Space Empires V patch 1.74 released in June 2008. Fixes a number of bugs found since 1.71.
Old test results
The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
The main menus; UI sounds (though they're barely audible and are rather choppy - using ALSA, they don't work with OSS driver); starting a new game; basic 3D interface (though it's REALLY slow and planets tend to flicker as the map is rotated; requires use of native d3dxof.dll for this to even work!)
What does not
MP3 music playback (must be disabled in Data/Settings.txt in order to start the game); minimizing SE5 within the Wine window (seems to make the game freeze or at least not be restorable); star field backgrounds
What was not tested
Playing the game (it would be a real pain what with the slowness of the UI and the planets flicking in and out of existence as I rotate the map!)
The UI slowness issue is almost certainly a DIB engine issue.
