After trial & error, I have pcsx2 libretro core up and running on Ubuntu 20.04
Hopefully somebody can turn this chaos into an unofficial script.
Keep in mind that I'm rusty with retropie configs.

Okay so.. Here we go.

sudo apt remove gcc-9 g++-9 sudo apt install cmake g++-10-multilib libaio-dev libasound2-dev libcairo2-dev libegl-dev \ libegl1-mesa-dev libgdk-pixbuf2.0-dev libgirepository-1.0-1 libgl-dev libgl1-mesa-dev \ libgl1-mesa-dri libgles-dev libgles-dev libgles2-mesa-dev libglib2.0-dev libglu1-mesa-dev \ libglu1-mesa libglvnd-dev libglx-dev libglx-mesa0 libglx0 libgtk-3-dev libgtk2.0-dev \ libharfbuzz-dev libllvm10 liblzma-dev libpango1.0-dev libpcap0.8-dev libpulse-dev \ libsdl2-dev libsamplerate0-dev libsoundtouch-dev libwxgtk3.0-gtk3-0v5 libwxgtk3.0-gtk3-dev \ libx11-xcb-dev libxext-dev libxft-dev libxml2-dev portaudio19-dev zlib1g-dev ccache sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 10 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-10 10 sudo update-alternatives --install /usr/bin/cc cc /usr/bin/gcc 30 sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++ 30 git clone https://github.com/libretro/pcsx2.git && cd pcsx2 && mkdir build && cd build cmake .. -Wno-dev cmake .. -DLIBRETRO=ON -DCMAKE_BUILD_TYPE=Release make -j$(nproc) cd ../bin

If everything goes right, there should be a "pcsx2" folder in the "bin" folder of the root folder.

Make a "lr-pcsx2" folder in "opt/retropie/libretrocores" and move the "pcsx2_libretro.so" into it.

pcsx2-libretros bios seem to be hardcoded to one spot.. otherwise segmentation fault.

Make a "pcsx2" folder in "Home/Retropie/BIOS" and move the "pcsx2" folder from the "bin" folder into it.

Yeah its weird.. the folder tree should look like:

"Home/Retropie/BIOS/pcsx2/pcsx2/bios"

And of course have all your ps2 bios files in that last folder.

Now if you have pcsx2 stand alone installed..

Go into "opt/retropie/configs/ps2" folders, otherwise make one.

Edit your "emulators.cfg" and paste this:

lr-pcsx2 = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-pcsx2/pcsx2_libretro.so --config /opt/retropie/configs/ps2/retroarch.cfg %ROM%"

Make a "retroarch.cfg" and paste this:

system_directory = "~/RetroPie/BIOS/pcsx2"

Now load a ps2 game, be sure to set your runcommand to "lr-pcsx2" and cross fingers.

gcc-9 will be installed whenever you update your retropie emu's.
So you have to go through the compiling procedures above any time you want to update pcsx2-libretro.
Actually after a few times it seems gcc-9 and gcc-10 are installed.

Keep in mind these are alpha builds and purely x64 so no software mode.

Edit your es_systems.cfg to accept .chd in the ps2 section.

If someone can make an unofficial script out of this. It would be appreciated.

@nullfx said in Ipega 9083S Blutooth Controller with RetroPie 4.5:

I know this is way late, but I actually found a way to use the Ipega 9083S on my Raspberry Pi 4 running Retroarch. After the initial Bluetooth setup, manage your drivers and install the sixaxis driver. When that finishes, go to the configuration that shows up and enable third party controllers. Worked like a charm for me.

Also late to the party, but I'm making a Pi 4B powered handheld
and wanted to use this controller for my project.
But before I buy this controller, I wanted to be sure if it would work.

So as long as I install the sixaxis driver, this Android only controller will definitely work ?

Thanks in advance.

@brutaljess sorry we dont support other party images. if recalbox has a forum try asking there.

@unknown nah the memory is emulated, don't think a proper emulator could read the data from a real memory card; that would be cool though.

Thanks for your responses.

@sirhenrythe5th said in Command to edit file permissions (solved):

run into another issue: when i change settings (language, continues) in the atomiswave-servicemenu and push "save & exit"

I mean, yeah. You've just made the nvram read-only, and now you're trying to save changes to it. That ain't gonna work. You'd have to do all that before you locked the file, while it was still writable.

Oops! Missed the part where you said it even happens without changing the permissions.

@greenhawk84
I remember reading in the github page somewhere there was an update involving the joy2key package and you may need to manually update this package.

EDIT: Found the related thread:

@soogs retropie on pi is not supported within any desktop - only running from raspberry pi os command line, with the desktop not running.

@twalls

Hello....
Your thread is probably one of the closest that I can find online for my issue. Any help would be great...

