      @substring said in NEW Reicast Cores in RA:

      Why do they diverge that much from upstream ?

      Well, that's definitely not on purpose, from what i can tell, arm/x86/x86_64 dynarecs in standalone reicast are really different, i guess the x86_64 one was easy to get working in the libretro port, while the 2 others weren't. Actually, i looked at recent commits and it seems twinaphex is still trying to fix the arm one.

      Libretro developper :

      • FBAlpha FBNeo (Arcade)
      • Kronos (Sega Saturn/ST-V)
      • YabaSanshiro (Sega Saturn)
      • Reicast Flycast (Dreamcast/Naomi/AtomisWave)

        @substring You can find the "standalone version" of reicast-oit there : https://github.com/flyinghead/reicast-emulator
        This one got the dynarec and multithread support, but you still need opengl 4.3 (perhaps it also works with gles3).

          @barbudreadmon yup, found the repo while browding through TA's commits on reicast OIT. Will give it a try after summer unless someone else in the tea wants to have fun with it

            Hi @substring and others.
            The master branch of my reicast fork should work fine on a Pi. I tested it and made sure to keep performance to an acceptable level. It adds a number of features compared to upstream reicast: shadow volumes, clipping, render to texture, multipass rendering support and a number of bug fixes.
            The OIT branch (fh/deferred-shading) on the other hand is very experimental and require desktop-level cpu and gpu (and OpenGL 4.3). It also only works with NVIDIA gpu at the moment and has a couple of bugs, but I intend to improve this in the coming weeks.

              @flyinghead Hey ! Welcome on board, glad to see you here 🙂

              how does your reicast fork work compared to skmp's in terms of performance ? like ... does the date finally get saved ? We've also spotted a bug of improper exit of reicast with some dirty die here and there, not cleanly deinit-ing SDL2 which can cause some problems on some boards using GBM rather than FBDEV.

                Performance should be similar to skmp reicast although most features I added do have a slight performance hit.
                I also integrated fixes for clean exit, so that the date and VMU are properly saved on exit.

                  @flyinghead That's impressive work !
                  Does Shenmue 2 run on pi3 now ? It's stop after the end of the introduction.
                  It's great to see that there is a hope of seeing improvement with DC emulator on pi 🙂

                      @gaetan I believe the problem with Shenmie 2 is that it has self-modifying code, which breaks the recompiler. I haven’t made any change is this area unfortunately.

                        @flyinghead Ok. Thank you for your work !
                        DC is a great system and it's nice to see people involved in such a project 🙂

                            @flyinghead est-ce que tu sais si sur ton fork les jeux Worms fonctionnent ?
                            Avec la version actuelle il y a un retour à la gamelist systématique quelque soit le format de la rom.

                              @gaetan Malheureusement, non. Les jeux Worms utilisent Windows CE, qui n'est pas supporté pour le moment.

                                @Flyinghead ok, j'avais beaucoup joué à cette version du jeu à l'époque 🙂
