Using MAME Overlays/Bezels and shaders with RetroArch in RetroPie
-
Off the top of my head, in principle you would remove 15px on top and bottom, and then 120px left and 120px right.
Would double check in action to make sure things fit - it might be the case that for some resolutions the Integer Scale causes it to be one integer less than in 1080p, and so the screen will actually be smaller than expected. In particular, if the integer scale multiplication of the vertical dimension resulted in a value between 1050px and 1080px, that won't work as intended. But I hope that would not be the case, as it's such a tiny difference. :)
Let us know how it goes.

@pjft Of course... :-) What I ask is if it is possible to do that in Retroarch (like the crop in-game menu video options in MAME) or I have to edit image in Photoshop. I have donwloaded John Merrit overlays pack and find out the game does not match in overlay window. Sorry but I am new in Retro arch. Thank you.

Ah, got it.
Unsure about how to do exactly that in Retroarch.
What you may try is what I recommended earlier on scaling the overlay accordingly. I honestly don't know how it's currently working on your resolution (I'm assuming it doesn't take up the entire screen real estate, but rather has scaled proportionally to its original size, restricted by your screen's resolution).
Open the Retroarch menu, > Settings/Options > Display Overlays
Then turn on/off the option that shows/hides the overlay in the menu so that you can see it.
Then change the scaling factor (which is currently at 1.00x I imagine) until it stretches to fit your game area as intended.
I don't recall the exact option names, but hopefully this helps.
-
Not exactly. This is my problem...
-
That's... weird. When the overlay is not showing, is the game screen not centered?
I suspect that may be because of you using the current config files which are configured to screen resolutions of 1080p. It seems there's an offset to the play area that would be the right one for those screens.
You may need to open the config file and figure out what the right numbers would be for that, and multiply by that formula for the X and Y coordinates - and then maybe apply some scaling.
For now, if you want to test it out manually in concept, turn on the overlay in the menu, and then go to Settings/Options > Video
There should be something with Viewport X and Y. Note down those two values.
Then Reduce X until it looks fine - the viewport (play area) should start to move to the left. Take note of the new number when it looks fine (to compare with the original one, and see what a formula might be to convert between the resolutions).See if it needs to be tweaked on the Y axis as well. Do the same - take note.
See if the overlay is hiding any of the play area, and if so, now go scale it. Take note of the new number.
In this particular case, I suspect the viewport X needs to be subtracted by either 120 or 240, and Y by 15 or 30 (depends on how it actually works).
You may try to adapt the previous script shared by Rion with that formula - instead of multiplying, subtracting - to batch fix that.
You may need to add the line to scale the overlay, if needed. I don't recall the exact parameter, but you may be able to get it from one of the original retroarch.cfg files.
Have a great weekend!

I hope somebody can answer some noob questions.
Ive got the program up and running, and everything works great.....except no overlays on the N64 or Mame show up. Any obvious things to look into?
Any easy way to add overlay files to the manager?
Thx

@Rion Did you get around to completing this? The resolution of my monitor is 1366x768 and I have successfully changed the resolution in all .zip.cfg files except for the ones that don't contain this information.

I finished my set of 1024x768 bezels and cfg's a while back. Just as batch crop followed by a resize action. Wrote a little script to recalculate the viewport size & position.
I haven't tested them all, but I am willing to share them anyways, if there is an interest.
Hi @Zigurana I'm just looking into this now and use a 1024x768 screen, if you could share your files that would be great. Thank you!

@Zigurana Thank you! These are great. I can't see the invaders.png included though. Could you send this across. As my bartop is invaders themed, this would complete it! :)

@Graboid :
Hey, you can Graboid them here, or at least once it finishes uploading (~3hrs for 126MB, sigh).I modified the ones below as they were too cropped. I added some detail back in, not original's but customised for myself. I plan to do some more also, especially for the vertical games.
-
@Graboid nice!
I'll try and find the space invaders one, when I get a chance. -

@Graboid Here's a Space Invaders overlay (+ other classics).
It's intended for 1080p and maximum playable area but it shouldn't be difficult to adapt to 1024.Thank you! If you don't mind I'll try and convert your awesome creations to fit 4:3
-
@Graboid Sure! Glad you find them useful.
-
@Zigurana Do you have a copy of the 1943.zip.cfg file that resides in the ROMS folder? Mine doesn't fit properly, mainly the top and bottom are not fitting properly.

Hi!
So I installed the rp-video-manager and the arcade overlays work well.
Only one question, I would like to apply that but without the scratches and reflections, so could it be posible to download the artwork in psd format or whatever where I could eliminate some layers and mantain the ones I want?
Many thanks for the hard work!

Hi @Floob
I have a 4:3 and want to have a few for vertical games.
Is there some way I can make the overlay to maintain proportions, center the image?
Maybe something to do with overlay0_rect ?
EDIT: yup, that was it.
This looks ok on my 1280x1024 monitor:
overlay0_rect = "-0.22,0,1.44,1"
That is the positioning left, top, right, bottom. note that the padding on the right should be twice the positioning on the left to center the image. The unit is screen lengths or heights, "0,0,1,1" is default - the left side starts at the 0column of the screen, the top starts at the 0 row, and ends at the row that is 1 full screen length down, and 1 full screen right. If I placed "-1,0,2,1" I am telling the png to start at the column that is -1 screen to the left (1 full screen away) and the 2 is 1 screen length past the right side (the actual screen legnth is 1 plus 1 extra is 2).
This will be added to each of the CFG files found in \\RETROPIE\configs\all\retroarch\overlay\arcade-bezel-overlays
In the rom.zip.cfg, found in the roms folder, I am playing around with the height and width. so it looks ok. I found that
custom_viewport_width = "656" custom_viewport_height = "875"
works well for this screen, when you are in a vertical game like 1943. Then to center the CRT monitor take the screen rez, subtract the width and height, then divide it by two.
I'm hoping there's a proportional/center toggle, so I don't have to do this.
