try beating it without a memory card and after you do, turn off your ps2. When you turn it on again and select Load game you get to see a secret movie about Xemnas and Riku.
sora is trying to find his lost memory's
If my memory is correct I believe you go back to Jaq.
In order to use any kingdom hearts codes, you need a Gameshark. You can buy one at Wal-Mart where memory cards are sold.
You only get to fight Ansem and his Guardian in Kingdom Hearts and Kingdom Hearts Chain of Memories, while playing as Riku. However, you see the Guardian again when Riku unleashes his darkness to beat Roxas in Memory's Skyscraper.
Kingdom Hearts Chain of Memories is an extra game that is about the story between Kingdom Hearts and Kingdom Hearts II. It's a game based on how Sora must retrieve his scattered memories. I hope this helped. The game is set in an old castle, which makes u lose ur memory the more further u go inside. No more info! play for urself now
Towards the end of the game, you automatically fight Roxas in front of Memory Skyscraper.
The keyblades stand for each of the worlds Sora visit or a memory of Sora's.
SPOILER Because Namine has to put his memory back together.
first of all he was not killed he was knocked out and he lost all of his memory of the organization and what happened was riku used the dark corridors to take him to his own twillight town and layed him in bed that is the first 7 days in kh2 since in 358/2 you see the video of axel and roxas on the clocktower waiting for xion and it goes back to day 7 to play the game there is your answer!!!
No. After Xion tells Roxas to set the hearts free, Roxas goes to The World That Never Was, and is confronted by Riku, who defeats him by giving in to the darkness in his heart. Riku then gives Roxas to DiZ, so that DiZ may rewrite Roxas's memory. (this is also the beginning of Kingdom Hearts II)
Riku is seen with the Oblivion when Roxas fights him at Memory's Skyscraper in Kingdom Hearts 358/2 Days. He also wields the Oblivion when Sora fights him in Hollow Bastion in Kingdom Hearts 1.
Towards the end of the game, you automatically fight Roxas in front of Memory Skyscraper.
