KH Shadow Galaxy X game discussion : kingdom hearts 1 very odd cheat codes

ok first of all, i found 15 codes for this game but all of these codes froze the game somehow... and they are: sora- gets BIG HONG KEY- ok this just puts a empty slot in weapons but this be the code- FEBFDD0C BCA99B84. if anyone can make it work.. thx dood! oh yeah... 2 codes- 04d0342a 14b45778- max accessories - 04d0342a 94b477e8- max items.. p.s someone said sora has 12 item and accessory slots and if you put a final mix code in backwards.. it works... huh? e.g: 11111111 22222222- fm/ 22222222 11111111 english game... ???
