Adventures with ODROID XU4 and RetroPie

Looks like it's pulling from the main original repo, actually.

pfox__

@zerojay Yes you beat me to it :)

pfox__

@zerojay But if that were the case then the output we see above makes no sense... I think it's pulling from libretro's fork? https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/libretrocores/lr-ppsspp.sh#L29

That would appear to be the case (although I need my logs of my failed ppsspp build to verify, which I don't have access to atm).. here we see the old version of the code: https://github.com/libretro-mirrors/libretro-ppsspp/blob/master/Core/HLE/sceMpeg.cpp#L771

So I guess that is where we should target for the fix, then.

zerojay

Sorry, I should specify here. I was looking at the standalone version which appears to pull from main, not lr-ppsspp.

pfox__

@zerojay lol there's a PR for this very issue languishing in the PR queue on libretro's version. https://github.com/libretro-mirrors/libretro-ppsspp/pull/85

zerojay

Pretty sure they are using https://github.com/libretro/ppsspp/, not https://github.com/libretro-mirrors/ppsspp/ and it looks like that change is already there.

@zerojay Do you have access to the full RetroPie-Setup log that you used when pasting your error from building lr-ppsspp in the OP of this thread? That should show you which repo it cloned from. I'm away from home right now, so I won't be able to verify this until later, but I think the build error is because retropie-setup is using the scriptmodules/libretrocores/lr-ppsspp.sh script to drive it's build, not the standalone at scriptmodules/emulators/ppsspp.sh.

Here are the relevant lines in the respective scripts mentioned above:

lr-ppsspp.sh: https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/libretrocores/lr-ppsspp.sh#L29

        gitPullOrClone "$md_build" https://github.com/libretro/libretro-ppsspp.git

The above repo redirects to libretro-mirrors/libretro-ppsspp. This is the repo that DOES NOT have the 33c396 commit fix for the ffmpeg issue.

ppsspp.sh: https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/ppsspp.sh#L26

    gitPullOrClone "$md_build/ppsspp" https://github.com/hrydgard/ppsspp.git

This repo does have the fix we've been discussing.

Please let me know if I'm missing something, here. As I said, if you have your full logs on hand, you can verify this for yourself. Otherwise I will follow up later today when I have a chance to check myself.

zerojay

Okay, for lr-ppsspp, the logic is that if the platform isn't rpi (as it isn't for us), then it would use https://github.com/libretro/libretro-ppsspp.git to build from, which as you pointed out is the mirror without the fix we need. I think I'll fork it, add the fix we need to it and attempt to build to see what comes out of it.

EDIT: It got past sceMpeg.cpp... fingers crossed.

Okay, it compiles and runs and runs quite well with no tweaking. Burnout Legends ran full speed with only the occasional slight blip however it does appear that actually playing MPEG videos is busted. So for the menu backgrounds of Burnout Legends which are all MPEG videos, they don't properly play and it appears there's output about an unsupported format (it's difficult to read as it's outputing the text to the screen which gets overwritten quickly. (Might be my fault as I had a local change for the lr-ppsspp script that might have caused it, giving it another shot.)

EDIT2: Appears my tweak didn't help or hurt anything. So the error being output is videoc_try_fmt:401 Unsupported format for destination. Looking into it.

Also, for awareness, this is building PPSSPP 1.0.1 which is quite old now. Going to try http://github.com/libretro/ppsspp.git now to see how that turns out.

I just tried to install the ppsspp script, via retropie_setup.sh, that sources itself from hrydgard/ppsspp and got the same build error as @zerojay shows above. That error message is referenced in a few psspp issues (https://github.com/hrydgard/ppsspp/issues/2936 & https://github.com/hrydgard/ppsspp/issues/9032 ).. Not sure what to make of it yet.

@zerojay,

There's an ongoing effort to implement libretro support directly into the official ppsspp repository. I would suggest waiting for the PR to be accepted before wasting too much time on what will hopefully soon be an obsolete repository.

There have been problems with the vanilla ppsspp build related to GLES support for Pi recently, too. I sent some fixes that have been merged in the last week or so, but as of last night, the build had a new issue on Pi, where it's setting up a 960x544 window size instead of the actual fullscreen resolution.

advmame appears to only show in the top left corner at a tiny resolution.

Added this section to the OP so that I don't lose it.

Hi there!

Would any one of you have an idea why my lr-mame2010 on my XU4 based on the 4.14 kernel (minimal image from December 2017) would not load roms?
When I manually launch the core with retroarch in the command line then I can see mame-2010 always complaining that it does not find any of the files even though those files are definitely part of the rom's zip archive.
I double and triple checked if the roms are really 0.139 but they are and they work on a Rpi3 mame-2010 build.
File permissions on the arcade folder (that's where they are stored on my build) are set to rw-rw-r--.

What am I missing - why does mame-2010 not like my roms? :)

Best,

Tillman

P.S. I just built lr-mame2010 directly via the retropie-setup.sh script - allegedly without any issues.

*** UPDATE ***

I can confirm that the issue is definitely caused by the new build.
I have replaced the core with a known-to-be-working build from a couple of weeks ago and all roms work flawlessly.
Only the new build complains about the missing files (all of them) inside the zip.

So what might be causing this?

Best,

Tillman

@zerojay Hi there!

I was wondering if you also encountered the lvl0 failed to get mixer ALSA issue after you have installed Retropie on your XU4 with kernel 4.14.
It is not really a critical issue for me as sound works in the snap videos and also in all the emulators but it sure looks not so very polished seeing this error appear in ES when switching the systems.

Any idea how to fix this?

Best,

Tillman

zerojay

I switched over to the premade image based on kernel 3. Sorry.

zerojay

Updated the method of getting full screen on advmame to allow it to be automatic and a bit more... proper.

Does anyone has been able to get scummvm working on xu4. Emulator install should be in "opt" section according to scumm.sh file but it is not.

zerojay

@yaazzz It's likely masked out with a !mali flag. You can remove it and you should then see it show up in RetroPie-Setup. Try installing it and let us know if it works.

Thank you : that's was the trick. Everything went well : compilation and game launch. I only need To understand how To use the Ds3 with scumm now.

BuZz

@yaazzz if it works fine, I can enable scummvm for mali targets. Thanks.
