I recommend using the video below by WING LEE on Youtube, With the info below This will set you up for 3 of the 4 Ending Achievements.
Basically you wanna start by dedicating your playthrough towards.. But Leave the Last Shop Item that you need, Then leave the game running until your file is at 4 hours and SAVE, Then finish the game for Ending 1
Go back to that same save that you saved after 4 hours of playtime, But this time Grab The Last Item from the shop you need and then finish Game for Ending 2
Ending 4 its it's own playthrough by it self.
