After various PinMAME releases (...1.57, 1.58, 1.59) and the latest 1.60, a 2.00 version was released at PD. I don't know how much has been updated in this one, as I didn't join it yesterday, but they made a big jump from 1.60 to 2.00 immediately. I will probably join the torrent today, and see how big the difference is.
