This is a DIG DUG in PSX Namco Museum Vol.3(Japan).
Made as a SuperPlay.
DIG Achievement with 8 enemies alive in ROUND 9.
Masterjun: Judging.
Masterjun: The goal of "DIG Achievement with 8 enemies" is arbitrary and does not make for an entertaining movie. This game repeats after 12 rounds. You only play to round 9, thus, this run doesn't complete the game.
Rejected.
