Mani 4 In 1 - Gameboy Color - Compilation, Arcade

This thing here is not so strange - it's a licensed multicart, made only for the Chinese market, with four Tomy games on it: Ganbaruga, Raijinou, Zoids and Miracle Adventure of Esparks. It was actually released by Nintendo's Hong Kong distributor, Mani (although his name does not appear on the cart), along with at least one other, which contained Taito games. Presumably this was their official attempt to compete with the pirate multicarts flooding the market, but given that you hardly ever see one of these and pirates are everywhere, it seems to have had minimal success. It's interesting that Mani made it in China, since all licensed Game Boy games from other regions were made by Nintendo in Japan.
