Kingdom Hearts Cheats (Playstation 2)

How to beat Riku
Riku will do a flying kick after 4 hits, dodge it because it does major damage to you!
Then make sure not to fall off the ramp otherwise you will lose the match if you do.

How to beat Sephiroth
In the colisuem (the platinum match), you have to face the almighty Sephiroth, harder than the final boss.
Equip Strike Raid and the Oathkeeper Keyblade. Cast the shield and use Strike Raid when ever you can. Once his life starts to go down, he uses his angel attack which drains all Hp and Mp. Stop him before he uses it.
Further down the line he will power up and go ballistic. Just keep your life up and use Strike Raid and DO NOT LET HIM USE THE ANGEL ATTACK OR YOUR DEAD.
