Sorry, but new MEWUI interface in Mame is simply ugly.
MameUI is far, far superior and easy to configure and it has the look and feel of a Windows program.
MEWUI is a too custom interface, it isn't meat or fish.
Mame for Windows should have MameUI option and not some multiplatform, strange ugly interface.
Mame is multiplatform, but his interface should be different in Windows, OSX, UNIX or Android. Same interface for all platform is simply ridiculous.
Long live to MameUI, the only real Mame on Windows.
