WiiWare is officially back in Japan, with one of the most content-rich updates we'd ever seen. Just Castlevania: The Adventure ReBirth would be enough to make this week remarkable, but Game Arts' Shadow Walker and Bit.Trip VOID are available as well, along with an oddity from D3!

Not enough? How about four Virtual Console games, including a Sonic & Knuckles with the lock-on feature intact? Or a budget DSiWare game about blowing up asteroids to save the Earth?
