Unlocking all cards in the Yu-Gi-Oh! Power of Chaos trilogy (Yugi the Destiny, Kaiba the Revenge, and Joey the Passion) typically requires manipulating the game's Registry entries and its system.dat save file. 1. The Registry Key Fix (Modern Windows) The game stores card progress in the Windows Registry. If you are on a 64-bit version of Windows (Windows 10/11), the path is often redirected to a "Wow6432Node". Registry Path: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KONAMI\Yu-Gi-Oh! Power Of Chaos\system . Key Action: Look for the flcrc binary value. This hex representation is directly linked to your collection progress. Fixing Save Locations: Ensure the CommonDir entry in the registry points exactly to your "Common" folder (e.g., C:\Games\Yu-Gi-Oh! Power of Chaos Common ). 2. The "system.dat" File Method The game uses a file called system.dat to track which cards you've earned. Quick Cheat: Some versions of the game include a system.full.dat file in the installation folder. Renaming this file to system.dat and replacing the existing one in your "Save" or "Common" folder can instantly unlock the full card list (155 for Yugi, 315 for Kaiba, and 350 for Joey). Merging Games: To see all cards from all three games, you must launch Joey the Passion and ensure it is looking at the shared "Common" directory where the other games' save data is stored. 3. Automated Unlockers and Mods For a more updated approach (as of late 2024–early 2026), several community tools simplify this process:
