Mr. RetroLust

I don't really have the time to make a tutorial but i'll try to write it down as good as I can. I'm using an older version of RetroArch so it probably wouldn't be the same for you where the settings are or maybe renamed but this is what I do. All I can say is you'll load the preset (.cfg file) in the "Quick Menu" under the "Onscreen Overlay" tab (Also set Overlay Opacity to 1.00 to make it fully non transparent), then you go to the video options and there you'll use Custom ratio X pos for the x position, Custom ratio Y pos for the y position, Custom ratio width and height, after you are satisfied you'll go back to Quick Menu and scroll down to "Overrides" then choose Save Content Directory Override and it will save the bezel and the size and position of your game screen in a preset for the directory where your games are stored. You also may want to use a shader effect that curves the screen and adds scanlines to your liking, I use crt-easymode-halation myself.

Yep thats what I ment, you can read all about the effects in mame on this page, justvtake your time to suck it all in: https://docs.mamedev.org/advanced/hlsl.html

I see what the problem is now, your screenshot of 1942 shows the gameplay screen entirely flat, at the start of our conversation I told you I use an effect in mame to curve the screen, you can also add scanlines and other effects. Im not at the pc atm but im sure a google search will help you on your way, search for "Mame apply scanlines" or something, In the downloads section of this project I also added my mame effect presets but they might not work with newer mame versions as I use version 0.198, in that case if you open the presets with a notepad editor you'll see what I used for effects and the curvature amount.

I think you just have to adjust the width and height of the game screen, adjust the x and y coordinates to the new size of the game screen and thats it. I dont understand what you mean by losing the curved look as that should'nt happen.

You can find You can find loads of tutorials on youtube how to use overlays in retroarch. You'll need to size them yourself.

Ah ok, you can adjust the height, width, x and y position in the .lay file included in the zip file. Just open the file with a notepad editor.

When you bend it with the curved CRT effect you'll see more of the text because when the game screen is flat the bezel will cover the text.

Make sure "artwork crop" is disabled and also use the mame effect setting to bend/round the corners of the screen. @fazmeister See also:

Not sure if it works for you in this case, but always make sure both displays have the same windows dpi text scaling set. This fixed the issue for me in the past.

What I use is an effect in mame to bend the screen, this will help you see more of the screen.
