OpenBOR finally working fine on RETROPIE with ES

darknior

@zanac Thanks a lot, really :D
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 :)

zanac

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! :)

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 ;)

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

cyperghost

@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.

cyperghost

@bizzar721 Thanks for this list. I am still on business and have no time for do anything for open or ;( So I hope @darknior can help ;)

Thanks a lot for this list, for sure it can help a lot, i don't have the OpenBOR version of all my mods :p
Like that now we know if one mod not working, what engine build we need to make it working :)
For my part i don't have time and experience for the moment to update games mod to work with the last OpenBOR engine version ... but it is the best way...

zanac

@darknior i just try to compille old 4xxx versions but in my allwinner dont work well, several glitch. I think that old version dont work well on rpi

BiZzAr721

@zanac Thanks for trying. The good thing is between the latest & 3400 build we can play 95% of mods. Many of the ones listed do work with 3400 even if it was not made specifically for it. (there may be some unknown bug with doing so, such as Bare Knuckles VI randomly crashing...... but maybe the final version can play on latest OpenBOR!)

Too bad OpenBOR is not backwards compatible - must be very tough for mod developers to keep up.

I made PAK support via CLI available version, Patch version is Галина (galina)
Thanksfully I got some time to integrate this. Worked out of the box! Happy Brawling...

As always I deliver a BETA to test, but I highly recommand to build on your own.

@zanac

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!

This isn't possible on Raspberry and therefore filters are very slow. May you think there is a fix for it?

GitHub account is here and all patches are located here

BiZzAr721

@cyperghost Great work! You don't rest - I will test tonight. Does the 3400 build have CLI support?

Edit
Worked great - called pak from script inside ports menu

cyperghost

@bizzar721 Yes both versions use nearly same patch to provide CLI. It is not so a great thing as you might think about coding. Most work was done by others. Heavy work was done from @zanac and @darknior. Sadly I have no time to test OpenGL for Raspberry. It is not enabled by default or it does not work to 100% with the GL4ES wrapper. Because @zanac wrote he can switch from SDL to OpenGL in his OpenBOR video options.If this would be possible we would benefit from fast screen processing done by GPU and even HQ-filters would run smooth.

About official support...! I think it will not happen. I showed diff patches in Chrono Crash forum and there was sadly no response about this. Of course our work is well appreciated and they show interest for those platforms but it is hard to maintain a platform you do not know. Maybe things will change in time ...

So for now we have to rely on older branches and every new version has to be patched and must be tested. Not hard to do. Next steps on roadmap...,

Try to improve graphics support
More tests from others with positive response
2.1 Does it interfere with other emulators
2.2 Crash scenarios
2.3 Errors in build 6315 openbor and should we use 6412?
Write scriptmodule for build with source and premade binaries
Make it official

BiZzAr721

Unfortunately, your right, I don't see official support happening. It saw it mentioned that they were worried that interest would fade and they would be left with dead weight. (specifically Dreamcast & Xbox).

Raspberry pi is not in the same category as the console specific versions. It is a given that the console version will eventually die. The interest fades when newer hardware comes around. I have an original first run dreamcast I have played openBor on as well as SNES emulators. It was fun for a while, but there are much more efficient/feature rich ways to play. It's essentially a dead end.

Raspberry pi, on the other hand is an evolving platform that goes way beyond just Raspberry pi's, (odroid, all winner) and can be purchased much cheaper than any console. It reaches a much wider audience than just a niche crowd of modded console owners. (And just look at the long lifespan even those had)

Single board computers aren't going anywhere, especially as the price/power ratio keeps improving.
For now at least we got a shunned, but working OpenBOR.

Back to OpenBOR, I was using the command to launch games directly from a script. What command would I use to launch through runcommand?

cyperghost

@bizzar721 I edited nano /opt/retropie/configs/ports/openbor/emulators.cfg

and added

openbor = "pushd /opt/retropie/ports/openbor; /opt/retropie/ports/openbor/OpenBOR %ROM%; popd"
ob_6xxx = "pushd /home/pi/openbor_openbeta; LIB_FB=3 /home/pi/openbor_openbeta/OpenBOR %ROM%; popd"
default = "openbor"

So I have 2 versions available. The old 3400 and the new 6312. The 6312 is much much better than the old one.

BiZzAr721

@cyperghost Thanks. Should I use the same command for 3400 except change the path to the 3400 build?

cyperghost

@bizzar721 Use the pathes as you like. I don't know where you copied the binary... if it is right out if the installer script it is the line of code I wrote above. Then this works out of the box by entering the settings menu (grey box) and select ob6xxxas emulator for running roms ;)

cyperghost

@cyperghost @BiZzAr721 I updated post

I don't know this parameter, why do you use LIB_FB=3 ? I don't use it and it works fine for me on many games ...

So I have 2 versions available. The old 3400 and the new 6312. The 6312 is much much better than the old one.

Yes for sure, the 6312 version is fantastic, almost all my games are working fine with it :)
I"m also using 4.3 Retropie in production, and you are right for Asterix it works fine.
For the moment i only use the 3400 for Bare Knuckle 6 that not start with 6312. But my version also crash with 3400 at some moment ...

For the moment i only have a big problem with TMNT Shell Shocked rev5852 that use i think so many scripts and is really slow when enemies come :(
Rumble not working too
Filters are really slow too without OpenGL
