This is a beta version of Secret Scout in the Temple of Demise, an unlicensed NES game. As a beta, it indicates an unfinished stage of development before the game's potential official (or unofficial) release. The differences between this and the released version could include altered gameplay mechanics, different graphics, incomplete level design, or the absence of features present in the final product. Its status as an unlicensed, beta version adds to the scarcity and interest of the game for collectors and retro gaming enthusiasts. The developer and publisher information is most likely missing given its unlicensed and beta status, making researching the history quite challenging.
