Easy Riku Defeat
Do you have trouble with the last Riku fight? In order to defeat him,be around level 70 and have about 5 "0" cards and whenever he uses the move where the room gets dark and he jumps off the walls(Dark Aura) or Dark Firaga, use them. It is important that you keep them at the end of your deck so you wont have to search your deck for them. Once you defeat him, go to destiny islands and save it and then go to Castle Oblivion and you face Larxene.
Friend Card Slight Tip
This is for the slights that require friend cards (such as Goofy, Donald, and others). For example, you have Trinity Limit. It requires Goofy, Donald, and any attack card. What you do is wait until you get a Goofy or Donald friend card. When you get it, use L + R and the same for the attack card. When you get the last friend card you need, use Trinity Limit or the other slight that you're using. You get to keep your attack card because it's not the first card for the slight!
Genie Summon Card
How to dodge good
If an enemy is attacking you, jump over him so you can hit him in the back.
Knocked Out Heartless
This isn't a code, it's just a hint. If you hit a heartless in the field, it will become knocked out in the beggining of the battle (this doesn't work on bosses!).
To play in versus mode with other Nintendo GameBoy Advance Users, you must defeat the game in Story Mode with Sora. This will also unlock the "Riku Story Mode".
Mushu summon card
Randomly found inside one of the doors opened with the golden bar card.
Reverse Rebirth Mode
Complete the game with Sora the first time through. After that, when you load a new game you will get an option for Reverse Rebirth mode, where you will control Riku.
To unlock Riku's story mode beat the story mode with Sora.
Riku's story mode
Finish the story mode with Sora.
Simba Summon Card
Defeat Guard Armor.
Skip story sequences
You can skip story sequences (dialog) by holding down start for about 2 seconds. Unfortunately, this does not work for the animated sequences.
Sora's Best keyblade
After beating Riku's story mode, go back to your story mode for Sora and use a treasure chest map card in castle Oblivian and you should get Sora's best Keyblade.
Summon Card Defeat Captain Hook.
Beat Reverse Rebirth mode to unlock Ultma Weapons for Sora. You can buy them in Moogle Shops.
Unlimited Moogle Points
For this secret open two connecting rooms, and wipe out all the enemies inside. The places were moogle points are regenerate after you leave a room and return, but the enemies don't. Just go back and forth in those two rooms to get all the moogle points you want. I find that you get about 2000 in about 5 minutes or so, depending upon how lucky you are.
White Mushrooms and a fast way to get Premium Cards
When you use a White Mushroom Map Card, you'll be in a room with alot of White Mushrooms. When you fight them, they won't attack you, so don't attack them. However, when they have a lightbulb above their head, use Thunder on them and they will die instantly and give you a Premium 65% of the time.
