I really like the addition of the MESSUI software list in MAMEUI 0.180. I wasn't expecting new features. Awesome job guys!
In other news, I cloned the "master" branch and got a bunch of error messages during linking. Errors also happened when I cloned the "0.180" tag branch. I can post the errors if you're interested, but at this point I just download the official build if my build doesn't work.
My buildtools are completely up-to-date with mamedev.
