Wisdom Tree is a Christian gaming company originally called Color Dreams. They basically took some of their Color Dreams games and added Bible themes. These games didn't just rip off their own games. Eventually, Nintendo found out about all these games being made without their permission. When the SNES was released, they installed a lockout chip allowing only licensed games to play. Wisdom Tree got around this by creating the Wolfenstien clone, Super Noah's Ark 3D. by inserting a licensed game into the top of it, it overrode the lockout chip.