I've built 20 or so arcade 1ups with raspberry pi 3b+ and ran into this problem on the latest NBA Jam build with 4 players. Probably 50% of the time the arcade boots I get a message directly after the emulators load (right when it says done) that emulation station crashed. Talks about changing the theme and if it's the first time loading retropie, etc. Screenshot_20210917-210224_Photos.jpg

I use the same image for every one of my arcades, 4 player and 2 player and have never ran into this problem. I've changed out everything....usb cables, encoders, raspberry pi, surge protector, tried a different outlet, changed the theme, etc. Nothing helps. Sometimes it boots normal and perfectly, but I'd say half the time I get the crashed message. I've tried doing one encoder/joystick at a time and it works fine...all the way up to 3 encoders/joysticks, but when 4 are connected that's when it randomly does it. I've noticed that after I turn on and one of the encoders flashes (red light) instead of staying on is when this happens. And it's random each time of which encoder flashes. Like I've said though, I changed out all the encoders, cables, pi, surge protector. I'm at a loss here and is driving me crazy. Any help would be greatly appreciated. Thanks in advance!

@exarkuniv , sounds good…thanks.

@yarongo said in Pi3B, Xbox Wireless Controller not connecting:

A few questions to @mitu :

Should I uninstall xpad driver first?

No, it's not needed.

Should I install xpadneo directly from Github and not via the menu?

You can try, but the menu installation pulls the latest release tag from the xpadneo Github repository anyway, so I don't think it will make a difference.

@sleve_mcdichael should be fixed now, thanks again for reporting.

@mtlhd1011 said in Psx emulator controls not working:

@dankcushions I can understand that. Maybe a link to the bios section after mentioning it briefly in the first installation section would be helpful I think, kind of like it does with the roms. I didn't realize the bios were proprietary as well, so mentioning that somewhere would help first timers like me understand that better too I think. Thanks for the info, I saw the location section but thought maybe it was something that has to be installed as a program (thinking computer bios) vs. a file drop. I'll see if I can find it and get it going.

I also have an additional question related to my new install. I have one of those nespi+ cases with the fan on it. I was reading their scripts don't work right anymore with the new version of RetroPie. Is that true? I saw someone made a work around with some generic code, but I don't understand it fully.

Update on this, I copied over the bios for each of the emulators that were on my machine previously. Once I did that it broke my PSX emulator again. What I found was that there were a few bios on there that were not supported by the version of the rearmed emulator it currently uses. So I think it picked a bad bios which broke functionality. Once I pulled those unsupported bios from the folder, it functions normally once again. This must've been what happened when I updated my system previously. I also see commodore 64 is broken currently too, probably the same thing there I'll need to dig into. I did manage to get the nespi-case script installed also, I will monitor it to see if that portion has issues.

@dankcushions As it turns out, it was looking for a specific file from a secondary Shock Troopers ROM. Not much to say beyond, "I didn't do my due diligence." The filename in the verbose log was so similar to one already in the ROM that I didn't realize it was actually missing. Also new to me is a Neo Geo game requiring a secondary file. I've dealt with parent and clone ROMs in the past, and even have experience with CHD's and secondary files with CP System III stuff, but this was a new one for me.

I appreciate the confirmation that I had it wrong. Between that and Googling the crc I was able to find the missing file and get this running.

Not sure which version of RetroPie are you using (version 4.4 is too old to support the PI4), but out of the box I think HDMI sound should work using the 4.7.1 image.

Make sure that in the Audio settings in the RetroPie system you choose HDMI as output, then in ES the settings should be:
AUDIO CARD: Default
AUDIO DEVICE: HDMI

For OMX audio output, just use ALSA and it should work.

@bic said in Emulation Station Crashed!:

I'm running a raspberry pi 3b+ with retropie version 4.5.1 along with canakit power supply and image that I put together from a bunch of other images.

Use the image from retropie.org.uk/download, we don't provide support for 3rd party images.

@scabab1359-0 When I first got my Pi, this community helped me learn the basics of RetroPie, Emulationstation and Linux within ONE week, yet somehow you have unsuccessfully been looking for a solution for six months?

You're clearly unwilling to put in the legwork to educate yourself and just want a hand-out without lifting a finger. That's not how it works around here.

@jimmyfromthebay said in Is there any way to use two joysticks for Wonderswan?:

Not sure what you mean by that. There's no such option that I can find under Controls (I have Show Advanced Options set to On).

You need to update RetroArch, this option is only a few months old, see https://www.libretro.com/index.php/retroarch-1-9-6-released/

Ah, thanks. I'm absolutely terrified to update core features like Retroarch in case they've done something moronic that requires the manual alteration of literally thousands of CFG files, like that time they added a new video aspect ratio which renumbered all the other ones :(

"I just had to keep moving it around till I got it right. Once I got it right, I locked in the numbers in the config file."

@jamrom2 Do you mean for Video Pinball? If so, what are your config-file numbers?
