+1 for this

Take your time I will step in the next days

[cyperghost]

So here is a small How To to compile a bare OpenBOR v3.0 rev 6412
Tested with current RetroPie image v 4.4 (md5sum: 56988addb60361a2257a61c69d9fceac) on RPi 3B 1.2

We need following dependencies before
enter sudo apt install libsdl2-gfx-dev libvorbisidec-dev libvpx-dev

1. Download archive @zanac with wget http://raw.githubusercontent.com/zanac/OpenPB4/master/openbor/openbor-engine-gl.tar.gz
2. Extract it with tar -xvzf openbor-engine-gl.tar.gz
3. EnterFile directory with cd engine-gl
4. Now compile the whole thing make BUILD_PANDORA=1

To play:
Just put one PAK file into Paks folder. This will automatically start the single title. If you insert more PAKs into this, the selection menu will be displayed

Todo:

• Raise resolution
• Raise colordepth
• Make optionmenu according to RPi possibilites
• Debounce Joypad (can someone confirm?)
• Make sound louder
• ....

It's far away from complete but with enough manpower this thing will work.
Need some time for code review ;)

I probably will not be able to test until tomorrow evening, but I will as soon as possible!

EDIT
It failed on make with error:

Linking PANDORA Port: OpenBOR.elf...
/usr/bin/ld: /usr/lib/gcc/arm-linux-gnueabihf/6/../../../arm-linux-gnueabihf/libSDL2.a(SDL_rpimouse.o): undefined reference to symbol 'vc_dispmanx_element_remove'

collect2: error: ld returned 1 exit status
Makefile:661: recipe for target 'OpenBOR.elf' failed

I was using the image I was testing on - I uninstalled OpenBOR through RetroPie Menu then restarted before running commands. Sorry, I did not get a chance to retry. I also realized I wasn't logged in with root.

Tried again, this time with root and had an issue with dependencies. Tried apt --fix-broken install like it said and then when I ran sudo apt install libsdl2-gfx-dev libvorbisidec-dev libvpx-dev again I received

The following packages have unmet dependencies:
 libsdl2-gfx-dev : Depends: libsdl2-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Maybe I need to start from 100% clean image again

[cyperghost]

@bizzar721 I think you have used the libvpx file from @zanac opengl archive and put it to location libvpx.so.1 => /usr/lib/arm-linux-gnueabihf/vfp/neon/libvpx.so.1

please delete or rename that file and directory structure.
This lib is the last step before creating ELF file to binary.

[zanac]

One little problem that i encoutered on allwinner is that the GPU used is compatible only to GLES-2.0, and therefore openbor use OpenGL, this means that if i try to use hardware filters with GL it crash :(

With my solution openbor run in SDL and software filters and run very well... if in a future developers will implement a layer that wrap GL function to more then a backend (GL or GLES-2.0) we will be able to use also gpu hardware for bilinear filter!

[cyperghost]

@zanac Okay prepared a patch in unified format. There developers see your changes. Thank you for preparing this one. I hope that this will be the kick-off for new development.

This is Patchversion 1: Codename Анна

@cyperghost i tweaked the source again, today with gl4es lib and some small change i was able to make a version that run fullscreen with GL filters at full fps speed! Tomorrow i will try to share gl4es binary, openbor binary and a new source patched.. In My allwinner run much better dont know on rasbperry but i think that that Board is much similar.

[cyperghost]

@zanac I was able to compile old OpenBOR-3400 with full PAK and full load/save feature from the source you've provided I've also patched @darknior CLI patch in. So we have a full running OpenBOR maschine with working Video Menu, PAK support, load/save feature, highscore.
Maybe you can help out. All userdata is stored to homedirectory. Do you know a patch to locate those files next to binary? Working!! Watch out user rights!

You can download binary from my github account: https://github.com/crcerror/RetroPie-OpenBOR-scripts/tree/master/binary

• PAK support
• Highscore support
• load/save feature working

Everything is working!

ATTENTION UNSUPPORTED!!
Tagging @BiZzAr721 @darknior
Thx @zanac

[cyperghost]

@zanac I would be glad to test if you are ready.

The second change was done to SDL section which I haven't checked so far.

Can you explain what was done with SDL? I remember there was something wrong in some versions, I can't remember.

