Nobody asked me what MAME version I was using. He asked about the ROM version. And I am using the latest release, MAMEUI 0.144 (not counting the "u" updates). And it wouldn't have mattered to him because he was obviously unaware of the sound regression as was I since it wasn't listed anywhere, otherwise he would have mentioned the sound regression. Now I know that the sound problem was fixed in the "u1" update of my version. I normally update my MAMEUI on "whole numbers" (or whatever it's called) instead of every week with the "u" updates. I didn't realize there was a sound regression since it wasn't listed as a bug nor in the WIP of mameinfo.dat. But thanks for informing me that it was fixed and explaining why it wasn't listed.
