Deception IV: The Nightmare Princess on PC (Linux)
Release deception-pc-v0.1-2026-11-09

You need a decrypted dump of your own copy of the PS4 game (CUSA02859): the folder with
eboot.bin, sce_module, sce_sys and FILE_PS4. Its update (version 1.01) and DLC dumps are optional;
shadPS4's <game>-patch and dlc/CUSA02859 folders work as they are. No game files are included.

1. Run deception-setup (from a file manager, or ./deception-setup in a terminal). Pick the
   game folder and where your saves go. It prepares the game from your dump (a few seconds) and
   offers an entry in your application menu (Steam's "Add a Non-Steam Game" lists it too).
   From a terminal it also takes: ./deception-setup --game <dump> [--update <folder>]
   [--dlc <folder>] [--save <folder>]
2. Start the game from the menu entry, or run ./deception.

Run deception-setup again to change the game or save folder. After unpacking a newer release
over this folder, run it once more: it keeps your folders and settings.

In the game: F10, or Select (Share/View) held for two seconds, opens the display settings (window,
resolution, VSync, sharpening); F4 asks to close the game.

settings.ini (made by the setup) holds the window, audio and control options; one in your save
folder is read instead, and the display settings save there. If the game stops, the reason is in
deception.log, in the log folder of your save folder. Shader caches are kept in the shaders
folder here.

Needs Linux x86-64 with glibc 2.39 or newer (SteamOS 3.7, Ubuntu 24.04, Debian 13, Fedora 40 or
newer), python3 3.10+ for the setup, a CPU with AVX and a GPU with a Vulkan 1.3 driver.
