You need to buy a memory card, buts its your choice if you wanna buy a more expensive one that has alot of space for it.
Reply:depends. You use PSP and have tons of music then yes get a big memory card. If you want to put movies and videos yes also. If you have about 1-3 games and you play it just stick with your memory card. If you have tons of games, buy middle 215 mb card. Like Dynasty warriors, you need some memory to save all that character
