Canyon Bomber: new mame overlay

[UDb23]

This Atari game is dated 1977 !
Still fun, especially for 2 players.

Actual arcade game had a grayscale screen with monitor bezel and an overlay below covering part of the screen.

The lr-mame overlay includes both; it was a bit tricky to get the right scaling and alignment to precisely match the game screen.

Have fun !

You can find this and other overlays in the rpie-ovl repository. And if you want an easy way to install them, @meleu created a great dedicated script.

git clone --depth 1 https://github.com/udb23/rpie-ovl.git
cd rpie-ovl
bash rpie-ovl.sh

After launching rpie-ovl.sh script you just have to follow the instructions in the dialog boxes. Once you have the rpi-ovl.shscript, choose the Update option to get all the latest art in the repository.
