How to install Homebrew package manager on Steam Deck

(See also installing Distroboxm, which is included in SteamOS 3.5 and newer: https://distrobox.it/ )

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

We can make this file beautiful and searchable if this error is corrected: It looks like row 9 should actually have 4 columns, instead of 3 in line 8.

Let's have a DECKARD and PPC-IOP discussion!

The PPC-IOP is present on the SCPH-75000 and newer. This PPC-IOP has 4MB of memory available to it (for reference, older models have 2MB of IOP memory and TOOLS have 8MB of IOP memory)

TJS2 VM

TJS2 compiles the script into binary code for the virtual machine (TJS2 VM) and then executes it.
A brief description of this virtual machine is provided, as the disassembly result of this TJS2 VM code is displayed when an exception occurs or when a dump is taken.

Instruction code

The TJS2 VM is independent for each execution unit such as functions and properties, and one function does not share the instruction code space, register space, flags, and constant area with other functions.
The instruction pointer (ip) always starts from 0 at the head of a function or the like.
A mnemonic is a simple human-readable name for an instruction code.
