OpenBOR finally working fine on RETROPIE with ES

BiZzAr721

I'm the midst of all this exciting news I have a question (or 3).

Is .Pak the way it looks like we're going, moving forward?

Would that make emulation station boot up faster by not having to scan all those files in .bor directory?

Is there sacrafice for using .pak? (loading times - RAM issues)

cyperghost

@zanac found the patch you made

You forced videomode to case 0
Can you recompile with use case 255 instead? I think this will work, too and you change just one setting ;)

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

I think about using diff and patch tool so the git will be openbor main branch and patches are provided from here.

It's the BEST solution for sure :)
And the diff patch can be add to the Retropie Setup ;)

cyperghost

@darknior yes I think so. I just compared the changes from openbor C code. It is really a small patch. The second change was done to SDL section which I haven't checked so far.

So we will provide patches and do likely use archived openbor versions. But for the sake of using the main openbor branch I think it is worth to act like this. Advantage we can patch other things like CLI fir ex in those files.

darknior

@cyperghost Yes that's it :)
I love the idea
And the last version permit to recover Gamepads when they shut down, it is fantastic and will change our life lol
Like on RetroArch :p

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

zerojay

Are all these changes going to be available in source code form as well? I would like to have these running on my Odroid for instance.

cyperghost

@oilusionista as far ASD I checked there are hardcoded values for resolution. I did not check all the files but it seems just little modification.

cyperghost

@zerojay they are already available check the postings from @zanac

zanac

These days i cannot try make new patch suggested but my poc is public even source, just try all you want

+1 for this

Take your time I will step in the next days

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

Download archive @zanac with wget http://raw.githubusercontent.com/zanac/OpenPB4/master/openbor/openbor-engine-gl.tar.gz
Extract it with tar -xvzf openbor-engine-gl.tar.gz
EnterFile directory with cd engine-gl
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
make: *** [OpenBOR.elf] Error 1

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.

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