Notes

This japanese romset comes from a bootleg pcb.Rare than the original.
* Note:The sound cpu was protected inside a epoxy block fit on a 40 pin socket in reverse of cpu board (solder side).By dissolving resin the small sub pcb contains Z80A (identified by pins),76c28 (6116),a 74ls00 and 74ls138.

-Controls:
This game uses 8way joystick and one button (shot).Hardware accept inputs by other two buttons as the jamma standard,but their function is the same of first one.

** It is not total, in normal waves you die by collision with bosses shot,and with walls and enemies in cavern waves and final base. In normal waves,you cannot get special weapon objects too.
Demo sound is always active by default.Dip switch are good by testing.
Dip switch changes apart for coin settings are immediately effective (by next play and during play),no need of turn off/on power.
