Setting up RetroArch on Raspberry Pi 4 and building emulator cores

Guide for myself and others to get RetroArch running on the new Raspberry Pi 4 while projects like RetroPie get an image out for the rpi4.
Disclaimer: I am not an expert and this may not be the most optimal build possible, but it works.

Inspiration taken from:

• This gist showing the basic steps for building and configuring for raspberry pi 3. I'm new to Raspberry Pi and RetroArch myself so this was super helpful and I recommend looking through it.

• This Reddit post showing the performanc gains over the pi 3b+

Add on top of default.nix: with import {}; or simply run as nix-build '' (i. e. for nix-build complaining) or rather nix-build -E 'with import {}; callPackage ./default.nix {}' (or even import)

Run this in order to backup all you k8s cluster data. It will be saved in a folder bkp. To restore the cluster, you can run kubectl apply -f bkp.

Please note: this recovers all resources correctly, including dynamically generated PV's. However, it will not recover ELB endpoints. You will need to update any DNS entries manually, and manually remove the old ELB's.

Please note: This has not been tested with all resource types. Supported resource types include:

• services
• replicationcontrollers
• secrets
• deployments
• horizontal pod autoscalers

// This is a basic example of running an nsqd instance embedded. It creates
// and runs an nsqd with all of the default options, and then produces
// and consumes a single message. You are probably better off running a
// standalone instance, but embedding it can simplify deployment and is
// useful in testing.
