      @sergioad I think it is not in the retropie setup because it is unfinished and someone other than the developer has used a patch to get it working. I have now managed to get it to install by copying and pasting the files from here: https://github.com/joolswills/RetroPie-Setup/tree/lr-yabasanshiro/scriptmodules/libretrocores and placing them in the directory /home/pi/RetroPie-Setup/scriptmodules/libretrocores/. The diff file needs to be in a folder called lr-yabasanshiro. Make sure you save them with the correct .sh and .diff extensions. I know this is a clumsy way to do things but I have not really got to grips with git yet and this worked for me.

        @t1moth I think I will wait, although being able to play SFZ2, NW, MM8, MvS, XvS and other cool 2D games on their ultimate form is enticing

          @sergioad alot of reasons its not on the list and
          , It is not ready for noob users, issue it has is the graphics get scrambled in random, crashes in few games, not all games run at full speed some 3d do like battle arena toshinden remix from what i have tested it runs great but with vsync off so things are reversed or damaged, this is just some reasons but once you install it runs most games great, with newer updates to mesa some games i had are now broke like die hard arcade and some run better, i did play dracula x the whole game thru out the castle and plays perfect no glitches, only glitch i did see is in the water cave where the fish dudes come out.

          Most games do run great and enjoyable but games like virtual cop 1 or 2 run slow, you can play export and it runs faster not sure if it speeds up yo make the game harder or what.

          I have tired alot of imports most worked but games like xmen vs street fighter no go crashes and runs super slow.

          Id say it is enjoyable and playable on rpi4 with no overclocking

          Stay away from Doom has alot of glitches and bugs so no go and besides its not the best port.

          But This is mainly why i bought the pi4 for this castlevania on saturn and runs at full speed.

          A list of games that run
          Dracula x
          Batman forever
          Battlemonsters
          Battle arena tosihden remix
          Elevator action 2
          Darious gaiden
          Golden axe the duel
          Daytona usa 45fps to 60 so not bad music does skip
          Shinobi
          Magic carpet
          Marvel super heroes
          Mass destruction
          Street fighter collection
          Street fighter the movie
          Street fighter alpha 1 and 2
          War craft 2
          Mortal kombat trilogy
          King of fighters 96
          Bomberman
          Clock work knight 1 and 2
          Contra legacy war
          Hercs adventure
          Ironman manowar
          Legend of oasis
          Rampage world tour
          Umk3
          Raident slivergun
          Alien trilogy
          Astal
          Coton 2
          Crypt killer
          Three dirty dwarfs
          Tomb rider

          This mostly why its not on the list but retropie needs a some what work friendly emulator for the community im sure once some things pick it will run most games at full speed in time will tell.

          To install try to find a how to or im sure someone can help i could never get it going since i had my own version fixed around the same time buzz and retropie team fix there version.

            @notthesame thank you very much, as I said I will wait as I am not that advanced, how does Marvel Super Heroes Vs Street Fighter or Night Warriors work? When the issues get fixed and I could get it from the script if both of them work I would be set to play a little bit of Saturn :)

              how does Marvel Super Heroes Vs Street Fighter or Night Warriors work

              Just making this clear because there is a tendency of people exagerating the "good" state of saturn emulation on pi4 :

              • i didn't hear of a single game that run full speed on pi4 if you disable the auto-frameskipping, meaning some games might run "full speed", but that's at the cost of non-smooth animation since they won't render every frames
              • expect 3 frames of input lag as the best case scenario, i've seen some of those games going up to 7 frames of input lag
              • lots of those games are arcade games already available on mame/fbneo, with far lesser input lag (sometimes down to 0 with runahead), no frameskip, and no known glitch. another part of those games is available on psx, in a far better state of emulation too.

              All of this to say : "Marvel Super Heroes Vs Street Fighter" and "Night Warriors" are perfect examples of games you should never even think of playing on yabasanshiro.

                @barbudreadmon got it, thank you very much, sadly neither got a port to the Capcom CPS Changer with practice mode included, if they did I would pick them there instead of the inferior PS1 ports because I like fighting games for the training mode

                  @sergioad you could probably make something similar to a "training mode" by using cheats

                      i'm never too sure what people like about those training/practice mode, but if it's only about having infinite everything to go all out, i know pretty much any fighting game has cheats to allow that, using cheats might be less convenient than having a practice mode though, idk.

                        @barbudreadmon it is not only having everything, but having an inmobile punching bag and being able to swap characters on the fly

                          Here's an appropriate challenge (skip to 37:45)

                          SEGA Rally Championship was one of the bottleneck titles of the system. If you can get it to run on a Pi, you can automatically run anything.

                          I think the issue is that nobody made any special Dynamic Re-compilers for any of the Emulators. Saturn Emulation has always been heavily CPU reliant.

                            You are wrong though.

                            This video is the perfect illustration of how bad sega saturn emulation is on pi4 despite the fps counter sometimes being close to 60, it's crazy how high the auto-frameskipping gets, i'm wondering how many frames it actually shows out of those nearly 60, feels more like using microsoft powerpoint at this point, it's almost hilarious in street fighter alpha 2 (one of the saturn 2D games reported as "being perfectly playable" on pi4 ?) when the flickering fireballs sometimes won't even be visible due to all the visibility frames being skipped.

                              yabause has had an sh2 dynarec forever.

                                Yeah, furthermore the bottleneck for saturn emulation has always clearly been the rendering part with its 2 VDPs. Pi4's GPU is just way too lacking to handle that...

                                  @barbudreadmon So, being realistic, we can't expect Saturn emulation to improve until the next generation of Pi computers?

                                    @zering I suspect a big part of the problem to be in pi's GPU drivers, but yeah having a superior GPU (assuming pi5 will have that) would certainly help. Otherwise you could also consider buying a better SoC, like the odroid n2 which was available long before the pi4.

                                        Have only test Night Warriors ... runs pretty good using lr-yabause with no frame skipping on :)

                                          One of those statements is false.
                                          Just to be clear, the fireballs must flicker, they do in all 2D street fighters afaik, flickering was an effect used to fake transparency before 3D systems, it is about showing an element for 1 frame then not showing it in the next one, and repeat.
                                          If your fireballs don't flicker, then that means the frames when the fireball is invisible are skipped, and you have frameskip on.

                                            @barbudreadmon Sorry, but that video was horrible. I compiled a version of Yabause/Sanshiro last year/early this year and played Sega Rally significantly better than that and that was just a goof to see what was could be done.

                                            see link below.

                                            So don't get too down based on that video.

                                            Found the old thread: https://retropie.org.uk/forum/topic/24568/is-yabasanshiro-emulator-coming-on-retropie/268?_=1613102464587

                                            Follow the instructions there(you will have to piece them together somewhat but its not that hard) and you should be able to build a standalone yabause/yaba sanshiro that plays sega rally decently. Not completely without frame skip but way better than that video shows.
