There are already two doujin soft for Nintendo DS dedicated to (Vocaloid 2) Natsune Miku. These DS homebrews has been released during Vocaloid M@ster event held last saturday in Tokyo. One is Mikutsun Vol.1 and one is DS Miku. 
This is a preview video shooted a month ago when Miku Stun has been spotted in Akibao (a famous underground shop in Akihabara).  To run these homebrews on your DS you need R4 or our supoer favourite NeoFlash MK5. 

I was looking for something "special" for my (cosplayer) girlfriend and I found these game costumes inspired by PacMan/Ms PacMan: I love the ghost pants and the deep blue color choice is genial (in the game the 4 ghoosts, Blinky, Pinky, Inky and Clyde, turn deep blue after pacman eats a  power pill that gives him temporary ability to eat them)! Whats better for a retrogamer girl love night?!  Waka, waka, waka....
