Thanks for the help everyone. I managed to get pass End of the World after doing few level grinds. The only problems I'm having now are Sephiroth and the Mysterious Figure, which we all know is Xemnas. I never beat Sephiroth in my PS2 version so I know I probably won't beat him now.
As for the difficulty I was on, it was normal and I was using the Oblivion until my friend decided that I use Rumbling Rose, which I didn't. But I was still able to beat the game. Now to go back and do it all over again on Critical and Beginner. I'll be sure to use everyone's help and tips during the Critical gameplay, that's for sure ^-^
So, while cheating to find the rest of the Dalmatians, it seems that my journal says that I'm missing numbers 46, 47, 48. Here's the thing, I already have them but it won't register in the journal, I guess.
I went to the area where the Dalmatians were supposed to be which is at the Palace Gates in Agrabah. I go there and the chest is not there. Thing is, I remember getting this chest. So...why isn't it in my journal. The chest isn't there, I remember opening it, and I even watched a youtube video to confirm it.
So...why isn't it coming up in my journal? This is probably going to stop me from getting the trophy I need. I hope it's not a glitch or something cause this is kind of making me mad.
