--- Comment #22 from Someone scrimekiler@yahoo.fr --- Sorry about that, I didn't have a clean wineprefix and it seems it was 64 bits.
With a fresh 32 bits Wineprefix, I see a logo instead of a black preview if I make a new savegame with both wine and wine-staging. But it still doesn't show a screen capture of the game.
