@mitu Yeah, that's what I did, essentially. Thanks a bunch!

@retrofdi

So, you get the same results on fresh install...And just spit balling per say, how many video ports do you have? Additionally, have you tried any other displays? My thoughts would be the next thing to look at the communications via HDMI (Assuming you are using HDMI based on the hardware). I would use a known/good HDMI cable, attempted another port, and another display is possible.

@mitu said in Sega CD Game Not Loading - Annett Futatabi:

What's the actual name of the file you're launching (.cue, .chd) ? I think some characters from it might trigger this error in runcommand.

Annett Futatabi (Japan).chd
Annett Futatabi (Japan).cue

I just renamed the file to "Test.chd" and guess what, it boots! Thanks for the help.

@sleve_mcdichael aahh ok, so it's cause it's not on a Raspberry, ok that makes sense then. Thank you

@mitu It looks like there were some dependencies missing that we're causing the issue.

To fix this, I ended up installing aptitude and installing the missing packages simply because aptitude gives much better verbose output for dependency issues as well as a simple way to resolve the conflict.

After installing the missing packages the basic install went through without issues.

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.

@mitu This help request can be closed out. I ended up uninstalling retropie and Ubuntu and put Batocera on my SSD. Batocera seems to be more user friendly in terms of initial installation and settings. From what I've read Retropie has more options/settings but my emulation needs are simple and Batocera serves me well.

@mitu Thanks again for your help.
It appears to be every Emulator, nothing is working now. Will start again and hope it works.

@litsince which stock image? We don't support this system currently.

Well, It turns out that my sound problem was probably due to the display refresh rate not being on sync.

After many reinstalls (both OS and Retropie) I was able to make sense of all this and I now can enjoy Retropie again on my old laptop with Lubuntu 20.04.

Thank you mitu for your time, this is really appreciated.

Forget it, everything works fine! My mistake. :)

Run emulationstation --debug from a terminal window and post the output. My guess is that there's no HW accelerated GL support, but the log output would help confirming the assumption.

@norstein said in pcsx2 won't install // unable to locate package pcsx2-unstable:

Maybe installing add-apt-repository should be included in the base installation, since it is used for several packages?

software-properties-common is installed by any *-desktop meta-package, what options did you choose during installation ?

What's your use case ? When do you want to display the marquee - gameplay/game browsing ?

@mitu

Looks like the Nvidia driver I had installed was the culprit. I removed it and used the Nouveau one and Emulationstation now starts but launching games fails. I am troubleshooting further.

@mitu said in Caps Lock capture problem:

Try pressing Scroll Lock first.

Thanks for replying mitu, much appreciated. I will try this as soon as possible. :)

@Paxi said in RetroPie on Ubuntu Mate 20.4.01 HDMI sound issue:

there is only a 32bit version available.

RetroPie has only experimental support for 64 bit on the Pi, using the Raspberry OS 64 bit beta version.

Isn't there anything more I could try, specifically in RetroArch/Pie config?

You can try to disable PulseAudio and make sure RetroArch uses ALSA.

Not that I know of.
