Space Invaders with Backdrop and Bezel in Mame

[sirbeers]

To get this to work the way I wanted I used invaders.png from Mr. Do's arcade. You can find it in the "Old Artwork" section of that site.

Put it into your artwork-->invaders folder. Bezel.png should already be there if you downloaded the bezels through LaunchBox.

Edit default.lay to look like this:

<!-- invaders.lay -->

<mamelayout version="2">
	<element name="bezel">
    		<image file="bezel.png" />
  	</element>
	<element name="backdrop_m">
		<image file="invaders.png" />
	</element>
	<element name="overlay_m">

	</view>
</mamelayout>

Enjoy!

This is exactly what I have been looking for.  Unfortunately mameworld.info seems to be down right now.  Can anyone point me to another background image this .lay works with?  I've tried the ones here https://forums.launchbox-app.com/files/file/3850-asteroids-deluxe-space-invaders-mame-background-backdrop/  but have been unable to get the backdrop to display correctly.

This specific game is a bit tricky to make it show-up correctly in MAME due to the "color  overlay" that MAME uses to display the red and green color portions of the graphics. Its all a combination of the color overlay, the blending, and the correct placement of the elements in the view in the .lay file.

That said its probably easier to share my version of the above artwork (invaders.zip) that supports two views Framed & Unframed and also a Glass on-off option under Video Options>Screen #0 for anyone that would like to use it as is or modified to his own needs.

invaders.zip

below is the lay file used in the above zip in-case some one wants it for reference:

It is tested with MAME 0.285 and a modified raster.ini file as below

# DIRECT3D POST-PROCESSING OPTIONS 

distortion                0.15

to fit the screen curve.

Hope that is helpful. 😄
