Non working rom

Hi. I like the site. It's great!. Almost all the games I've downloaded run perfectly. But Kingdom Hearts for the NDS doesn't work. When a select new game, it freezes and doesn't do anything else. Also the iso for Final Fantasy IX CD1 doesn`t work either. Can you fix it?

it is not the rom at fault.
