Dedicated to all Windows 98/Me users.
Based on Eclipse_v3 (lots changed).
Fully working on WMP9 and WMP10.
It "kind of" works on Windows 7 / WMP12, with a few bugs like it's not possible to resize the window, and do not even try to press the Maximize button because it will deactivate the skin. Those things and the fact that the menus are only in English instead of the system's default language make me doubt about using it all the time.
I wish I could find another skin for WMP12 with WMP11's appearance.
It works on 7 it has to be in C:\Program Files (x86)\Windows Media Player\Skins (just right-click wmp in the start menu then locate file), when it's done you'll be able to select the skin with the skin selector (View > Skin Selector ; you'll maybe have to select skin mode before having displayed the Skin Selector)
