Today brings version 0.184 of MAME, which I compiled under brand new MacOS 10.12.4 and Xcode 8.3. I am also very happy to report 10.250 pageviews of this blog, which is very encouraging.
Compile was flawless as always. Performance seems in line with previous versions, BGFX Metal bug is still here. So it seems fine for us MAME users to upgrade.
Page statistics show the clear need for shader documentation, in particular BGFX, as well as Artworks. Quite as I anticipated, and I will try to keep focus here. Thanks for your interest.
