[pop'n music portable] なまいきプリンセス (EX) 

I got PSP recently to try PSP rhythm games. I'd never played PSP before because when PSP was popular, I was too young and didn't have the money to buy one.
pop'n music portable series continued the home version of pop'n music which ended with PS2 pop'n music 14 FEVER. But this game requires players to handle arcade pop'n music's chart only with PSP buttons. What an evil.
