      @fomt the scripts slightly change the aspect ratio of the games so wouldn't be compatible with any overlays you have as they presume the standard aspect ratio. you'd get stuff overlapping, etc.

        @dankcushions ok, then I guess I can overwrite the files with yours and skip the overlay images.

          Hi all! I'm wondering if I can apply this method to the picade cabinet I'm working on - The resolution is 1024x768, and I'm going to be using MajorDangerNine's romsets from here:

          https://retropie.org.uk/forum/topic/20348/all-in-one-overclocked-rpi3b-arcade-rom-set-setup

          This uses FBA v0.2.97.44, MAME 2003 Plus, and MAME 2010.

            @Aksen Shaders work best at 1080p. With that low res, I don't think it's worth using shaders.

                @dankcushions I tried to get the console configs for the x768 resolution and the link is broken; my TV uses an odd 720p resolution (the previously mentioned) and I want those bars gone :)

                  all the cfgs are available here: https://drive.google.com/open?id=0B_51EcTfJiTqME44R3E3ZU5kdFU

                  however they won't work as per https://github.com/libretro/RetroArch/issues/7536

                  i need to fix the script and rebuild them all but my (tiny) protest about how retroarch handles unneeded and (IMO) foolish config changes like these is to not fix the mess they create (i probably will once they actually respond to my issue, though)

                    A temporary workaround of what changed and needs to be modified in the script can be found in this thread in the last post.

                    Here's a link to the script. You can use something like Notepad++ to make the modifications. It's only a few lines and it works well.

                    I could upload them. I think I have a few scripts modified for the mame2003/FBA and mame2003-plus/FBA changes using either the crt-pi or zfast shader.

                        Hello again. Last time I used these configs for my 1080p I didnt really know how to use them, i had ”core privided” to every game so I guess these configs never worked. 😵
                        Now i’m want to use them on a new install, and I have put them in the desire folders, and the shaders are working. If I change from ”core privided” to ”custum” in retroarch then I think the aspect ratio works to. Am I doing it correct? Should I have it on custom only or should I also have ”integer scale” on?
                        If yes, how do I set ”custom” as default? As now I have to change in every game. Should I edit retroarch.cfg?

                          Think I must change:
                          aspect_ratio_index = "22"
                          to
                          aspect_ratio_index = "23"

                          EDIT:
                          Yep, 23 works, custom must have been changed from 22 to 23

                            should I add "video_scale_integer =true" in /opt/retropie/configs/arcade/retroarch.cfg ?

                                @dankcushions No? What should I do then?
                                So then I guess integer scale should be OFF?

                                  @fomt integer scaling is off by default in retropie, so you shouldn't have to do anything in that regard. i think you should scroll up a bit to see the recent discussions about retroarch's config changes. specifically: https://retropie.org.uk/forum/post/183831

                                    @dankcushions ok, shall read. Red on another forum that they added a new aspect ratio to the index. so the custom 22 has moved to 23 instead.
                                    So I just run in powershell:

                                    Get-ChildItem 'f:\cfg\*.cfg' -Recurse | ForEach {
                                    (Get-Content $_ | ForEach { $_ -replace 'aspect_ratio_index = "22"', 'aspect_ratio_index = "23"' }) |
                                    Set-Content $_
                                    }
                                    

                                    then added them do the dirs in retropie, works great..

                                      @fomt - Integer scaling would interfere and takes priority over the custom viewports so you would want to leave it off. As @dankcushions pointed out it's probably off unless you turned it on.

                                      You already found the index change but also make sure you're in .cfg files are in the correct directory /opt/retropie/configs/all/retroarch/config/MAME (0.78) or /opt/retropie/configs/all/retroarch/config/MAME 2003-Plus. That was a change that happened at some point too.

                                      If they are in the correct directory and you're using the correct index it will automatically show Custom due to every .cfg files basically is a custom viewport with a shader.

                                      If you it doesn't show Custom but the shader or an incorrect shader is working then it's probably been enabled on another level like the global, system or ROM. It shouldn't be set in core as these custom configs are core level.

                                      I guess also it might show Custom but be incorrect due to integer scaling. Basically in certain scenarios the video options don't display accurately depending on combinations of options set or also some backdrops will force resolution changes too.

                                        @Riverstorm Thank for the info
                                        @dankcushions On another TV the screenmode is 1360x768. Tried to create cfg's with the script but I only got this in the config files,

                                        # Auto-generated crt-pi.glslp .cfg
                                        # Place in /opt/retropie/configs/all/retroarch/config/mame2003/
                                        video_shader_enable = "false"
                                        

                                        Do I have to change something in the script?
                                        Or if you have time to create a zip with 1360x768 I would be thankfull

                                        EDIT:
                                        It appears that my TV can handle 1366x768 resolution, so I will download those configs instead.

                                          @Riverstorm Could you please upload those modified scripts for the zfast shader, it'd be a real help.
