What you need: Your own extracted, plaintext Mobile Suit Gundam Battle Operation Code Fairy PS4 game folder (`CUSA28763`, with `eboot.bin`, `sce_sys/param.sfo` and `sce_module/`) at version 01.03, or at 01.00 with your own matching 01.03 update PKG, and your own three volume unlock-key PKGs. 64-bit Linux (tested on Fedora).

Gundam Code Fairy PS4RT is a game-specific compatibility runtime by HekamiAeon that runs Mobile Suit Gundam Battle Operation Code Fairy, Bandai Namco's 2021 PS4 game, on Linux. It prepares and runs the game's original x86-64 code on the PC, supplies its own versions of the PS4 services the game needs, and draws with a Vulkan renderer derived from shadPS4. It is not a general PS4 emulator or a recreation of the game, and it has been developed and played on Fedora.

Code Fairy is episodic: its three volumes are already in the game and are opened by three unlock-key packages, which the player needs as well as the game itself at version 01.03. No game files, firmware, packages, keys or saves are supplied, and the runtime doesn't get around the volume locks. The portable release includes its own installer for the update and the keys.

A Windows build of this runtime is published separately by DiamondDogz as Gundam Code Fairy PS4RT for Windows, also listed here.

## How to set it up

1. Download the Linux `.tar.gz` (not the source archive) and extract it.
2. Open a terminal in the extracted folder and run `bash Play-Game.sh --game "/path/to/CUSA28763"`, pointing at the `CUSA28763` folder itself.
3. If your game is 01.00, the built-in installer applies your own 01.03 update PKG first. It changes that folder in place, so back it up if you need the original.
4. Install the three volume keys when it offers, or later with Install DLC... in the Graphics overlay. After the first setup, later starts need only `bash Play-Game.sh`.
