A little early, but there has been a ton of activity in the last few days, so now is the right time for an update. What's new? Over 40 MAMETesters bugfixes, for a start! Read about the rest of it in the whatsnew.
Edit: due to an unexplained glitch, I had to break this patch into two pieces. Apply them both. If you already tried to apply the original single patch and failed, then simply applying the second part should give you a working result. Sorry for the inconvenience!
