      @darknior There is space to optimize. This now runs with SDL but with the right wrapper settings in GL4ES it is maybe possible to select OpenGL.

        @cyperghost Like you i think we must have the two versions of OpenBOR on PI :(
        Like they do on PC with many Windows version for each games ...

        I must use 3400 for

        • Asterix & Obelix
        • Bare Knucles 6 (but it crash some time...)
        Function getentityproperty must have a string property name.
        Script function 'getentityproperty' returned an exception, check the manual for details.
        
        • Bare Knucles Vacum v4.1 (but crash during loading of a script) :(

        All the new games working fine with the last version ...
        I will try to find time to test each game one by one ...

        We will always have this problem with some games, made with a specific OpenBOR version we don't have on PI ... :(
        Or maybe we can find some one who can help to fix games for the old or the new version.

        Life is game, just play it !

          @darknior We can compile older sources, too. Maybe 43xx branch. I am sure we can do the same changes here - did not test now.

            @cyperghost Yes, thanks, i think you are right et we must have some other OpenBOR versions like the 43xx too.
            It was the problem of OpenBOR from the beginning, it evolve but there is no retro compatibility with games :(
            Or the games don't write for what number version they are created ...

            Life is game, just play it !

              As i promised.... here you are what i done, sorry i have not too much time to write all in a clear way but i'm sure that you will understand reading... if in doubt just ask!

              GL4ES, just try my fork:
              https://github.com/zanac/gl4es

              In CMakeLists.txt added:
              set(NOX11 ON)
              set(NOEGL ON)
              add_definitions(-marm -mcpu=cortex-a9 -mfpu=neon -mfloat-abi=hard -ffast-math -fomit-frame-pointer)

              the NOX11 and NOEGL should be tested, i added these lines last weekend and have just seen that in allwinner board work better ('cause with these i removed some dependencies if you use GL with framebuffer)

              In src/gl/init.c
              I changed defualt to ES 2.0:
              #define DEFAULT_ES 2

              After this you should run cmake and compile:

              cmake . -DBCMHOST=1
              make GL

              For use the lib i suggest this minimum environment variable:
              export LIBGL_FB=2
              export LIBGL_FBOMAKECURRENT=1

              OPENBOR, i don't make a fork, but it's rather easy to patch the build_pandora, if you have time just create a new build_rasbperry with these tricks!!!

              ifdef BUILD_PANDORA
              TARGET = $(VERSION_NAME).elf
              TARGET_FINAL = $(VERSION_NAME)
              TARGET_PLATFORM = PANDORA
              BUILD_OPENGL = 1
              BUILD_WEBM = 1
              BUILD_LINUX = 1
              BUILD_SDL = 1
              BUILD_GFX = 1
              BUILD_PTHREAD = 1
              BUILD_SDL_IO = 1
              BUILD_TREMOR = 1
              BUILDING = 1
              CC = gcc
              INCLUDES = $(PNDDEV)/include
              $(PNDDEV)/include/SDL
              OBJTYPE = elf
              LIBRARIES = $(PNDDEV)/lib
              ifeq ($(BUILD_PANDORA), 0)
              BUILD_DEBUG = 1
              endif
              endif

              I also patched CFLAGS for arm optimization:

              CFLAGS += $(addprefix -I", $(addsuffix ", $(INCS))) $(ARCHFLAGS) -D$(TARGET_PLATFORM)
              CFLAGS += -g -Wall -Werror -fsigned-char -std=gnu99
              CFLAGS += -marm -mcpu=cortex-a9 -mfpu=neon -mfloat-abi=hard -fomit-frame-pointer -ffast-math -O3

              The lib should link GL:

              LIBS += -Wl,-rpath,$(LIBRARIES) -lSDL2 -lSDL2_gfx -lGL

              The only source that i bad patched now is opengl.c:

              in sdl/opengl.c

              I made these changes:
              // create an OpenGL compatibility context, not a core or ES context
              #ifndef WIN // except on Windows, where some Nvidia drivers really don't like us doing this
              //zanac, these attributes don't work well in allwinner (rasbperry too?)
              //SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_COMPATIBILITY);
              #endif

                  //zanac, it seems that you should always create a new context without delete the old one, this happen in allwinner (rasbperry too?)
                  //if((context = SDL_GL_GetCurrentContext()))
                  //      SDL_GL_DeleteContext(context);

                  @zanac Can you please post in a better format? I wasn't able to compile and catched one error...

