      Sega Saturn is one of the most difficult hardware to emulate, it’s 2 cpus and 8 different processors, in my opinion, nothing different from a traditional PC, x86 architecture will be able to run satisfactorily.

        @wmarcio Panzer Dragoon Zwei does run okay on my Pi, and 2d stuff is fine. Nights is not happening though.

          @AdamBeGood You have two options for saturn right now but first you have to overclock to at least ~2Ghz and v3d to ~750Mhz.
          Go to this thread: https://retropie.org.uk/forum/topic/24568/is-yabasanshiro-emulator-coming-on-retropie

          1. Get the lr-yabasanchiro build script that's not done and throw it in to your retropie-setup folder and then go install it. Some 2d games are full speed. Panzer Dragoon 1 is around 45-55fps without frameskip and no crt shader. ~60fps with auto frameskip. Sega rally is around 30-40fps.

          2. Get the desktop installed then install one of the binaries from that thread and run it that way. It's around 10fps faster than the libretro version. No idea if anyone got it properly built for retropie.

          Overall, it has visual bugs and in some games it's so much that I don't recommend playing those games like Panzer Dragoon 1. Seems to be a problem with the pi4 mesa drivers that has no fix yet. Both versions of this emulator don't have the problem of getting scratchy audio if it hits below 60fps.

            @Darksavior Option 2 sounds a bit involved to me, so I'll try Option 1. The thread is vast, is the link to lr-yabasanchiro within that? I am trying to read through it but there is so much of it. Could you just confirm it is in there somewhere, and isn't just something I should be Googling? Thank you!

              @AdamBeGood it's located here https://github.com/RetroPie/RetroPie-Setup/pull/3132

              Edit: don't forget the shader hack/patch as well

                @quicksilver I don't even understand how to get the files here, so this might be a lost cause for you. Feel free to duck out of helping!

                Do I take the text from within the section I've screenshotted, and save the files as they are titled in the top line? Then put that in the folder you suggest, and then my Pi will see it and be able to do the install?

                I'm sorry for being poor, I am trying to suss it out.

                  @AdamBeGood ill make it easy on you. :)

                  https://mega.nz/folder/sZRGkQQD#TYvZ3m7WxwuN2zlf4VjPrg

                  I have attached a link for the install script and shader hack. Place both the lr-yabasanshiro.sh script and the lr-yabasanshiro folder in /home/pi/RetroPie-Setup/scriptmodules/libretrocores/Then once they are in place you will be able to install it from the experimental modules section of retropie setup.

                    Amazing! I find mega.nz temperamental both on my PC and phone, quite often nothing happens when I click on links (and that is the case here). Eventually I will get in though, and I will try this then! Thank you very very much.

                    On Chrome and IE, I get this with Mega.nz. I get nothing on my phone browsers.

                      @quicksilver Works an absolute treat! Sound seems slightly on the quiet side in some games (Daytona for one), but compared to the stock emulators it is streets ahead. Nights Into Dreams is playable!

                      Thank you! Really, this is great. I don't understand why it isn't on RetroPie by default, the cores that are included are certainly no better!

                        because you are running an unaccepted fix - we're waiting for the lead developer to have a look into this issue. once it's resolved the core could be added.

                          @dankcushions Oh I see. Well, it seems to be running pretty well anyway, hopefully it will be available to people who don't have your help soon! Thanks again.

                            @quicksilver I have seen glitches with the emulator now. Alien Trilogy goes a bit mad sometimes, but usually comes back before too long. I also saw this on Slam 'n Jam 96. Most games have been perfect though.

                            Oh, and there are no sound effects in PowerSlave. Alien Trilogy really isn't playable, I've persisted with that a bit now. Slam 'n Jam is playable, despite seeing glitches occasionally.

                              Just wanted to say thanks to quicksilver for posting the script to get it running.

                                @Krakatoa I just reposted it. I claim no credit for the script or the shader fix. All credit to BuZz and anyone else that was involved in getting it working.

                                  @quicksilver I've installed it thanks to your guide. Can't get games to start though.

                                  Does anyone know the accepted format for the emu? Tried a few but no joy.

                                  Also added some bios but that doesn't seem to work...

                                    @Jste84 I've been using .bin and .cue, that has been fine. Maybe keep trying with the bios, possibly you've had duff ones.

                                      @quicksilver Any idea on the missing Sound Effects on PowerSlave? Are there any settings that might make this work? I guess I could have a dodgy ROM, I am only assuming the fault is with the emulator here.

                                        @AdamBeGood the emulator is far from perfect. In fact I have encountered issues with most games I tested. You can try enabling/disabling the HLE bios option in the retroarch quick menu. Sometimes it has a positive effect for some games.

                                          @quicksilver Okay, cool. I'll try that out then. It is such a fast emulator though, games are so smooth (when they work).

                                            @AdamBeGood was making a daft mistake in not renaming the bios. 😣
