!Flash is a plugin for WWW browsers that enables you to view Flash files. Many commercial sites use this format to make their site more attractive. Besides showing nice pictures and clips the Flash object also allows you to navigate through a site, therefore, without the right plugin it was most times impossible to get past the "Get Shockwave" logo while running a WWW browser. Although we now have the capability to view flash files not all sites will allow us to enter because they test for other required features or do not detect the !Flash plugin.


The latest version is 0.410.1.1 30 may 2001. Here is a changes list with all the major and minor changes made to !Flash.


The Flash file format is created by Macromedia® for distributing internet content. They also develop tools for creating flash objects.

The !Flash plugin is a port of the Flash Plugin for Linux which was developed by Olivier Debon and Fabrice Bellard. If you have any trouble with !Flash please do not contact them because they have nothing to do with !Flash.


!Flash is released under GNU General Public License. Check out the pages of the Free Software Foundation for a more detailed description about this license.


To use !Flash you need a lot of memory. In practice this means it will only run on a machine with RISC OS 3.5 or higher. For a simple Flash object you need around 2 Mb. You will also need the nested window manager (version 3.98 or higher). You can get the nested window manager from the following sources: See the readme files on how you should install/upgrade !Boot.

As of version 0.49c you will need at least RISC OS version 3.5. For users of older RISC OS systems the old version is still available.

!Flash has been reported to work on

If you have succeeded running !Flash on some other hardware please email me so I can extent the list.
