1. Open the Yu-Gi-Oh! Power of Chaos Common folder.
2. Copy any decks you want (.ydc files) along with system.dat and place them in the Yu-Gi-Oh! Power of Chaos Common folder on the target PC (Overwrite if necessary). If it does not exist there, make sure to launch the game at least once or search for the folder, in case it was created somewhere else.
3. Edit the registry.

• Find the game's registry entry. Default: HKEY_LOCAL_MACHINESOFTWAREKONAMIYu-Gi-Oh! Power Of Chaossystem
• flcrc contains a hex representation related to the game progress.
• CommonDir contains the path to the game's common folder.
• Search for the game's registry entry on the target PC.
• Either edit the flcrc key manually to match the one of your source PC, or create a .reg file on your source PC by rightclicking on the system folder and choosing 'Export' and open it up on your target PC to automatically add the registry key. Bear in mind that the CommonDir may differ however, depending on your installation path, so you may have to modify the path after all.
