On my RetroPie system, this error was due tu a wrong kernel. And the wrong kernel was due to an upgrade to Debian 11 (which I should never have done) and downgrade to Debian 10.

apt install --reinstall raspberrypi-bootloader raspberrypi-kernel
and reboot solved the issue.

@memorylane said in Cannot compile lr-ppsspp (ffmpeg arc4random implicit declaration error):

@mitu Is it only a matter of updating the source version in the install script?

Seems like it.

Which version did you try?

Latest stable release is 14.4 AFAIR.

Can you add more details about your setup, as requested in https://retropie.org.uk/forum/topic/3/read-this-first ?
What program did you install for i2c ? Or maybe you just enabled i2c through raspi-config ?

Can you post the complete verbose log on pastebin.com ?

@mitu said in lr-ppsspp crashes on hotkey reset:

Is there a similar issue reported for PPSSPP ?

I didn't see one, but the repo is pretty active and there's a lot to sift through so it's possible I may have missed something.

The closest one I found was this one, also for the libretro core; I'm not sure if it's the same issue since I didn't test any of those other actions and I'm not sure if Sync Audio is enabled or not -- I can test some more next week.

If i would use Ipac2 in keyboard mode is this better for the Retropie experience?

Not necessarily.

I choosed the gamepad mode for the configuration under Emulationstation for two players . Because in keyboard mode is only one player input configuration is possible (but Keyboard mode functioning under PPSSPP awesome). I know under Retroarch I have a possibility to configure a second player input too.

Yes, you can configure a 2nd player for a keyboard device, but that can't be done from EmulationStation and you'll need to edit the configuration files (retroarch.cfg). RetroArch expects mostly a gamepad since it started as a console oriented front-end emulator.

I don't really understood configuring inputs under Emulationstation , is this for the standalone emulators or just for the controlling / steering the Emulationstation. Retroarch is for the Libretro emulators input configuration ( I hope this is right ?)

Configuring the inputs in EmulationStation will auto-configure them also for RetroArch and a few other standalone emulators (Mupen64Plus/Daphne/OpenMSX). Any libretro based core should have a configuration ready once you've done it in EmulationStation.

This is getting off-topic here, if you have some more input related questions, I suggest starting a separate topic and reference your posts from here.

@mitu they are!!!
Thank you so much, perfect advise - as usual!

got an answer in the dev-forum of ppsspp: this issues is caused by new saving-routines, also the paths have changed/shortend (from /roms/psp/psp/system/ -> /roms/psp/), so you will find saves on the memorystick there since 31.01.2022.
The issue is well known and should be fixed with the next update in a couple of days.
FYI, even if i seem to be the only one here using / updating the lr-ppsspp-core :D

Got it, someone from the official ppsspp-forum had the final hint.
I share this here for everyone running in the same issue (which should happen if you updated recently):

"RE: graphical issues since last update
Turn off the vertex cache setting.

It used to be accidentally disabled in code, but we re-enabled it recently. It seems to be malfunctioning on some devices now, though. It was accidentally broken for several stable versions."

@ffaddic thanks for info.
I am aware that you can force retroarch to get updated even without being supported by the retropie setup-script.
I prefer to wait until retroarch gets verified and 1.9.x (even .13 maybe?) will be part of the official setup-script to avoid running in other issues :)

Thanks for the advise concerning *.cso.
I just had a look, i only have *.iso on the pi while in fact having lots of *.cso on my real CFW-PSP1001 ;)

@mitu Thanks for the reply! I’m not at my Pi at the moment but when I get situated, I’ll give that a shot and report back!

Hello , i have more problems GTA games , Vice City , Burnout dominator and some other i think the most recent PSP games boots fine and menus are ok.
But in the game the graphics are broken and unplayable. Cars and people falling trough the road and grass etc.
Same roms / dvd content are fine on ppsspp win10 desktop machine.

Tried vulkan on the PI4 but more and the same problems, also tried booting retropie standalone image and on twister os same result.

PI4 / 8GB
32 bit or 64bit kernal on twister os same problem.
ppsspp without retropie same problem.
Al on the latest updates of may 2021

Can anyone give some advise.

@stumcbill
The only two things I can think of are

Drive is full File permissions issue

#1 is easy enough to check, #2 shouldn't be an issue as long as your USB drive is using the FAT32 file system.

When you say you manually save, if you mean through the game's normal save feature, you could try using a save state as an alternative. If a save state worked then it likely would mean that none of the above applies and it is something else.

@mitu i'm back if you're still here for some reason...
i tried again for the log.

Using Retropie on a Raspberry Pi

PSP games in .pbp format will work fine in ppsspp and lr-ppsspp

PSX games in .pbp format will work fine using lr-pcsx_rearmed

What do you think about my findings friends?

@windg thanks man, i will check it later...I assume that the issue has to do something with the raspberry pi GPU, cos having the latest source, latest PPSSPP version, overclocked...could it be a GPU malfunction?
