Anyone can compile the updated version of MAME with the Mameui front end at:
https://github.com/Robbbert/mameui.
He updates it frequently, the latest code is from a couple of days ago.
If you want an updated compiled version I recommend you try Mysticum Touch by Guido Marquardt:

You can find my artworks, the best plugins to play with Millennium and Certabo boards and the latest MAME updates.
