![]() RetroArch has pretty powerful tools for creating overlays, as you can make fancy ones with working controls overlaid for touchscreen devices. For our example, let’s call it /home/pi/mame-overlays/simpsons.png. Save the image as a transparent PNG and put it in the overlays folder on your Pi. – Now delete the emulator screen placeholder so you’ve just got a transparent image with the bezel images in the right places. Then do the same with the distances of the emulator screen from the left and the top of the image – distances C and D in the diagram. – Measure the pixel dimensions of the emulator screen, which are A and B on the diagram, and note them down somewhere. The green is where you want the emulator’s screen to be, and the red is the instructions, bezel images and so on. – Paste in the images you want for the bezels etc, and move the images and the screen placeholder you just made into whatever arrangement you like. Colour the rectangle in whatever bright colour you want – it’s just there as a guide. The size isn’t crucial, but particularly if you’re using shaders you might want to make it a whole multiple of the game’s original resolution. In a new layer, make a rectangle to represent the screen of the emulator. – Go into Photoshop/GIMP/image editor of your choice and make a new transparent file of whatever size your screen resolution is. ![]() cfg file in the rom folder for each game, which tells Retroarch which overlay to use and where to draw the screen. For our example we’ll use /home/pi/mame-overlays. cfg file for each to tell Retroarch what to do with the image. This will contain an image for each game with that game’s bezel artwork, and a. ![]() – an Overlays folder somewhere on your Pi. For an example, let’s say we’re making artwork for the Simpsons arcade game, which is simpsons.zip in your roms folder. I love getting the bezel artwork just right on my arcade games, and with the RetroArch versions of MAME and FBA it’s very customisable.
