      @roslof what happens if you delete both ? this port uses ~/.emulationstation/es_temporaryinput.cfg if keymapv2.json is not present

        @myzar when I delete those files, then launch yabasanshiro-sh from /opt/retropie/emulators/yabasanshiro, it rebuilds the files, but not in a good way:

        keymapv2.json (all non-axis lines look like this):

        "id": -1
        "type": "",
        "value": "-999"

        Sega Rally Championship.chd.config everything references "null":

        "Aspect rate": null,
        "Resolution": null,
        "Rotate screen": null,
        "Rotate screen resolution": null,
        "Use compute shader": null

          I think I figured this out.

          I believe running from the command-line generates files at /root/.yabasanshiro/
          ...and running from runcommand generates files at ~/.yabasanshiro

          Was wrestling with two separate sets of configs...

          keymapv2.json in ~/.yabasanshiro was properly generated from es_temporaryinput.cfg
          keymapv2.json in root/.yabasanshiro is junk

          For game configuration files, both directories generate "null" for each setting. I suppose this is fine. Can use command-line arguments to set parameters.

            All set... Going to use these four (4) settings that consider RLE vs. real BIOS and original res vs. native res:

            yabasanshiro-sdl = "/opt/retropie/emulators/yabasanshiro/yabasanshiro-sdl -r 3 -i %ROM%"
            yabasanshiro-sdl-native-res = "/opt/retropie/emulators/yabasanshiro/yabasanshiro-sdl -r 0 -i %ROM%"
            yabasanshiro-sdl-saturn_bios = "/opt/retropie/emulators/yabasanshiro/yabasanshiro-sdl -b /home/pi/RetroPie/BIOS/saturn_bios.bin -r 3 -i %ROM%"
            yabasanshiro-sdl-saturn_bios-native-res = "/opt/retropie/emulators/yabasanshiro/yabasanshiro-sdl -b /home/pi/RetroPie/BIOS/saturn_bios.bin -r 0 -i %ROM%"

              Been playing around with the YabasueEmulate function. It's pretty much the core of the emulator. Anyone else here trying to improve performance?

              After moving some of the execution order around some it seems it doesn't matter if SH2Exec(MSH2 executes before or after the SSH2. If that is the case why aren't these threaded to run concurrently?

              I dug a little into them and I don't see any big hold ups. I suspect in some cases there may be a syncing issue but in those cases there is no work around anyway so who cares?

              I did some rough profiling and while running the intro of Sega Rally(used it for consistency) I saw about 10 to 20ms of processing time for the master and the slave(so 20 to 40ms total time per frame combined).

              I also checked the RPi cpu usage. Core 4 is pegged at 100% and cores 1 thru 3 average around 50% or less(using lowest graphics settings).

              Does anyone know any reason this absolutely cant be done? I'm planning on starting work on it unless I get a real good answer as to why it wont.

                @acidtech i think you should raise an issue at the github - devyimax is the only active developer: https://github.com/devmiyax/yabause/

                  fwiw, we tried this in the kronos emulator not long ago, on desktop there was no performance benefits, it was actually slower because of all the syncing.

                    @myzar Sorry for being dim, but how do you quit the Retro-Arena build without a keyboard?

                      @mechafatnick I'm awake, so jumping in.
                      The select button on the gamepad should be auto-mapped to the Yabasanshiro menu. Then you can select Quit.

                            Well, it's new, and it's for rpi0-3

                              Wow, just read this, thx for giving this information @barbudreadmon!
                              Well, i am no professional, but this sounds to me like a possible "turbocharger" for the Pi0-3.

                                that's hard to say, it would need proper testing, for software-rendered emulators the difference with gl should be marginal (assuming both drivers are of the same quality).

                                  Would a Vulkan rpi driver (either for pi3 or pi4) help emulation of 3D games (like psx, n64, dreamcast, etc.)?

                                    i am not too optimistic about that rpi 0-3 vulkan driver - since the hardware is not vulkan compliant, it will be missing many features, which is most likely to be a deal breaker for any 3d emulator with vulkan support

                                    the rpi4 vulkan driver may be more worthwhile, but it's WIP.

                                      @saccublenda Hard to say without proper testing, as mentioned by @dankcushions the driver doesn't seem to be fully compliant.

                                      Also, pcsx-rearmed doesn't have vulkan support (neither gl), you would need beetle-psx-hw for vulkan support (not sure if it's a viable option speed-wise or not, was it re-evaluated on rpi after getting its dynarecs ?)

                                        @barbudreadmon I was not referring to the rpi0-3 driver shown in the video, but to the official fully compliant Vulkan driver.

                                          @saccublenda well, you were mentioning both, and my answer remains the same for the official one (which might be fully compliant, or not)
