OpenBOR 6xxx OpenBeta Testphase

SinisterSpatula · 12 Jul 2019, 14:57

@cyperghost Most recently I used a stock image: retropie-4.4-rpi1_zero.img which should be stock standard, nothing but enabling ssh, samba, I did a fake-hw-clock to stop the system file checks on every boot, I installed xboxdrv (I like to use that for gamepad remapping to keyboard keys. That's all I've done I'm pretty sure.

cyperghost · 12 Jul 2019, 14:57

@SinisterSpatula Okay then wait for an answer from mitu. I think he can help

@cyperghost said in OpenBOR 6xxx OpenBeta Testphase:

@mitu Can you help here please?

I can try, but it looks like the problem is that the binary/some parts of it (gl4es ?) are compiled for a RPI3, while the PI0 has a different CPU, thus some optimized instructions in the binary will not work for it.

SinisterSpatula · 12 Jul 2019, 15:00

@mitu that's what it seems like to me too. What's weird though, is if you look in this thread starting here: https://retropie.org.uk/forum/post/191200 another member was able to compile this beta for the zero. They don't say what they did or how they did it though :(

cyperghost · 12 Jul 2019, 15:01

@mitu No it's compiled by the scriptmodule and GL4ES is deleted. So it's ARM6 instructions. I've never compiled on Pi1/0 platforms and I don't have one available.

ldd looks okay

Ah, then it's not the CPU instructions mismatch.

SinisterSpatula · 12 Jul 2019, 15:03

@mitu Well, it could be... See I'm doing the scriptmodule first. But then I'm compiling again, and overwriting the binary with my own. I'll try just the scriptmodule alone, maybe that's the issue?

cyperghost · 7 Dec 2019, 16:06

@SinisterSpatula Then the GL4ES is wrong. The scriptmodule uses a prepacked GL4ES made for RPi3 therefore I asked to delete this.

Maybe you can compile GL4ES on your platform.
Instructions are here

SinisterSpatula · 12 Jul 2019, 15:06

@cyperghost Yeah, just to clarify, I was doing script module, then compiling my own openbor executable, and my own GLES4, and overwriting them both, into the folder of where the scriptmodule installed to. Is the script module able to change the compiling flags to the needed ones for zero? Or would I need to modify those before compiling?

cyperghost · 12 Jul 2019, 15:09

@SinisterSpatula The scriptmodule has nothing to do with compiling flags. It's the patch itself.

Compiling flags are set to

CFLAGS         += -marm -mcpu=cortex-a9 -mfpu=neon -mfloat-abi=hard -fomit-frame-pointer -ffast-math -O2

SinisterSpatula · 7 Dec 2019, 16:15

Would you happen to know what the flags should be for the zero? I'm guessing these are working for pi3 but for zero it needs to be something other

Edit: looks like this maybe? "mcpu=arm1176jzf-s -mfloat-abi=hard -mfpu=vfp (alias for vfpv2)"

SinisterSpatula · 12 Jul 2019, 15:20

Sorry to drag you both into something silly, I've just got my heart set on getting this to work lol, and I truly appreciate the assistance :)

cyperghost · 12 Jul 2019, 15:26

@SinisterSpatula You can try -mcpu=arm1176jzf-s -mfpu=vfp

SinisterSpatula · 12 Jul 2019, 16:03

@cyperghost said in OpenBOR 6xxx OpenBeta Testphase:

-mfpu=vfp

That did it!! I'm so freaking happy right now! Woooooo! :D Thanks again, sincerely appreciate it. For future others who want to compile for zero, If you want you can point them to my changed 4-Galina-diff here:

cyperghost · 7 Dec 2019, 17:30

@SinisterSpatula Sure... The community has to thank you even if you plan to release some premade images.
Can you say something to the speed?

About the emulators.cfg
it should be

openbor = "pushd /opt/retropie/ports/openbor; /opt/retropie/ports/openbor/OpenBOR %ROM%; popd"

The %ROM% is needed to start PAK-files through dialog menu or via EmulationStation as own system.

SinisterSpatula · 7 Dec 2019, 18:15

@cyperghost Thanks, yes the rom's are starting just fine, I need to spend some time on getting the controls working correctly (for my gpi case) and the speed is good. You can tell that the games are not used to playing on a small screen, and that they could use some optimization. Even without tuning the image and video files, they seem to run well (depending). Like HE-MAN the video is laggy because of the large video resolution (and the poor zero's framebuffer trying to handle it). But once the game starts, speed is very nice. Oh, no, I don't need any thanks, you and @zanac and the rest of retropie team, and the OpenBor team are who to thank for this. I'll put links here to quick video clips of it in a moment. I don't know if we can ask the OpenBor team if they are interested in releasing low-res re-pak's for our purpose, with the popularity of the Gpi case, the pi zero is really going to start getting a lot more use and attention. Or, if this can or should be a community effort, I'm happy to put in some work on this. On the topic of pre-made images, I understand the issues surrounding that, and wish people would use stock images, myself personally. I think if Retropie added more official images (for example a stock image targeted for the Retroflag Gpi, which incorporates many of the fixes and addresses the problems that the community is currently working-around, like including a binary for xboxdrv because people honestly don't want to spend an hour compiling that), but there's probably issues with that and reasons why that's not the case, and probably a topic that's been tossed around before, but yes, I can see the viewpoint of why premade's are a bad thing, without a doubt.

Yes that is true for a small part. I think it's a usefull to prepare ready made images for different platforms (Pi0, Pi3, Pi4, XU4 ...) but it is not usefull or demanding for ready packed images.

I rather think that people like you could incorparate a "scriptmodule" that prepares the vanilla RetroPie image. I've read your github wiki and I think you are on a right path by providing helpfull information together with some small how to's. That's really a nice way to contribute ...

The problem about premade images I see, that people download these images and sell them. Then a software problem occours and because it's RetroPie and this is the RetroPie forum, people (the buyers) ask here for help. It's very difficult to give advice if you barely don't know anything about the config.
Btw: I doubt you sell your images, so don't feel offended.

Most of these premade images are not well made. Not because they were flicked together, no ... they get very old and lack of updates. In less then 3 month they are outdated.

So maybe a incooperation of a downloader script, that prepares ready setted binaries, exchange some themes, download game modules like OpenBOR could be the solution and then there may be a better mood for "premade" images because then the code is open and we have a "behind the scenes"-setup and better help is possible.

EDIT:
I will prepare annother script module for the RPI1/0
According to the changes done in diff-patch.

SinisterSpatula · 12 Jul 2019, 18:49

That is fantastic!! I love your idea of using script modules instead of ready made images. Once I get a little better at scripting, I will make that my goal and the method I will aspire to achieve! And yes, that is the huge can of worms with images, you never really know what's inside. We are on the same page for sure.

@SinisterSpatula
Hey,
Ninja Turtles Rescue Palooza .
Can u get the stage with the van on the left working ? (VAN) or even the PARK ?
its dosent work at my place just make the name jump up and down... (tried to finish the game )
Try it on the cpu working fine...

SinisterSpatula · 13 Jul 2019, 02:13

@shavecat I saw that bug also. I'm curious if I tried dmitri if it might work on that one. I think the thing we need to keep in mind though, is I'm pretty sure the pak is only supported for PC, and it just "happens" to also play on the other platforms. The dev of the pak doesn't test it on our platform, so we may have to see if there's ways to fix these things on our own. I'm curious to look at the code for it, and compare it to those other "entrances" and see what's different.
