Mini Vaders

Taito Corporation’s Mini Vaders is a single-player shooter released in Japan during December 1990. Players use a two-way joystick to maneuver their spacecraft and a single button to fire at descending formations of miniature alien invaders. The game presents a gallery-style shooting experience, challenging the player to eliminate all enemies on screen before they reach the bottom of the playfield. The gameplay evokes classic shooter titles with its straightforward controls and escalating difficulty as waves of aliens appear. This version was initially distributed in Japan alongside test cabinets, indicating its role in evaluating hardware functionality for wider release. Mini Vaders runs on a Zilog Z80 processor operating at 4 Mhz and utilizes board number K11X0622A with prom stickers D26.
