Zero Team (set 3, Japan? (later batteryless)) is another version of the arcade game Zero Team. The 'batteryless' designation might indicate a change in the game's internal hardware or a removal of a battery-backed memory component. The lack of emulated protection may imply that the protection method used was unique to the game's original hardware and hasn't been overcome by emulation techniques.
