Kingdom Hearts II Data matches

I need help, all I want to do is fight the Data Roxas, but when I got to the place to fight the data members, his battle area wasn't there, how do I get him? Yes, I have defeated him before, the real one.

 

Just beat the game once, and save. When you return his data fight will be there, as well as some of the other data fights.

 

You can beat the game and save after the credits in this game? Wow, did not know that one. How do you unlock Terra battle?

 

Same thing, beat the game once. Then return to Disney Castle.

Oh, and I think you have to press circle after the end game statistics show.

 

On critical mode? Do you have to start a new game too? Thanks for the info by the way.

 

No, I don't think it matters what mode your playing in to unlock the ES battle.

No, the game starts back right before the final battle after you save.

And your welcome!

 

Thanks alot. Wow, and I've been trying to unlock it for like five days <_< Thanks again xD

 

Here is the whole thing!
When you finish all the original battles of Org. 13 finish the game after credits cutscene (Secret Ending) the statistics screen will show up then press O and save it to a file you want then the game will restart automatically and then you can go to Cavern Of Remembrance and find all data fights and fight Terra too!!!

 

I just kinda figured that out :\

 

Ok I just sum up the whole thing:):):):)
