Asteroids Deluxe with Backdrop AND Bezel in MAME

[sirbeers]

I couldn't find info on how to do this so I'm sharing it.

Download the backdrop on this site: -->Downloads-->Game Media-->Arcade-->Asteroids Deluxe & Space Invaders - MAME Background / Backdrop

Assuming you already downloaded the stock bezel through the GUI, you just need to add astdelux.png to the artwork folder 'astdelux.'

Edit the default.lay file to this:

<!-- astdelux.lay -->

<mamelayout version="2">
    <element name="bezel">
            <image file="bezel.png" />
      </element>
    <element name="backdrop_a">
        <image file="astdelux.png" />
    </element>
    <element name="overlay_a">
        <rect>
            <color red="0.6" green="1.0" blue="1.0" />
        </rect>
    </element>
    
    <group name="backdrop_only">
        <element ref="backdrop_a">
            <bounds left="2" top="0" right="14" bottom="9" />
        </element>
    </group>
    <group name="bezel_only">
        <element ref="bezel">
            <bounds left="0" top="0" right="16" bottom="9" />
        </element>
    </group>

    <view name="Upright_Artwork">
        <screen index="0">
            <bounds left="2" top="0" right="14" bottom="9" />
        </screen>
        <collection name="Overlay">
            <element ref="overlay_a" blend="multiply">
                <bounds left="2" top="0" right="14" bottom="9" />
            </element>
        </collection>
        <collection name="Backdrop">
            <group ref="backdrop_only" blend="add">
                <bounds left="0" top="0" right="16" bottom="9" />
                <color alpha="0.3" />
            </group>
            <group ref="bezel_only" blend="add">
                <bounds left="0" top="0" right="16" bottom="9" />
                <color alpha="1.0" />
            </group>
        </collection><element ref="overlay_a" blend="multiply">
            <bounds left="2" top="0" right="14" bottom="9" />
        </element>
    </view>
</mamelayout>

Probably not the cleanest way to do that...but overlay, bezel AND backdrop display at once!

In case you want them, here are the mods I did to the .ini file for the game (vector upscaling, etc):

I really enjoy the game SO much more like this! Hope you do too!

oops I had a couple of things wrong in the .lay file do this instead!

any idea how to do this in retroarch?  I've got the megabezel reflection shaders, and FBNeo core running vector games in HI-RES mode.  Would love to be able to get the background artwork in there somehow.
