twinbrat: MAME ROM Information.


Twin Brats (c) 1995 Elettronica Video-Games.

This game is "Ladybug" with more stylish graphics and pictures of naked women between the racks. Like "Mad Donna", it takes the completion of two racks to see the naked lady picture, unlike Mad Donna completing the first (odd numbered) rack will give you the picture obscured by a pattern.
