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.

Notes on how to set up a new Ubuntu LTS x64 environment, how to build a recent Mainline Kernel and place it on a Raspberry Pi OS SD card.
- Install tools needed:
$ apt install git make gcc g++ device-tree-compiler bc bison flex libssl-dev libncurses-dev python3-ply python3-git libgmp3-dev libmpc-dev
On systems with UEFI Secure Boot enabled, recent Linux kernels will only load signed modules, so it's about time DKMS grew the capability to sign modules it's building.
These scripts are extended and scriptified variants of https://computerlinguist.org/make-dkms-sign-kernel-modules-for-secure-boot-on-ubuntu-1604.html and https://askubuntu.com/questions/760671/could-not-load-vboxdrv-after-upgrade-to-ubuntu-16-04-and-i-want-to-keep-secur/768310#768310 and add some error checking, a passphrase around your signing key, and support for compressed modules.
dkms-sign-module is a wrapper for the more generic sign-modules which can also be used outside of DKMS.
- Create a directory under
/root, say/root/module-signing, put the three scripts below in there and make them executable:chmod u+x one-time-setup sign-modules dkms-sign-module

This guide likely applies to other models and, potentially, even laptops from other OEMs that have NVME drives. However, I've only tested this on my Dell XPS 15 (9560) with the OEM Windows installation from the Signature Edition model.
Switching from RAID to AHCI is significantly simpler than switching from AHCI to RAID. All that's needed is a successful boot to Safe Mode.
- To set the default boot mode to Safe Mode, use
msconfig.exeor open an admin cmd/PowerShell window and run:
