Selected Test Results (selected in 'Test Results' table below)
Almost everything: normal gameplay, opening books, position editing, game analysis, handicap play, and file reading. All usual functions work smoothly.
What does not
Some icons don't show correctly and so the move arrows don't have heads. Board design in plain colors result in a blackened board. The Engine spite effective is rather slower and less powerful than in a native Windows installation. Some menus behave strangely affecting visual effects such as compiz. Some settings are not remembered upon program restart such as board design and window size.
What was not tested
Engine matches through COM ports.
