      Hi everyone,

      I'm recently compiled RetroPie 4.8.9 in my raspberry pi zero 2 w for retro gaming in emulators like snes or megadrive. I have Raspberry Pi OS bookworm 64 bit and a HyperPixel 4.0 Square display (with 1:1 aspect ratio and 720x720 resolution) pluged through the headers.

      Emulationstation open well and recognize my roms, but UI sometimes freezes up forcing me to hard reset my raspberry pi (unplugging and plugging the power supply again).

      When the rom try to load, a few seconds pass and then return to the emulationstation menu.

      I've tried to run the rom manually with next command: /opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ snes /home/pi/RetroPie/roms/snes/my-rom.sfc

      and enabling debugging mode I can see this errors:

      [ERROR] [KMS]: Error when switching mode.
[ERROR] [Video]: Cannot open threaded video driver.. Exiting..
[ERROR] Fatal error received in: "video_driver_init_internal()"

      What can I do to solve this missbehavior?

      This is my /boot/firmware/config.txt file:

      dtparam=i2c_arm=off
dtparam=audio=on
camera_auto_detect=1
display_auto_detect=1
auto_initramfs=1
dtoverlay=vc4-kms-v3d
max_framebuffers=2
disable_fw_kms_setup=1
arm_64bit=1
disable_overscan=1
arm_boost=1

[cm4]
otg_mode=1

[cm5]
dtoverlay=dwc2,dr_mode=host

[all]
dtoverlay=vc4-kms-dpi-hyperpixel4sq

      Any help is welcome, thank you very much!

        Please provide the entire verbose log (on pastebin.com) from a failed launch and also the output of kmsprint -m.

        Any reason you're not using the RetroPie pre-image from the downloads section instead of the Bookworm installation ? The product page says Hyperpixel 4.0 Square is not yet fully compatible with recent versions of Raspberry Pi OS,..., so it may be working better with an older RaspiOS version (such as the one on which the RetroPie image is based).

          Hi @mitu, thank you so much for the fastest response.

          The display works well, if I run retroarch manually, games are running ok. So maybe the problem is runcommand instead.

          I'm working in a personal project, I need to compile retropie in my own debian installation.

          Here are the full log and output text of kmsprint command:

          Can be libgamemode.so the problem?

            @libredeb said in RetroPie doesn't load games on manual installation in Raspberry Pi OS bookworm 64 bit:

            Here are the full log and output text of kmsprint command:

            Please use pastebin.com for large text logs, as I asked in my post. Can you also post the contents of the /dev/shm/retroarch.cfg file ?

              @mitu yes, sorry for forget to use pastebin. The output of /dev/shm/retroarch.cfg is:

              $ cat /dev/shm/retroarch.cfg 
video_refresh_rate = "60.00"
video_fullscreen = "true"
video_fullscreen_x = "720"
video_fullscreen_y = "720"
libretro_directory = "/opt/retropie/libretrocores/lr-snes9x"

              The freez up issues I was able to solve disabling transition effects and compiling retropie-emulationstation manually (without Retropie-Setup script) following the instructions in README.md file.

                The error in the logs is from RetroArch (erronously) trying to change the video mode according to video_fullscreen_x = "720" and video_fullscreen_y = "720" options in the retroarch.cfg file.

                Add a user script to clear the video_ options from the file in /opt/retropie/configs/all/runcommand-onlaunch.sh with the contents:

                #!/usr/bin/env bash
sed -i '/fullscreen_[xy]/d;' /dev/shm/retroarch.cfg

                Since your display has only 1 video mode, there's no need for specifying the video mode anymore.
