I need some help if anyone has experienced or tried this on Chrono Cross

??? I need some help if anyone here in the forums has experienced this or tried this on the game chrono cross. Whats happening is i have used an unlock all characters code. said code being:800719A0 FFFF
800719A2 FFFF
800719A4 FFFFI'm using this code when starting a new game but every time without fail when i get to ther other world and try to talk to Leena she just clams up. Theres no moving the game or story forward no nothing. Without using the code the game works fine. Has anyone experienced or tried this? and if so is there a work around to get further into the game? i'm just curious. otherwise i'm gonna go with following the walkthrough.

Try saving after that point and then enable the code?

Do you mean the game freezes? Or that she won't talk to you?If I remember correctly, there is some story line between Leena and Kid when you first go to another world, and depending on what you do with those two, different things happen. By using the cheat you may be messing up the game.
