with Lakka lately and it seems to be pretty decent.