                  Please use three backticks ``` in beginning and ending of codeblocks to get proper format ;)

                  OKAY GOT IT

                  Please remove LIBS provided from @zanac first build from lib directory....
                  Use the install instructions done here

                      Please remove the binaries provided in the google download if you want to compile on your own.... you will catch errors.

                      We are still work in progress.

                            We can also maybe play to "Return to the future" ???
                            Incredible, maybe it can help yes, if you have some informations, create an other discussion please and give the link here, i'm very interested, i'm a BIG fan of ScummVM too :p
                            Thanks

                            Life is game, just play it !

                              gl4es is just a wrapper that translate some "open gl" function to "open gl es 2", if you want to play 3d games you need that software use "open gl es 2" (gles2 for friends) natively!

                              About scummvm.... as i said it is possible to run it under libretro core, so it use gles2 natively using retroarch!!!
                              Just download: https://github.com/libretro/scummvm

                              After this just go to the folder "backends/platform/libretro/build" and type "make -j 4" :) It will compile (in about 7-8 hours!!!) a working core for allwinner/rasbperry!!!

                              For improve scummvm speed i suggest to hack the makefile and use neon+arm+cortex optimization... i use these:
                              TOOLSET = arm-linux-gnueabihf-
                              TARGET := $(TARGET_NAME)libretro.so
                              SHARED := -shared -Wl,--no-undefined
                              DEFINES += -fPIC -Wno-multichar -D_ARM_ASSEM

                              LDFLAGS += -shared -Wl,--version-script=../link.T -fPIC
                              CC = gcc
                              USE_VORBIS = 0
                              USE_THEORADEC = 0
                              USE_TREMOR = 1
                              HAVE_MT32EMU = 0
                              DEFINES += -marm -mcpu=cortex-a9 -marm -mcpu=cortex-a9 -mfpu=neon -mfloat-abi=hard -ffast-math -fomit-frame-pointer -O3
                              DEFINES += -mfloat-abi=hard
                              DEFINES += -DARM
                              HAVE_NEON = 1
                              DEFINES += -DSIZEOF_SIZE_T=4

                              If you want i can share the libretro_scummv.so core compiled in this way, it work very well i use it and is very great!!!

                                new hint.... it seems that is better use -O2 for compile openbor!!!
                                just replace in makefile patch that i mae O3 with O2 : )

                                  @zanac I would suggest to use sperate libGL for each game.

                                  add Makefile

                                  LIBRARIES       = ./lib
                                  

                                  and create directory lib in OpenBOR dir and place libGL here

                                      If you want i can share the libretro_scummv.so core compiled in this way, it work very well i use it and is very great!!!

                                      I would love for you to share the libretro_scummv.so core. Although eventually, learning how to compile is something I want to learn how to do. Thanks

                                      The pi takes a big hit running them, but they are playable
                                      ResidualVM itself still has bugs

                                        @bizzar721 Compiling we do here is provided by scripts. Makefile or CMakeList for example. These scripts tell the compiler the order of source files and on which mashine they build. So it's not really difficult to do... Sometimes programmes give hints which compiler flag do this and that.... also not difficult to implent (a bit more know how needed)

                                        The stuff @zanac and @darknior have done is really advanced. You must understand how the code works and analyse options. For example @darknior patch makes use of function fileExists. You may think it's an ususal C-command, no... it's a functions that is nested into /source/utils.c. (A very common way to do check file availability... but other languages provide a command for this)

                                            here you are:
                                            https://drive.google.com/open?id=1iuV9BUN4g8-aaf9DAPrmxG0s3dn0RDoR

                                            For use in a game... i try to make an example. For example i have "Full Throttle" adventure, inside the game folder i place a "Full Throttle.scummvm" file, inside it you must just insert the "logical scummvm name", that is in this example "ft"

                                            Here you can find a sort of "database" of scummvm files:

                                            p.s. excuse me for the OT, this is not openbor stuff i know!
