I did use a HDMI splitter in the previous versions but it never worked correctly. I even tried two different models that weren't that cheap. It was pure luck if the signal was right. I tried changing the power on order and changed every pi HDMI setting I could find. And a HDMI splitter is not the elegant solution I'm looking for. One less device in the setup is better. Or as Elon sed: "The best part is no part."

You can remove the USB drive as long as you don't need to read stuff from it.

I don't have any issues with Dosbox using the dev branch on a PI4 - did you set any special resolution for it through the Runcommand launch menu ? I just installed it from scratch and it's using the default configuration file installed by the scriptmodule. Same thing with dosbox-sdl2 - it's working just after installed with the default configuration.

Ok, both pages now follow the master branch.

@shavecat said in Raspberry PI4 Couple of Q ?....: "You can backup ROMs and configs and copy them back. It's not a long process really. " Will take a couple of good hours or more ..... It depends on your setup and how you want to do it. -If you have a linux machine then you can just plug the sdcard into your computer and copy them over at USB 3.X speeds. -If you keep your roms/settings on an external usb drive (this is how I do it), then you can just unplug the usb stick/hdd/ssd and plug them into another computer to copy/backup. -If you are going over the network through something like WinSCP, then yes, that is painfully slow. Ethernet connections on both the pc and Pi make this a more tolerable experience. You can also follow this guide: https://retropie.org.uk/docs/Running-ROMs-from-a-USB-drive/ This is meant to set you up to run roms externally, but it will also copy your entire Retropie folder to the usb drive. Then just unplug it after it is done and plug it into a computer to copy over. Just make sure to preformat the drive to be readable by whatever OS you plan on reading it. Hope this helps a little.

Thank you @mitu That worked, I needed to throw in a --disable-x11 too: CFLAGS="-O2 -march=armv8-a+crc -mtune=cortex-a72 -mfpu=neon-fp-armv8 -mfloat-abi=hard -ftree-vectorize -funsafe-math-optimizations" ./configure --prefix=/opt/retropie/emulators/retroarch --disable-sdl --enable-sdl2 --disable-oss --disable-al --disable-jack --disable-qt --disable-pulse --enable-opengles --disable-videocore --disable-vulkan --disable-wayland --enable-kms --enable-egl --enable-floathard --enable-neon --disable-x11 I may have got rid of the --prefix bit, I can't quite remember now. Appreciate the help. Mr Lightgun

@bc320 said in Pi4 and libreELEC: Is there a way to set up my pi so when I boot I can choose LibreElec and Kodi OR Retropie? Using something like NOOBS or PINN could help you install multiple systems on the same sdcard. is there an easy way to move between the 2? Apart from using separate cards, try option 1. if I am able to get a wireless/bluetooth controller to work with retropie will it work with LibreElec? I don't know, if it has bluetooth support built in, then it should work.

Please don't post links to rom/copyrighted material sites - https://retropie.org.uk/forum/topic/2/forum-rules.

@AmigaMoreThanCLi If this is the StarTech.com USB to M.2 SATA Converter, it only supports SATA M.2 drives. Samsung EVO 970 Plus is an NVMe drive. It will never work in this board. You need a SATA M.2 drive.

@RonsterMonster There is no official image. At the moment, you can clone the repo, but it's different from what ETA Prime did. Install raspbian lite. Install Git. Then type: git clone --branch fkms_rpi4 --depth=1 https://github.com/RetroPie/RetroPie-Setup.git Enable the GL (Fake KMS) driver in raspi-config If you're not familiar with a manual install, go here: https://github.com/RetroPie/RetroPie-Setup/wiki/Manual-Installation I'd really hope for test images soon. Basically all the libretro emulators work. The rest are hit or miss.

Thanks for the advice guys. I'll look around for a nice looking case with a quiet fan.

@steptoe that is awesome, thanks so much for this!

I have recently noticed that Flycast allows the internal resolution to be increased on Dreamcast games. Has anyone experimented with that on the Pi4 Is there a Flycast core that can emulate WinCE games? If so what is the current experience with that on a Pi4?

@jpuli004 Do a manual install on raspbian lite buster: https://github.com/RetroPie/RetroPie-Setup/wiki/Manual-Installation When you get to cloning the repo, use this instead: git clone --branch fkms_rpi4 --depth=1 https://github.com/RetroPie/RetroPie-Setup.git It's a wip, so expect bugs.

@thelostsoul Freu mich schon drauf. :)

@ksuquix since there is no official release of Retropie for the Pi4 yet, I doubt you are going to get much tech support at this time.
