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!
