Deception IV: The Nightmare Princess on PC
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.exe. Pick the game folder (and its update and DLC folders, if you have
   them) and where your saves go, then press Install.
   It prepares the game from your dump (a few seconds) and offers a desktop shortcut.
2. Press Play Game, or later start deception.exe or the shortcut.

Run deception-setup.exe 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 Windows 10/11 x64, a CPU with AVX and a GPU with Vulkan 1.3.
