Thank you Mitu

Please post the complete specs as asked in https://retropie.org.uk/forum/topic/3/read-this-first.

What the error message you're getting when the installation fails ?

@ploinkploink

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.

Should I be concerned about that error?

I'm not familiar with the error, I've updated a couple of times from an older version and didn't encounter it. This happens when you've modified some files outside of git, which shouldn't happen if you only used the RetroPie setup to update RetroArch's core configuration files.

I've only ever used the RetroPie setup so for now since everything seems to be working I'll ignore the error and cross my fingers that everything is okay!

I have seen similar graphical glitches with Driver 76. I get rid of them when I run the emulator with Vulkan enabled. Maybe this fixes the issue with this game. I am using Pi5 and bookworm 64.

@mitu I have resolved my issue it boiled down to two things 1) someone told me to make sure that the keyboard on retropie was set to U.S. which it was not and 2) I was trying to share files through ftp and not sftp. thank you for help

@mitu OK you were right, perseverance payed off, it finally worked :) Thanks for your help.

@sleve_mcdichael now retropie-mount

Just a note: 2X is the default resolution for PPSSPP in the source code. I built it from source recently, and that's the resolution that comes up the first time it's booted.

So, this is not a Retropie specific problem. It's the default for the application. Whether Retropie wants to override the default I'm not sure. Personally I think that 2X with frame skip is way more enjoyable than 1X without frame skip. But that is of course personal preference.

Also, with the Raspberry Pi 5 the default of 2X should run great. Though I won't know until my board gets here.

Cheers.

@mitu Thanks for the help

@sleve_mcdichael You and Exarkuniv doing amazing job with RetroPie-Extra. Thanks!

@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.

@mitu Hello.

I have modified the emulator installation script as follows:

addEmulator 0 "$md_id" "psp" "pushd $md_inst; XDG_CONFIG_HOME=$home/.config/$md_id ./PPSSPPSDL ${extra_params[*]} %ROM%; popd"

So that emulators.cfg looks like this:

ppsspp-1.10.3 = "pushd /opt/retropie/emulators/ppsspp-1.10.3; XDG_CONFIG_HOME=/home/pi/.config/ppsspp-1.10.3 ./PPSSPPSDL --fullscreen %ROM%; popd"

And the operation is as desired, I have separate configuration files for the specific version of ppsspp.

Thank you

@mitu I think just to allow for user preference. Non x11 platforms can only really be full screen. But if it's not working it can be added as a workaround.

There is a new version of ppsspp (v1.13.2), RetroPie is using the v1.12.3. I haven't test this, maybe it have better performance. If you want to test it, you have to modify the ppsspp.sh file and build it from source(it takes 2+hours).

Answering myself, because I'm an idiot. Sorry.

In the emulator's settings (on the GUI) I had to (re-)assign a correct mapping for pause.
It had kbd.esc and two other weird keys from the controller assigned to pause.
I assigned the button behind/below the right shoulder key to pause, no idea what those are called.
Which in my case resulted to the following in controls.ini:

[ControlMapping] ... snip ... Pause = 1-111,10-197 Rewind = 1-67

So, 10-197 is the key that was missing.

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.

Is the PPSSPP emulator even installed ?

Thanks guys, that was exactly the problem. I followed the thread @windg provided, and it worked first time. I really appreciate you guys
