How to install a GNU/Linux ARM emulator

Prerequisites:

• A PC with a Linux distribution - Arch Linux amd64 used here

Dependencies (for Arch Linux amd64 but very easy to get on most distros):

• edk2-armvirt (or a prebuilt firmware binary from the Unofficial EDK2 nightly build project [some builds may have issues, here's a direct link to a build I confirmed to work])
• qemu-arch-extra (provides the command qemu-system-aarch64)
• wget (or any downloader)

How to record or stream SteamOS 3.X in gamescope (Gaming Mode)

Here is another method that uses Flatpak and obs-vkcapture, which don't meet my personal needs but are very likely to be useful for you. In the comments there there is also an obs-gstreamer method.

Here is another method for recording that has its own GUI for Gaming Mode built with Decky Loader.

Force SteamOS to behave very much like Arch Linux

Key phrase: very much like, not identical. Always treat this as more unstable than Manjaro and only expect support with it in my comments section here.

1. Set a password (if you haven't already) and disable read-only rootfs (yes this means after updating SteamOS [not Steam Client] this will all be deleted and you will have to do all this again if you want
