OpenBOR 6xxx OpenBeta Testphase

DavidDraper

Has anyone had any luck running GI Joe A: Attack on Cobra Island? When I unextract the zip, the .pak file is 8k. It runs fine on my PC but the pak does not work in RetroPie.

Ideas?

@daviddraper I've got that running on my Pi, but my PAK file is 83 MB. Try extracting it again. Or you might have the wrong file.

DavidDraper

@g30ff yeah- wierd. I've found it a few different places, but everywhere I find it, there is a .zip file that extracts up into a folder with a few subfolders, including a directory with an 8k .PAK file inside. Is there a way to turn that folder structure into a PAK file?

Hello, I appreciate everyone's interest in getting TMNT running properly. I messaged MersoX to see if they were interested in patching the game. TMNT:RP is a gem of a game, so I hope that it can be fully playable on Retropie.
Just a crazy idea, would it be possible to switch OpenBOR versions like we do with Emulator cores?

@greenhawk84 as i said before as example, I've couldn't run ( swamp and some others levels) rescue palooza on my phone for a long time and even contacted with the guys from chronocrash but all not successful.
And solution was finded as another version of openbor ( it's work with 1.07 -light v2, 1.1.1 and last 1.1.2 versions of tmnt)

-So similarly we just need new version openbor for retropie to have able fully play tmnt

I'm actually a patron of Merso-X and I did let him know about the desire here to see TMNT RP updated for RetroPie. He responded that he'd look into it. That said, given his time constraints and desire to work on new stuff, I wouldn't hold my breath for an update.

Maybe if more of us become patrons and message him he'll be more amenable? Just a suggestion.

@bmovieben i've tried to wait (while communicating with them) normal version for android nearly 2-3 years.... And so we get it? - nope =)

GreenHawk84

@bmovieben there is still a chance that older OpenBOR versions can be applied to certain .pak files and work with Retropie just as it does now. I would consider that to be a more probable option. If I could assign an older OpenBOR as the "core for ROM" then we would be in good shape.

IGA

@greenhawk84 The default version of openbor, that comes with retropie v4.7.1 couldn't even run tmnt (which that not 6510). Or you're mean more older versions?

GreenHawk84

@iga I mean setting up Retropie to have the older version of OpenBOR in order to run TMNT properly. One alternative is to use the old OpenBOR for certain games that need it and then the new OpenBOR for other games, just like we have alternate Mame cores. I don't think that version or option to select an alternate version per .PAK file is possible right now.

@senseless Hi mate, I had probs too as the 6510 instructions in the first post are missing a few keys steps. ~~You shouldn’t need to update the es_systems.cfg manually if the script runs successfully (tried that myself while trying to get it working :) )~~ Have a look at this post which covers the extra steps:

https://retropie.org.uk/forum/post/248619

Edit: I’m talking shizzle, I meant you don’t have to manually add the system, which is something I tried while trying to get it working ... you do still have to edit the es_systems.cfg to tweak the OpenBOR entry that the install script adds.

I finally got it up and running. I needed to do two things:

Add the fullname to es_systems.cfg

<fullname>OpenBOR</fullname>

Modify the emulators.cfg

It seems all it's very case sentitive....

In the emulators.cfg (located /opt/retropie/configs/openbor) I had:

default = "OpenBOR"
openbor = "/opt/retropie/emulators/openbor/OpenBOR %ROM%"

After changing it to:

default = "OpenBOR"
OpenBOR = "/opt/retropie/emulators/openbor/OpenBOR %ROM%"

The system worked!

Thanks for your help ;).

Hello everyone, first of all i want to thank @darknior @zanac and @cyperghost for making this possible. I managed to install multiple OpenBOR versions with CLI support on Ubuntu 20.04 and I'm so glad this worked out that I registered here and give @construkt and anyone interested a quite detailed instruction on how to get this to work on Ubuntu.

Prepare for building.
After setting up your building environment install the dependencies needed to build OpenBOR from source:

sudo apt-get install libsdl2-dev libsdl2-gfx-dev libpng-dev libvorbis-dev libvpx-dev yasm

""

Unfortunatley building with the latest compiler didn't work so you have to change it to an older one (gcc-7 or gcc-8) - to do that follow the instructions here: https://linuxconfig.org/how-to-switch-between-multiple-gcc-and-g-compiler-versions-on-ubuntu-20-04-lts-focal-fossa

Download the source and the patch-file
Download the zipped source code of any version you want, in my example here i take version 7142 (https://github.com/DCurrent/openbor/archive/refs/tags/v7142.zip) and 3400 (https://github.com/crcerror/OpenBOR-3400/archive/master.zip).
Now get the patch from here: http://raw.githubusercontent.com/crcerror/OpenBOR-Raspberry/master/patch/latest_build.diff
Edit the diff-file
To make this work you have to open the patch file with a texteditor and delete everything AFTER

 #ifndef SKIP_CODE
 	getPakName(pakname, -1);
 	video_set_window_title(pakname);

Apply the Patch
Extract the downloaded zip-file and put the edited patch inside the /engine folder. In the engine folder open a terminal and apply the patch with

patch -p0 -i latest_build.diff

Make build.sh executable with

chmod  +x build.sh

and build the binary with

./build.sh 4 amd64

Go to /opt/retropie/configs/ and create a "openbor" folder with an "emulators.cfg" file inside - make the folder and everything inside owned by current user with

sudo chown -R $USER /opt/retropie/configs/openbor/

Open the emulators.cfg with a texteditor and put this inside:

openbor-7142 = "pushd /opt/retropie/configs/openbor; /PATH_TO_THE_BINARY_FOLDER/OpenBOR %ROM%; popd" 
default = "openbor-7142"
openbor-3400 = "pushd /opt/retropie/configs/openbor; /PATH_TO_THE_BINARY_FOLDER/OpenBOR %ROM%; popd"

edit es_systems.cfg and put this inside:

  <system>
    <name>openbor</name> 
    <fullname>OpenBOR</fullname>
    <path>/PATH_TO_YOUR_ROMS_FOLDERS/openbor</path> <extension>.bor .BOR .pak .PAK</extension> 
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ openbor %ROM%</command> 
    <platform>pc</platform> 
    <theme>openbor</theme>
  </system>

create an "openbor" folder in your roms directory and put your games in it.

So now you are good to go and start playing :)

@tardigrada First off, thank you for all this information. Following your instructions I had a couple things I might recommend you add in to the instructions...

Apply the Patch
Place the edited patch inside the engine/ folder. Then, ensuring you've navigated inside of cd engine/, apply the patch with...
Build the binary
Make build.sh an executable by performing
chmod +x build.sh
Then build the binary with...

And finally I got stuck on the build with the following error. Any suggestions here? I don't have Ubuntu installed.

@bmovieben Thanks for your suggestions - I've edited the post. I guess the instruction wasn't that detailed after all :-)

@bmovieben said in OpenBOR 6xxx OpenBeta Testphase:

I don't have Ubuntu installed.

What's your OS then? The given instruction only applies to Ubuntu/Debian based x86 (64 bit) systems..

BMovieBen

@tardigrada I just have the retropie 4.6 image installed.

tardigrada

@bmovieben OK, from your code-output i can see you are on a RaspberryPi - so that Method won't work... Also i don't understand why you try it the hard way by compiling yourself when there's a straightforward, easy to use solution for pi users provided in the opening post...

IGA

Any news about resqua-palooza?

BMovieBen

@iga Nope sorry. You'd be better off finding a PC to play it on, I don't think he intends to upgrade TMNT Rescue Palooza to a newer version of OpenBor.

IGA

@bmovieben i play on phone, but on crt-tv it's looks greater...
But at all idea of new version is clear

GreenHawk84

@bmovieben is there a way to use the version of OpenBOR that TMNT was built for just whenever I want to run that .pak? So, I would have 2 versions of OpenBOR installed on my Pi4?

BMovieBen

@greenhawk84 The one included with TMNT RP is built for PC, so you would have to figure out how to build that specific version for the Pi, hope that it functions the same as the PC version, and then figure out a way to get the two versions of OpenBor to coexist on a Pi. I had the same thought but got stuck at the "build for Pi" step and messed up my RetroPie setup. Once I got it back to working I decided to stop messing with it (for now). Godspeed if you try this though!
