The Konami Game Master 2 is a sequel to the original Game Master. It supports more games, and has the addition of 8kB SRAM which can be used by select games to save progress or to save your own levels like in King's Valley II.

Unlike the original Game Master, the Game Master 2 was never officially released outside of Japan. The Japanese title is コナミの新10倍カートリッジ a contraction of コナミの新10倍楽しむカートリッジ which translates to "Konami's New cartridge to enjoy 10 times". It was released in 1987 for 5800 Yen.
