These Arcade Bezels provide the impression of (more or less heavily) used arcade machines, which I particularly like. This is a relaunch (WIP) for platform-independent MAME layout files (reset of GitHub history).
Parallel Retroarch Repository:
I plan to build up a parallel repository for Retroarch overlays here: https://github.com/estefan3112/Retroarch-Realistic-Bezel-Artwork/blob/master/README.md
You will find here:
Artwork for the official MAME distribution, which is an adaptation of John Merrit's artworks for RetroArch/Retropie: https://forums.libretro.com/t/arcade-overlays/4084
Further artwork to arrive from Orionsangel as discussed here: https://forums.libretro.com/t/my-realistic-arcade-bezels/10604 These .lay files aim to be platform independent and bare bone (with exceptions, where choice is nice).
I also included a template default.lay file, from which it is easy to build new layouts.
Explained for MAME on my Blog for MAME on modern Macs: https://mameonmacs.blogspot.co.at/2017/02/porting-retropie-artwork-to-official.html
Main contributions of this repository are:
(1) All bezels are based on 1080p (original contributions). Altough I scaled some of them up to 4000 x 2250 pixels, I will revert back to 1080p because scaling up adds no value. If the screen resolution is bigger than 1080p, MAME automatically scales up.
(2) MAME Bezels are typically split into cabinet and screen, so that you can switch between Clear Screen and Scratch Screen inside the game. A showcase for MAME's great bezel design. If the screen is too blurry or too clear for you, note that all screens have an alpha value, which you can edit in the default.lay file. Thereby you can make the screen more or less transparent. Apparently, this does not apply to the Clear Screen setting, where there is no screen overlay at all.
(3) This repository aims to be platform independent. MAME .lay files should work all over, whereas Retroarch needs dedicated config files for every system. This will also explained in the parallel repository.
(4) I also started to smoothen screen borders. Example is the new Berzerk overlay upload as of 21 November 2018. If John Merrit's bezels require refinement, then these would be the screen borders. See yourself.
A general note as regards Screen Size in these Layout files: As explained to me by John in a post, nearly all traditional Cabinet monitors are 4:3 aspect ratio. Even if the game provides for a different internal screen resolution, they were displayed in 4:3. Although this results in distortion in some games, only this seems to provide the view of the original.
This is work in progress, more artwork to arrive. It takes very long because I am doing a lot of testing before I am satisfied with the results.
