      @Darksavior @buzz I'm still learning with building packages. I'm not sure what needs to change in lr-yabasanshiro.sh to make it use your branch. Currently the default is as follows:

      gitPullOrClone "$md_build" https://github.com/libretro/yabause.git yabasanshiro

      What would I need to change in this?

        @firebird_ws6 what do you mean default?

        The code is not in RetroPie by default and that line has been changed in my branch some time ago.

          @buzz I meant the files that quicksilver posted earlier in this thread. I'm still learning with Github, I think I found your branch (as opposed to your fork), which it looks like was updated just now. I copied the code into the files on my Pi4 so I'll give it a go at building again. Thanks for your help.

              @firebird_ws6 nothing changed in the branch. I just rebased it so it contains recent retropie changes from master branch. You need to checkout my branch and build from there.

              You can do this in another location. Maybe Google how to clone a Pull Request on GitHub. I think GitHub provides info on this also on the Pull request.

              eg. To grab a copy of this branch.

              cd ~
              mkdir temp
              cd temp
              git clone -b lr-yabasanshiro https://github.com/joolswills/RetroPie-Setup.git
              cd RetroPie-Setup
              sudo ./retropie_packages.sh lr-yabasanshiro
              

              If I update or rebase you can remove and redo or do git fetch origin and git reset --hard origin/lr-yabasanshiro

                @buzz @Darksavior Thanks again, that worked! It's installed and working.

                  @firebird_ws6 Did yours work using Quicksilver's patch? I've entered the code that Buzz gave above:

                  cd ~
                  mkdir temp
                  cd temp
                  git clone -b lr-yabasanshiro https://github.com/joolswills/RetroPie-Setup.git
                  cd RetroPie-Setup
                  sudo ./retropie_packages.sh lr-yabasanshiro
                  

                  That all seemed to work fine but I am still getting the message that the shader hack has failed to apply when I update lr-yabanshiro, so I wonder if I need to do anything with that patch - or if the above would have updated that also...

                  Edit: I've tried replacing Quicksilver's Patch file with Buzz's, but the result is the same.

                    @adambegood No change. Since Thunderforce 5 runs at around 35fps on my pi4 at 2Ghz/750Mhz, I don't expect to ever be playable.

                    This probably sounds mental but mine is running at 50 FPS consistently on yabasanshiro, I've played a little bit of the game now. This is with the patch not applying. I've found that Radiant Silvergun is totally unplayable now but most games are fine. There is some tiny glitching on ThunderForce but nothing major.

                      @adambegood Radiant Silvergun runs reasonably well on yabause, as does Guardian Heroes. Both run better on yabause than on yabasanshiro.

                        Yeah I've found Yabause is fine for Radiant Silvergun, but thank you. Currently between the two emulators, most stuff seems to work even if I don't have Yabasanshiro properly patched. Night into Dreams and Panzer Dragoon 2 seems to run decently also, it is only Radiant which is really banjaxed by not having the patch.

                          @adambegood Night into dreams is a choppy mess for me, panzer dragoon 1 and saga are unplayable. Not sure if I have the patch.

                              @adambegood Yes. It's an impressive emulator.

                                Weird .. how can it be so different for me? I haven't played much into Nights to be fair, but it seems fine initially at least (40-45 FPS). I've heard there are problems with Panzer 1 and that emulator. Saga seems okay to me, but I've only just started it up really so I can't vouch for it.

                                  @adambegood Saga is frustrating. The pre rendered cutscenes are perfect. Then you get into the gameplay and it's choppy as hell and the sound is garbled and horrible. Panzer dragoon has graphical glitches that make it unplayable but Zwei is considerably better anyways. I've seen other games with serious graphical issues. Dark saviour has no image or garbled graphics. Enemy zero has perfect cutscenes but no video during gameplay. Deep fear is... I'm not sure how to describe what's going on with Deep fear.

                                  Problem is so far I haven't been able to determine how much the issues I'm seeing are exclusive to my rig or if it's simply due to the experimental nature of the module.

                                    I might give those games a go to see what happens on mine then. I don't think I've heard of any of them.

                                    Edit: Tried Dark Saviour, also v broken on mine.

                                      Considering saturn's VDP1 (the heaviest component to emulate, actually one of the first nvidia gpus, responsible for rendering 3D) is most likely idle when playing CGs, it makes sense.

                                          I noticed you have Kronos listed in your signature. How is that going? Any idea if we might see it in RetroPie?

                                            @adambegood it’s already in retropie: https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/libretrocores/lr-kronos.sh

                                            but only for x86 as the system requirements are to steep for ARM
