ok, here is the progress
i have been able to set up a layout.lay (no background) and an atari2600.lay as i have an atari2600.ini
the layout is fine, so i know they are now switching, however the background for the 2600 (atari2600.jpg) is not showing up in mamewah, it is however showing up in the layout designer.
in mamewah i have just got a grey screen background when i change to the 2600.
progress is being made, but still need some extra help

thanks for the assistance so far guys
