Hey reading over the wiki it says:
Bezel Background:
RocketLauncher will search for a background image to be drawn below the emulator window and the bezel image. This search is independent of the bezel image search, so you can have only one background defined to all your Nintendo DS games, and at the same time have different bezel images for each rom of the system.
RocketLauncher will search for any png image file beginning with the word Background to use as the bezel background. If more than one background file is found at the same folder, RocketLauncher will choose aleatory which one to use at each game section start
The folders order to be searched is the same as the bezel image locations explained before:
.\Media\Bezels\Nintendo DS\Super Mario\Background*.png
.\Media\Bezels\Nintendo DS\_Default\Vertical\Background*.png or .\Media\Bezels\Nintendo DS\_Default\Horizontal\Background*.png
.\Media\Bezels\Nintendo DS\_Default\Background*.png
.\Media\Bezels\_Default\Background*.png
//
So I've done that and the image is displaying correctly under the emulator but its hidden. Is there something in MAME you have to do to allow the background image to display correctly underneath? For example, people have games like space invaders running with a background like this but in mine the background is hidden:
