      I found this...

      https://github.com/libretro/RetroArch/wiki/Compilation-guide-(Linux)#building-libretro-cores

      I'll start looking into it sometime soon.

        I would LOVE to see this, since so many of the games I have would look so much better.

        For one, in the GB version of Mighty Morphin Power Rangers (and MMPR: The Movie), only through Super Game Boy does the game give a character-specific palette, making the playable characters more distinctive. For example, when you play the Red Ranger, your sprite is red and as the Blue Ranger, your sprite is blue.

        Also, many games play much better, if not just sound and/or look better, in SGB mode.

        And iirc, many PC-based emulators (VisualBoy Advance) feature this.

          Anyone happen to know if I can just use the pre-compiled nightly binaries below?

          https://buildbot.libretro.com/nightly/linux/armhf/latest/

          I'm turning in for the night, but I got all the Bsnes cores listed there and tomorrow, unless I hear otherwise, I'll try the performance cores first. If they work out, I'll move on to accuracy.

            Well, I've been working on this off and on all day and it seems close to working, but I've hit a brick wall.

            My launch command is:

            /opt/retropie/emulators/retroarch/bin/retroarch -L /home/pi/custom-binaries/lr-bsnes/bsnes_performance_libretro.so --verbose --config /opt/retropie/configs/gb/retroarch.cfg /home/pi/custom-binaries/lr-bsnes/Super\ Game\ Boy\ \(World\)\ \(Rev\ 2\).sfc --subsystem sgb "/home/pi/RetroPie/roms/gb/Donkey Kong (JUE) (v1.1).zip"

            It begins to launch and it gets pretty far:

            The problem seems to be at the bottom where it has a segmentation fault and then exits:

            Without knowing more about what this really means, I'm at an impasse for now.

              Well, I'm satisfied now that this isn't going to work. I was finally able to get lr-bsnes-accuracy to reliably launch without crashing, only to be met with a black screen each time. After a little more research as to why this might be, I discovered that the Super GameBoy subsystem in RetroArch is simply broken on all Linux variants. What's more is that they've looked into it and have no idea why this is the case. So, unfortunately, Super GameBoy emulation is not happening on Raspberry RetroPie for the foreseeable future, but at least it won't be for a lack of trying.

                  Ha! That may be more correct than you know. Even if it had run, there's no guarantee that lr-bsnes-accuracy would have operated at more than a few frames per second on the Pi.

                      @mediamogul at least you tried something :D

                      I'm glad someone took a fresh look at it, it seems so complicated to create an inception of emulation :P

                      I mean there's a couple of gameboy games which are not emulated at their full potential since it's a really-hard-tu-pull-off project.

                        My hacked Wii runs an older version of VBA-M and emulates the Super GameBoy features very well. Support could even be found in lr-vba-next sometime before 2012. It seems to be an ability that's just falling between the cracks for the Pi at the moment. However, I'm sure the pieces will all come together again sometime in the future.

                          Any update on this? As @mediamogul mentioned, I tried several games on the latest VBA-M Windows build from Github (2e8bee1) and found most of them run well with SGB and SGB2 (unable to play arcade version of Space Invader though). Wonder if lr-vba-next will add back this feature.

                            @MisterXen Not sure, but i gave bsnes a try as well and ended up with the same black screen issue. still unclear to why since i don't receive the segment fault. Id assume it's probably a windows only feature or something rather.

                              The black screen and the segmentation fault aren't mutually exclusive. I was originally using an improper binary which lead to the fault. The libretro devs are also stumped as to the black screen, but with everything else on their plate, I don't think a lot of investigation has gone into it either.

                              Based on the linked conversation, their decision seemed pretty resolute. A little full color 'Donkey Kong '94' would be really nice.

                                I don't know if this is possible to add to retropie to try it out but I found a sgb emulator that possible could run on a rpi.

                                  I did some searching around and found this Youtube user that found a workaround to get Super Game Boy working in Retroarch on Launchbox. Perhaps we could adapt some of what he did to make it work in Retropie.

                                    Hi. Some news about this feature on PI ? Because the last video was on PC always with BSNES.

                                    Today Launchbox release some video preview : https://forums.launchbox-app.com/topic/42189-emumovies-nintendo-super-game-boy-videos-released-v10/

                                    I think we must use the border trick ... with this pack of 100 games : https://www.dropbox.com/s/s16grwhmcov0w2b/105 SGB Borders Retroarch Wii.rar

                                    The game list with borders is here : https://www.wikiwand.com/en/List_of_Super_Game_Boy_games

                                      The borders are a great addition, but man would I love to emulate the game's color palettes, especially 'Donkey Kong '94'. We're in good company though. Nintendo themselves didn't include the ability to access those palettes from the Gameboy Color when it was released. If they had, the various emulators could likely make use of the color by using the GBC BIOS rather than having to emulate a SNES to get the job done. There's also the outlying feature of 'Space Invaders' having an arcade port that is only accessible from the Super GameBoy, but aside from the novelty, there's a million different ways to play that game more authentically these days.

                                        @mediamogul Yes you are right, but i think it can be easier to use a GB emu with a trick to access this palette.
                                        It is not officially possible, but if SNES can, GBC emu can too.
                                        And if with border it make the trick it is almost perfect. Or maybe the GBC emu can show the border from rom too. And replace the Super Gameboy official menu.

                                          That would certainly be fantastic. What kills me is the feature is lying under the hood of VBA-M and even existed at one point in lr-vbam. However, it was intentionally removed by the libretro guys along the way, so it must have had some gremlins. As I remember, it could even do the borders.

                                            Is there a way we could get access to the old lr-vbam core? Maybe an old RetroPie release and extract the binary? I get that it might have caused trouble with GBA emulation but I'd stick to mGBA for that.
