Where the Heart Lies Trophy in Kingdom Hearts 358/2 Days HD

For these trophies, you must simply watch all of the chapters in the game. You could select "Play" on the main menu to autoplay all of the chapters, however, there is no option to skip in the start menu. If you want to skim through all the chapters quickly, select Chapters in the main menu and select the first chapter. From here press and skip to the next chapter repeatedly.

After you have watched all of the chapters and exit back out to the Chapter select screen, all 3 trophies will unlock. Every chapter that you have viewed will be highlighted in blue.
