OpenBOR finally working fine on RETROPIE with ES

@darknior
An italian friend that is hacking like me on Pandora Jamma Box [*] has made a bad patch for enable saving! Keep the source patched here:
https://drive.google.com/open?id=1ktoFqLj2Do6RHyeEdqffKsQOunb7c2Wz

[*] Actually we are not using RPI but a different chipset but that has ARMHF, anyway it's not difficult to make compile latest version of openbor, but it is very slow trust me! :( What kind of problems did you have compiling? I think that is much better use this very old version but at least it is fast!

zanac

Here you can find a version that seems better, it use pak...

https://github.com/rofl0r/openbor/releases/tag/compatible-official-3400%2B

For compile it just remove Werror from Makefile (i remove also BUILD_OPENGL and BUILD_LOADGL on pandora actually), it seems support also save game!

darknior

@zanac Thanks a lot for this fix, i wish some one will add it to my git with issues system.
For the moment i can't do it myself :(

I understand the last version is slow, but it is strange because it's the same engine. Nothing more than new script functions.
And the last mods use them ... and are fantastic for sure !!!
I wish one day it will be possible to use the last version on pi :D

@darknior @zanac I am in journey. Can't do anything at the moment. But I think there are great leaps made

zanac

I think that new version is slow for SDL2.0 usage.... I compiled the new one using:
make BUILD_PANDORA=1 -j 3

I don't know if it's slow also on rpi, as i said i use allwinner chipset that for rendering use a mali-mp400, maybe the video card of rpi work better!
Just try to compile by yourself using that command... and of course install sdl-2.0-dev headers: trust me it compile fine and run!

@zanac Thank you. Can you share the binary? I think this would speedup progress.

AFAIK the GPU of the Pie is not very powerful ... Sorry I can not test yet

For speeding up SDL2

zanac

here you are two binary, but i compiled with cortex-a9 (for allwinner), if it don't run i must recompile for generic arm... let me know! The first one is without GL, the second with GL, try both!

@zanac Thank you
Here are some SDL2 prebuilds with stripped down dependencies. This should speedup

Sorry, i cannot use sdl prebuilds for rpi, i must use patched version of libsdl2 for mali... ;)
i already patched sdl2 with this patch https://github.com/recalbox/recalbox-buildroot/blob/master/board/recalbox/xu4/patches/sdl2/sdl2-0003-mali.patch

but this is another story, i don't use rpi as i said ;)

cyperghost

@zanac I think RetroPie is installed by default with SDL2 maybe some admin @mediamogul can confirm?

So indeed if someone will rebuild OpenBOR chances are high for a good speedup

Yes but if you are Lucky bin that i linked work also in Your rasb! Just try

zanac

I can officialy confirm that GL version using SDL-2 patched is very fast!!!
So you can just use a GL version on RPI and you will enjoy a new version of openbor also o RPI!!!

cyperghost

@zanac you made my day. How did you patch SDL? And which rev number is the openbor engine now?

I built 6412!
I attached the binary some post ago, Just try it, you dont need to patch sdl2 on retropie, i had to patch sdl2 cause i use the mali gpu as i said.
Maybe the only thing needed for rasb is the sdl2gfx lib..
I m sure that also on rasb is possible to make it work like on allwinner Board, trust me! We have arm both and very similar chipset.

@zanac This is great news. Thank you!

cyperghost

@bizzar721 @darknior Seems to be your turn .... I'm still on journeyh

I quickly created & setup a new image, installed OpenBOR from retropie setup. I switched out the Binaries & set permissions to 0755. It wouldn't load. Just goes back to ES. I'm sure it's something simple but that's beyond my skill.

cyperghost

@bizzar721 Can you post output of runcommand log?

please try this
sudo apt-get install -y libsdl-gfx1.2-5

This is the sdl-gfx for Rpi fixed

After that you can try to install SDL2 as @zanac mentioned with
sudo apt-get install libsdl2-dev

BiZzAr721

I will do. Are you saying this binary is compiled to accept launching command (as in how it's currently set up)? Or should I use the "vanilla" openbor I set up? I also tested with .PAK and .bor folders.

EDIT
Using OpenBOR with game selection script here is the runcommand log:

Parameters: 
Executing: pushd /opt/retropie/ports/openbor; /opt/retropie/ports/openbor/OpenBOR "/home/pi/RetroPie/roms/ports/openbor/Battletoads & Double Dragon IV - The Return of the Dark Forces.bor"; popd
/opt/retropie/ports/openbor ~/RetroPie/roms/ports/openbor
/opt/retropie/ports/openbor/OpenBOR: error while loading shared libraries: libSDL2_gfx-1.0.so.0: cannot open shared object file: No such file or directory
~/RetroPie/roms/ports/openbor

cyperghost

@bizzar721 I assume this binary is vanilla. So it will accept PAKs only via its own launching menu. But if the menu is up it will run every game. The CLI can be patched later. I think it would help if you post content of error log.

If you have used the first fix you can try to run the pikiss openbor binary, too
I have saved it for later use. It is downloadable from here

https://github.com/crcerror/RetroPie-OpenBOR-scripts/tree/master/binary

You can also Google for pikiss openbor then you see the install script which installs sdlgfx fix
