        @darknior Maybe opengl4es will be able to benefit Residualvm as well


        Salvador Liébana was one of the devs who got Diable & others running on Pi

          @bizzar721 WOAW it's possible to play this game on PI ??????
          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

                    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

                    Using residualVM from the experimental section I am able to play

                    • Escape from Monkey Island
                    • Grim Fandango
                    • Myst 3

                    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:
                          https://github.com/zanac/OpenPB4/blob/master/retroarch/cores/scummvm_libretro/scummvm-games.7z

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

                                I think it can be a really good idea to share your work on an other thread to make every one using ScummVM on LR.
                                It is really excellent !!!

                                Same i wish it will be same in a few time with Daphne for LR too :)

                                  Sorry i have not time to follow a thread... anyway it's rather easy, i only tweak Makefile to add cortex/neon optimization on rasbperry, the source code of scummvm libretro work very weel on rpi/allwinner boards! :)

                                  I think it can be a really good idea to share your work on an other thread to make every one using ScummVM on LR.
                                  It is really excellent !!!

                                  Same i wish it will be same in a few time with Daphne for LR too :)

                                    Hello @zanac,

                                    I've collected all patch into a Openbor for Raspberry GIT ....
                                    We have patches: Anna, Boris, Wassili next patch will be Galina. I hope @darknior can make this work and we have CLI for PAKs ;)

                                      @cyperghost said in OpenBOR finally working fine on RETROPIE with ES:

                                      I hope @darknior can make this work and we have CLI for PAKs

                                      I don't understand ? You want i patch your OpenBOR version ?
                                      Why don't you had my patch directly ?

                                      Life is game, just play it !

                                        @darknior Lack of time ;) Just fork the repo
                                        Use patch -p0 -i patchfile.patch to patch and patch -p0 -R -i patchfile.patch to revert patches.

                                        So a working example would be patch -p0 -i ./patch/3-Wassili.diff

                                        Every patch is mode from original version. So patch #3 is the same version is I offer as download in openbor openbeta thread.

                                          Now that I got all my .bor back in .pak format, I tried the 3400 build and everything is working great.
                                          All we need is CLI patch and we're golden! @darknior

                                          I came across this post which lists a huge amount mods with version & compatable builds. It's pretty overwhelming the different amount of builds. It seems like build 4086 is very popular build.
