To use Matador to create content for Flash Player 6, specify Flash Player 6 in the Flash tab of the Publish Settings dialog box (File > Publish Settings). You can specify ActionScript 1 or ActionScript 2 when publishing files for Flash Player 6. For additional information, see Determining which language elements are available.
Note: In Matador, publishing for Flash Player 6 is not the same as saving a file in Flash MX format. Some features that are available only in Matador may cause errors or work in unexpected ways when compiled in Flash MX. If you try to save a file in Flash MX format, a warning message will appear if you have implemented any features that Flash MX doesn't support.
