This is "Pop'n Music Portable" for the PSP. It's a mode where you can play your favorite songs freely using the basic Pop'n gameplay. The rules of Pop'n are simple! When the "Pop-kun" falling from the top of the screen overlaps the red line at the bottom, press the corresponding button at the right timing! In this mode, you can choose to play with 5, 7, or 9 buttons. The player can choose to be Mimi or Nyami... How about it for those who like rhythm games? #KONAMI #VP058-J1 #Entertainment/Hobbies #Game Software/Game Console Body #Portable Game Software
