@death said in Help installing older version on PPSSPP:

"Error running 'git clone --recursive --depth 1 --branch master /home/pi/retropie-setup/tmp/build/ppsspp/ppsspp' - returned 128

Try to use the 'clean source folder' option before building from source, you may have an older source build that's in the way.

@quicksilver said in Sounds issues PPSSPP (PE 3rd Birthday):

I would suggest looking here first to see if its a known issue. If not, then make a issue report so the PPSSPP devs can look into it.

https://github.com/hrydgard/ppsspp/issues

I don't think it is a known issue as I have seen other people emulate it, even on a Pi 3. I feel like I am missing something here but I don't know what. The graphics are smooth and the FPS is stable, but the sound is driving me insane.

@sirhenrythe5th said in PPSSPP menu showing text:

I use it wired most of the time as my cats disturb the Bluetooth connection by sitting on my lap (no joke :D)

Your cats are radio-active :)

....But not completely. I saved state during the "off to Mist village" intro animation and now the game never runs anymore, even after deleting the saved state and reinstalling the rom.

the logs show:
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-ppsspp/ppsspp_libretro.so --config /opt/retropie/configs/psp/retroarch.cfg "/home/pi/RetroPie/roms/psp/FF4CC.cso" --appendconfig /dev/shm/retroarch.cfg
glGetError 0x500

I'm mainly wondering if there's some other, deeper config besides the retroarch file in the ppsspp folder somewhere that got distorted by my save state.

@phane Thanks for the tip, now it's working properly!

@mitu i'm back if you're still here for some reason...
i tried again for the log.
here it is: https://pastebin.com/U96FjKBt

Just saw this on my own system as well. Looking at PPSSPP's automated testing, it definitely seems to be a regression on their end, so I'll raise something on their forum/github.

@stumcbill said in How to donwngrade PPSSPP to v1.5.4 (solved):

Ah ok, is there anyway I can reinstall the version that comes with 4.7 to see if it makes a difference?

Since PPSSPP isn't installed on the 4.7 image by default, even if you download the 4.7 image, installing from binary will still get you the current/last version. So, no - you can't reinstall the old version from RetroPie-Setup.

Ah, I never realised that. Sounds like I’m out of luck then.

Thanks

@mitu holy cow, it actually worked. Them guys are really quick, seeing how I installed the emu only last week.

Thanks :)

@huey no, let me check it

@kay-row it should still generate a log in the same location, after launching as normal

@ReadyPlayaWon thanks!
I removed the other PPSSPP I had and installed the lr-PPSSPP package, the controls all worked out of the box!
Thank you again!

In 2.0.10, it looks like a hint was added (SDL_HINT_GAMECONTROLLERCONFIG_FILE) to point to a user chosen 'gamesdbcontroller.txt' file. It looks like PPSSPP doesn't use this mechanism to load the file, but it might affect how SDL2 works when the game controller API is initialized by the emulator.

I'll see if a recent source build for PPSSPP triggers this on a RPi, it could also be something that's changed in the emulator since the last binary build in RetroPie.

@quicksilver
In buffered I get this, but I don't know how to change it in lr-ppsspp, but in ppsspp it gives me a black screen.

@Gumdoc said in PSP questions:

I downloaded it last night from source.

Its been a week or two since I last updated ppsspp. It was working fine for me last I checked (Ill update and test on my end to see if there has been a regression). Specifically what games are you testing? If they arent running fullspeed you can have audio issues. Can you try resetting your settings to default in the ppsspp menu, perhaps you accidentally changed something there?

@yeetus-mcreetus can I ask how you installed it and everything? I'm struggling with it

@quicksilver
It had passed 4 months before I actually tried your fix proposal.
It worked. The X-box controller is now fully compatible. Thank you!

@rodolfoaguilar @Firebird_WS6
I'm summing up what quicksilver proposed.
This solution worked for me.

Plug in a Keyboard While in Emulation Station press F4 to open the Terminal Type sudo nano /etc/modprobe.d/xpad.conf Change
xpad triggers_to_buttons=1 to xpad triggers_to_buttons=0 Press cntrl-x Accept the changes. Return back to Emulation Station by typing emulationstation Restart Retropie.
(In my case, I noticed that the X-box controller had started acting strangely while in Emulation Station.
The D-pad buttons swapped positions in Emulation Station as they were previously in PPSSPP.) Remap the controller in Emulation Station. Remap the controller in PPSSPP if necessary.
(In my case, this was not needed.)

I'm not sure why this issue is affecting some people and not others.
Apparently, the problem is caused by the Trigger buttons somehow.

Ahh.. got it. Thanks for your help, I changed mirrors in sources.list and I'm good to go. Should have thought of that. That's what I get for doing a rebuild at 3 am on a Saturday night.
