Retropie 4 on dietpi binary install // need short help

[jhny]

Hello,
Can someone please explain to me briefly and concisely how to set up the packages via !!Binary!! in ./retropie_setup? Installed?

Thanks

DietPi is not supported on a Pi, only RaspiOS is supported. If the binary installation doesn't show up, that's most likely the reason.

How to install Retropie on a Pi4 in Dietpi (buster)

#For those who are interested, don't know, or have had trouble installing RetroPie on a Pi4 in DietPie themselves this article might be useful .-- I spent a lot of time trying to find this solution.

#DietPi uses less resources and therefore has a good performance and is best suited for RetroGaming (RetroPie).

#Start with a fresh installation of Dietpi (in this case codename "buster" on a Pi4).

#After the installation of Dietpi.

#Create user -- you can also take the user dietpi but for overview I would create a new user, don't install RetroPie under root.

sudo adduser <username>

#Add user to sudoers group for gambling.

sudo usermod -aG sudo <username>

#Login with

<username>

#Edit config command at the end -- this is the essential part, nothing works without this setting.

sudo nano /boot/config.txt

dtoverlay=vc4-kms-v3d

#Shutdown Pi -- do not reboot but shutdown.
sudo shutdown now

#Install ALSA + Xorg + build-essential + git.

sudo dietpi-software install 5 6 16 17

#RetroPie get packages.

git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git

#Change to the directory.

cd RetroPie setup

#RetroPie Setup and install Retropie via "Binaries" modules / packages -- via Source it won't work with Dietpi.
Then run Basic Install.
You can also install the packages individually, first the dependency packages, then the core packages and then the remaining desired packages.

sudo ./retropie_setup.sh

#Finally, raspi-config must also be installed.

sudo apt-get install raspi-config

#Start Retropie.

emulationstation

#What is dtoverlay=vc4-kms-v3d?

#The entry dtoverlay=vc4-kms-v3d activates a relatively new graphics driver from the Linux kernel.

#If you are interested in this article or if you installed RetroPie with this tutorial I would be happy if you share a comment here if it worked for you.

Does it use less resources than a Raspi OS Lite ? Did you compare the performance with a stock RetroPie install (the image we have on https://retropie.org.uk/download) ?

If I use the Retropie under DietPi, I almost always get 100% 30 - 60 fps with a Full HD resolution. In my experience, this is not possible with a standard RetroPie installation from https://retropie.org.uk/download). If so, I'd like to know how. :D

So, 90% of the time, it works every time ?

You'll have to be more specific - are you talking about the front-end (EmulationStation), emulators in general or certain emulated systems ?

EDIT: one possible difference between the systems would be:

• DietPi using a 64bit system
• DietPi using -by default - the KMS driver (without the firmware layer - FKMS) that the RaspiOS buster had as a default.

Yes, everytime. :D

I meant both.
