Zellers entered the video game market by selling a line of rebranded, unlicensed Atari 2600 cartridges in Canada. Their library featured clones and local releases of popular titles, including Frontline, Space Adventure, Circus, Challenge, and Defender. These games were packaged in distinctive Zellers-branded boxes and cartridges, making them unique collector's items today.
During the early 1980s, the retail chain sourced its software catalog from international manufacturers who duplicated existing software code. Among these releases,
Frontline (1977) and
Combat (1977)—including the rare
Combat [Text # Side Label] (1977) variation—repackaged early military-themed shooter gameplay for the Canadian market. Similarly,
Space Adventure (1977) offered localized access to early science-fiction action.
The publisher also targeted popular arcade ports.
Circus (1978) duplicated the block-clearing mechanics of
Circus Atari (1978), while
Challenge (1980) provided simplified tactical shooting. The inclusion of
Defender (1981) in their catalog capitalized on the massive home console market for scrolling space shooters. These cartridges featured simplified plastic casings and modified label artwork that differed significantly from official Atari releases. Because distribution was strictly limited to the chain's regional department stores, these specific editions, particularly the text-labeled variants of
Combat, serve as key artifacts documenting the era of unauthorized software duplication and regional distribution networks in early console history.
