      all seems good to me... could you try the same with a fba_libretro game and his .cfg ? i haven't tried with mame, but it should be working the same way 😕

        I don't have fba_libreto folder in /system/configs/retroarch/ either.

        I just spent the two last hours testing this (even with fba_libretro rom), it still won't work.
        I can't explain why I have different configuration of the same rom using the same config file on both emulators (fba libretro and Mame).

        I activated the per-game core options, and I can't find anywhere a config file containing the options I activated for the given game.

        I don't understand. I'll try and search more and I'll come back to you if I find anything relevant. I'll also come back if I don't find anything (so that we can't set the topic as "Unsolved" or "Solved").

        Unless someone else has some other lead to follow.
        This sucks as I realize that despite video configuration I can't set up controls either (I mean game-specific controls).

        Thanks a LOT for your taking time helping me this one. I guess there is an option somewhere that is not enabled that prevents me for getting the same result as you are. Seems like it's something as "stupid" as that, but so far I haven't found it yet.

          hi, have you tried this ?
          https://github.com/recalbox/recalbox-os/wiki/How-to-use-custom-config-for-emulators-(EN)
          (set a configfile for a core, in hard in the recalbox.conf)

            Per game .cfg is a 4.1 only feature

              Yes, I did do that, and it actually works but it changes the settings for the whole emulator, not for the dedicated game.
              To be honest, given all the tests that I've done, I'm getting used to the whole "save a new configuration" and "update the recalbox.conf accordingly" thing !!

              @Substring
              Thank God ! Thanks for the info. I can stop the tests now ! I was going crazy.
              It's a relief that it just can't be done right away.
              I'll wait for the 4.1 version of Recalbox then.
              I have a micro SD card with an unstable version of recalbox in 4.1, I'll give it a test (so that I'm ready when the official 4.1 version is released).

              Thanks again to you all for taking time to try and help me.

              Given that I have an answer now (even though the answer is to wait for a while), does it fit with a "solved" status of the topic so we can close it ?

                you can install the 4.1 right now, its really stable. i'm on it since the launch weeks ago, haven't found a real bug yet.
                No reboot, no unexpected things. All flawless 🙂

                The stable 4.1 will not come in a near future i think 😕

                if you haven't done it yet, install you roms on a usb key like in this tutorial :
                https://github.com/recalbox/recalbox-os/wiki/Use-an-external-usb-storage-device-on-recalbox-(EN)

                This way it take only 2 min to reinstall a system, 4.1 or not.

                  That would explain why you can set per game parameters and I can't, you're on 4.1 already.

                  Thanks for the link to the USB storage thing.
                  As I understand, the purpose is double (correct me if I'm wrong) :

                  1. You can easily make a copy of your SD to a USB device (whichever it is) = make a ghost of your system
                  2. Allows to play from the USB storage instead of the SD card

                  That's the second part I'm not quite sure of.
                  I guess this allows to make some tests (that will be recorded on the USB storage) without impacting the data on your SD card, am I right ?

                    no, the real interest is in using the usb for the storage (roms, bios, save, config...)
                    in the ES menu you can choose your storage (internal, or external)
                    if you choose external, on the next boot the recalbox will use the usb files, and not the sd files.

                    For this you have to put a usb key, choose external, reboot. ES will create all directory on the usb key (recalbox/rom, recalbox/bios....)
                    you shutdown the system, take the usb key on your pc, and fill the directory with roms bios saves from your sd.

                    after that, you don't use your sd anymore for all the content of the "share" folder.
                    The SD will just be used for the boot and the ES system, and will be read only, so no more SD crashed or corrupted.

                    So, 1, you dont make a ghost, you make the USB your share system.
                    2, totally yes 🙂

                    SO security of your files, easy to transfer, and if you reinstall your SD card with a new install, you choose external stockage in the config, reboot with your usb key, and all your system will be the same.

                    Of course, the recalbox.conf, and all the confings/retroarch/ files will be on your usb key too 😉

                      I'm not in the mood to read the whole topic, but regarding per game resolution (and i do mean SCREEN resolution, not viewport or aspect ratio), that's a feature I'm planning for the coming weeks. I'm quite bugged by the PSP emulation on non xbox/ps3-like pads for now

                        Hello,
                        Don't worry, no pressure. The screen resolution is not a critical subject at all (at least for me).

                        Reading your message, I realize that I should have mentioned viewport/aspect ratio. You're right that's more like it : changing the ratio so that the game doesn't look "flattened" for instance, but the number of actual pixels in height or width actually remains. Just the pixels by themselves are stretched.
                        Thanks for the correction.

                        Sorry for using the wrong term earlier and good luck with your work the PSP emulation and non xbox/PS3 pads !

                          Sorry I had to resurrect this thread but it seems I had just created a thread about this same issue before realizing this one existed. I just wanted to reference this thread to my new one. Here is the new thread I created https://forum.recalbox.com/topic/17567/how-to-change-resolution-per-game.
                          It does seem that RecalBox is rather behind in-terms of useful settings compared to RetroPie.