You can see the changes done to video.c in sdl directory ;) It is a hardcoded resolution posted here

I cannot use a pie, i run in an embedded board attached to jamma pinout.
https://en.m.wikipedia.org/wiki/Japan_Amusement_Machine_and_Marketing_Association

I use a jamma pandora box (search on web for info) that use allwinner chipset inside

Here you are a video of openbor run on jamma pandora inside My arcade cab (The boy is My son)

[BiZzAr721]

@darknior @cyperghost @zanac This is exciting - your baby is growing up so fast! ;p

[cyperghost]

@bizzar721 Well it is the excessive work from @zanac that makes this possible. With GL4ES much more things will happen with better speed and the OpenBOR Video Settings Menus should work as expected....
I just make some code reviews and compile a bit - far away from developing.

But here we come to a possible turning point. The Jamma Pandora BOX uses an Mali MP400 GPU... up to know we relied on working SDL framework and a similar CPU. This worked fine so far. If the binary with the GL4ES patch runs fine we can shake hands because then it should be possible to speedup the whole thing again, due better driver support for the Pie ;)

@zanac Watched some videos about the Jamma Pandora thing. Very interesting, it's a small PCB with JAMMA IO interface and the screen output is CRT with various frequencies for real RetroFeeling. The price for the box itself is not so much ... 60-80 USD. But I think the JAMMA things are not so cheap. All in all it seems very common to a Pie ;) So again ;)

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

:D

But here is a real "PANDORAS BOX" .... portable

About the gaming video you have posted... I have no FB account.

EDIT:
@darknior May you can take a look at the path thing of the OpenBOR PAK version? Source is here: https://github.com/zanac/OpenPB4/tree/master/openbor
I can't find out why directories are stored to UserPath and not next to binary.

EDIT 2:
Function getBasePath in /source/utils.c seem to be responsible for this.

Is working!

[zanac]

@cyperghost
here you find a binary... if it work in rpi i will upload the source package.

https://drive.google.com/open?id=1CphOM9RoniMhAaAsBeAbSnQUXn4WW8VH

It has inside libs used by OpenBOR, it refer some X11 libs but are not really used (gl4es link them but i forced framebuffer ;)) you must of course deploy the same but don't worry

the libGL.so is not open gl, is a compilation of gl4es, a wrapper that emulate open gl using gles2! Embedded boards, like rpi or allwinner, use gles2 and so we need this wrapper!

first to start OpenBOR insert in a script this line (if it work you can try other resolution, using gl4es you can force by this var the resolution!):
export LIBGL_FBOMAKECURRENT=384x224

If is the 6315 version that seems the most stable, if it will work i will share patched code of gl4es and openbor, i tested on allwinner as said is not the same actually, but if you're lucky.... ;)

If it will work you can go in video option, enable full screen, and switch from SDL to GL and use bilinear filter or so on using GPU!

Let me know, in allwinner this work very fine!

[cyperghost]

I'm out of buisness today maybe @darknior or @BiZzAr721 can test this for a quick run.
Watched your video.... that seems run very smooth now.

If gl4es don't work i just discover that in rpi it could be compiled with specific api for rpi driver...

from: https://github.com/ptitSeb/gl4es/blob/master/COMPILE.md
for the Raspberry Pi
cmake . -DBCMHOST=1; make GL

try anyway my binary, if it don't work i suggest you to recompile gl4es using that cmake string, after that edit src/gl/init.c and around line 34 change "#define DEFAULT_ES 1" with "#define DEFAULT_ES 2" after this just "make GL"

the bin created in this way should be usable on rpi if you "export LIBGL_FB=1" or "export LIBGL_FB=2".....

If you all works my OpenBOR binary should use GLES rpi driver, using gl4es wrapper

[cyperghost]

@darknior I changed some code from your sdlport.c, removed some checks ... this is really a fine work you've done.

	// Test command line argument to launch MOD
	int romArg = 0;
	if(argc == 2) {
		loadsettings();
		memcpy(packfile, argv[1], strlen(argv[1]));
		if(fileExists(packfile)) {
			romArg = 1;
		}
	}

I force usage of one argue (this makes sense) and check just presence of file
The rest makes ES

I just re-released the binary today. I don't want to share the old OpenBOR-code as it uses agressive words against OpenBOR developers. What a pity!

@zanac I've just downloaded the binary and started. It says libvpx.1 is missing. Didn't get deeper now .... lack of time now. The next patch will be Борис (Boris)
