      @acidtech said in Raspberry Pi 4B 4GB and the Sega Saturn:

      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.

      I know the situation, actually i was the one who recommended to use standalone and to forget about the libretro core i wrote.
      With standalone version it will be significantly faster :

      • because you won't have to go through the libretro api for gl rendering, the most significant overhead you'll get with a libretro core over its standalone version is when opengl/gles is involved
      • because standalone version of yabasanshiro is offloading part of the rendering to a subthread, which is something impossible to do with the libretro api

        @barbudreadmon How do you go about installing the standalone core on the pi 4?

          @zering clone the pi4 branch with git clone https://github.com/devmiyax/yabause.git -b pi4 then follow the steps at https://github.com/devmiyax/yabause/tree/pi4/yabause/src/retro_arena#retropie-on-raspberry-pi-4 to build it ?

            @barbudreadmon Thanks. I've successfully cloned the branch but when I try the first cmake command I get a bash command not found error. Is it possible there's an error in the syntax?

              @zering i think that command line expects you to run https://github.com/devmiyax/yabause/tree/pi4/yabause/src/retro_arena#get-source-code first

                @barbudreadmon Thanks, I got it working. Very impressed with the results. Finally I can play Panzer Dragoon Saga again!

                  I followed the instructions to install standalone yabasanshiro for my Pi 4, and it's up and running. I tried a couple of games, and they work great! However I'm having one minor issue I'm hoping for help with. It says in the README that select is hard mapped to Show/Hide Menu, but even after mapping select manually through keymapv2.json in ~/.yabasanshiro, it's not recognizing select on my controller. I can only open the menu with Esc on a keyboard. Also, I need to use a mouse to navigate or interact with the Yabasanshiro menu. Is it possible to do this with just a controller? Sorry if this is a dumb question or one that has already been answered.

                    @zering I've done something wrong here.

                    Is this the order of code?

                    $ apt update 
                    $ apt install -y git python-pip cmake build-essential protobuf-compiler libprotobuf-dev libsecret-1-dev libssl-dev libsdl2-dev libboost-all-dev 
                    $ git clone https://github.com/devmiyax/yabause.git
                    $ cd yabause
                    $ git submodule update --init --recursive
                    $ mkdir build
                    $ cd build
                    
                    $ cmake ../yabause -DGIT_EXECUTABLE=/usr/bin/git -DYAB_PORTS=retro_arena -DYAB_WANT_DYNAREC_DEVMIYAX=ON -DYAB_WANT_ARM7=ON -DCMAKE_TOOLCHAIN_FILE=../yabause/src/retro_arena/pi4.cmake -DCMAKE_INSTALL_PREFIX=/opt/retropie/emulators/yabause/
                    $ make 
                    $ sudo make install
                    

                    I get all kinds of errors on the cmake line:

                    CMake Error at /usr/share/cmake-3.13/Modules/CMakeDetermineSystem.cmake:100 (message):
                      Could not find toolchain file: ../yabause/src/retro_arena/pi4.cmake
                    Call Stack (most recent call first):
                      CMakeLists.txt:1 (project)
                    
                    
                    CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
                    CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
                    CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
                    -- Configuring incomplete, errors occurred!
                    

                    It was going smoothly until then, I thought I was on to a winner!

                      @adambegood you need to add -b pi4 to the git clone command

                          @barbudreadmon Okay, thank you so much. I could have realised that, it was written elsewhere.

                          0abe4f28-2859-4afd-af42-87c2bf7d45b5-image.png

                          I've deleted the home/pi/yabause directory, but I still get

                          root@retropie:~# git clone https://github.com/devmiyax/yabause.git -b pi4       
                          fatal: destination path 'yabause' already exists and is not an empty directory.
                          

                          Any idea how I reset that? Thanks very much for the help.

                            I think this is dealt with previously, if you scroll up. It rings a massive bell to me.

                                Judging by the root@retropie:~# prompt, you aren't in /home/pi folder, you are in /root folder, and you probably have a /root/yabause folder.

                                    Are you 100% sure you are logged in as root? I am pretty sure it would say root@retropie if you were, and those errors look like you're not also..

                                            Okay, have a Google of logging on as Root.

                                            You should be logging on as Root and password, but there is some small set-up you need to do first.
