Unlocking all cards in Yu-Gi-Oh! Power of Chaos typically involves modifying the game's registry and replacing the system.dat file located in the game's "Common" folder. Because the game is an older title, manual methods are often preferred over standard gameplay, which requires winning hundreds of duels to collect the full 771-card set. Common Method to Unlock All Cards
The most reliable way to unlock all cards is to use a "Common" folder hack that bypasses the long grind:
Download an Unlocker/Save File: You will need a system.dat file that already has 100% completion and an accompanying .reg (registry) file.
Locate the Common Folder: Place the system.dat file into the Yu-Gi-Oh! Power of Chaos Common directory.
