Hacking Dragonball Z Budokai 3 Collector Edition

[zibra]

Hi, everyone, i'm totally new to the hacking scene, i'm trying to hack budokai 3 CE for ps2 and my goal is to make the fusions between characters last until the end of a fight.
When two characters fuse themselves tthe ki bar under the energy bar change in a time-bar that decrease until the fusion break and you must gain energy again to make the supermove (fusion). I have the game and the sles file (pal game) i open it in ps2dis, invoke analyzer, but i don'y even know how to search now in the label panel.
I don't know how to find the code that refers to the fusion time to block it.
Anyone can help me?

Thanks

P.S.
sorry for my english
