According to the IGN Page Tengen was an Atari spinoff to create games on NES. Additionally, Tengen were labeled cartridges produced by Atari Games inc. with reverse engineered "10nes" chips in them and were unlicensed by Nintendo of America or Nintendo inc. of Japan. Atari lost in a court action bought by Nintendo of America and were forced to pull the Tengen cartridges from distribution.
