MESSUI 0.193 and MAMEUI 0.193 have been released and are available at the usual place:
There's no release of HBMAME.
- The download of MESS and MESSUI is now a full package with all needed files. There's no need to download MAME as well.
Note that the release of MAME is delayed due to an issue with bgfx. I didn't wait around for a fix, so it's recommended to use D3D at this time.
