Instruction manual included. Cards are not included. Both the outer and inner boxes show signs of wear and tear due to age, but the software appears to be in good condition, so I have rated it as "Slightly scratched or dirty." Operation has been confirmed, but since it is an old item, it may not work depending on the condition of your game console. It worked fine on my game console, so I believe there are no issues with the software itself. Please understand that this is a used item, examine the photos carefully, and consider purchasing only if you are satisfied. To prevent issues such as product substitution, returns are not accepted after purchase. Please be aware of this. I can add more photos or answer any questions, so please comment. #GameBoyAdvance #YuGiOh #DuelMonsters
