Championship Bowling (チャンピオンシップボーリング, Chanpionshippu Bōringu?) is a bowling video game developed by Romstar in 1989 for the arcade and Nintendo Entertainment System. It was one of the few games that supported the Four Score accessory for the NES, allowing for four people to play. The object of the game is the same as a regular game of bowling; score the highest to win. The game utilizes factors such as left or right-handedness, spin, power, and weight of the ball, which can affect the outcome of a throw.

Championship Lode Runner (チャンピオンシップロードランナー, Chanpionshippu Rodo Ranna) is the champion's version of Lode Runner and its sequel. The game may also be found on a pirate NES cartridge under the names Super Load Runner or Load Runner 2. This game shares the same status with the Ultima and Wizardry games which had sizeable spin-offs in Japan that were mostly unknown in North America. Far more Lode Runner games were released in Japan than there were in North America. Expect a very long game with either this or any other game in the Lode Runner series.

Chaos World (カオスワールド) is a role-playing video game/strategy game for the Nintendo Family Computer created by Natsume, and released in Japan on October 25, 1991.
