Kousoku Card Battle: Card Hero Codes and Passwords (DS)

Kousoku Card Battle: Card Hero (High Speed Card Battle: Card Hero) is a card battle RPG developed by Intelligent Systems and published by Nintendo for the Nintendo DS. It is the successor of the Japan-only Nintendo Game Boy Color title, Trade & Battle: Card Hero. It was released in Japan on December 20, 2007, but there has been no word as to whether or not that it will be released anywhere else. The Nintendo DS (sometimes abbreviated NDS or DS) is a handheld game console developed and manufactured by Nintendo. It was released in 2004 in Canada, U.S., and Japan. The console features a clamshell design, similar to the Game Boy Advance SP, with two LCD screens inside - one of which is a touchscreen.

The Nintendo DS also features a built-in microphone and supports wireless IEEE 802.11 (Wi-Fi) standards, allowing players to interact with each other within short range (10-30 m, depending on conditions) or online with the Nintendo Wi-Fi Connection service, which launched later in the console's lifespan. This was the first Nintendo game console to be released in North America prior to Japan. The system's code name was Nitro, and this can be seen in the model codes that appear on the unit. The console's name officially refers to "Developers' System", in reference to the new game design the system was meant to inspire, and "Dual Screen", the system's most obvious feature. (Wikipedia)
