That game is Dig Dug, the arcade game from Namco where you control "Dig Dug" (Later officially named Taizo Hori), a digger tunneling his way through the earth in order to eliminate the monsters lurking underneath its soil. He can do this by either dropping rocks on them or by inflating them until they pop. Dig Dug is 600 points because of import costs.
The other import is Bio Miracle Bokutte Upa. If you've managed to sample some of Konami's Parodius series you might know the titular character Upa - He appears in a few of them as playable character. Bio Miracle Bokutte Upa is a fun little platformer and well worth a look. It was originally released on the Famicom Disk System, then ported to the regular Famicom a few years later - This is the disk version. It costs 600 points.
