OpenBOR finally working fine on RETROPIE with ES
-
@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 ... -
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/gl4esIn 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 2After this you should run cmake and compile:
cmake . -DBCMHOST=1
make GLFor use the lib i suggest this minimum environment variable:
export LIBGL_FB=2
export LIBGL_FBOMAKECURRENT=1OPENBOR, 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!!!

endifI 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 -O3The 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 Thank you for sticking around and seeing this through. It shows you take pride in your work.
-
@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 -
hi all just reading through this openbor section. im trying to get it working on pi3. ive got all my paks is there a tutorial on how to install it onto my pi thanks
-
@moonston333 Please use 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.

@cyperghost I will present Василий Patch next days for OpenBOR

@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 -

Thanksgl4es 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/scummvmAfter 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=4If 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 = ./liband create directory
libin OpenBOR dir and place libGL here -
@cyperghost This is Василий Patch
Changelog:
added lib next to binary
added cflags, change from O3 to O2Makefile

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
@darknior
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) -

Yes thanks a lot, if you can share it, i will try it :)

here you are:
https://drive.google.com/open?id=1iuV9BUN4g8-aaf9DAPrmxG0s3dn0RDoRFor 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.7zp.s. excuse me for the OT, this is not openbor stuff i know!
