How to install Homebrew package manager on Steam Deck

(See also installing Distrobox: https://distrobox.it/ )
(See also installing Nix package manager: https://determinate.systems/posts/nix-on-the-steam-deck )

You can install Homebrew (a package manager for macOS and Linux) without disabling the read-only partition with sudo steamos-readonly disable.
The package manager can be used alongside Flatpaks. Some software is only available on Flathub, and some software is only available on Homebrew.

1. Switch to desktop mode (hold power button until a menu appears, then select "Switch to desktop mode")
2. Click the logo at the bottom left, go to System, then go to Konsole

Here's a contest for OSDSYS/BIOS/ROM/Menu permissively licensed assets.
The voting page will go up once enough submissions are made.
The goal of this contest is to select the best assets for a brand new OSDSYS program, which will be launched from a Memory Card (using the exploited Memory Card Update feature of the original OSDSYS) or from a brand new ROM reimplementation.
All assets submitted must be licensed under a permissive license such as Apache, BSD, MIT, CC0, etc.
Please submit your own original works, not those copied or modified from the original ROM.
Feel free to submit assets in the format that you prefer.
Also, feel free to submit short descriptions for each asset that does not have a description. For icon/3D assets, try uploading in the PS2 icon format, but if you can't, upload the original project file along with the name of the software that you are using so I can take a crack at it.
For image assets, try uploading in the PNG format.
For audio assets, any format that is readable

OSDSYS image resource image information

The information in this documentation does not apply to the early Protokernel consoles which has a very different OSDSYS program.

The images stored in the ROM are in a compressed format, so decompress before use. The following is the implementation of the decompression routine: https://gist.github.com/uyjulian/14388e84b008a6433aa805f5d0436c87

The images stored in the ROM are raw image formats with no information attached, so the following table describes the extra information required to display the image.

| Filename | Size | Offset | Image format |
