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.

Code Name: Viper, originally released as Ningen Heiki Dead Fox (人間兵器デッドフォックス?), is a side-scrolling action game released by Capcom in 1990 for the Nintendo Entertainment System. The player takes control of a special forces operative who must combat a drug syndicate in South America.

Deadly Towers is an action role-playing video game developed by Lenar and exclusively-licensed by Irem as a software title for the Nintendo Entertainment System (NES). It was released in Japan on December 15, 1986, and in North America in September of the following year. One of the earliest published role-playing video games for the NES in North America, Deadly Towers was a best-selling title in 1987. In Japan, Deadly Towers was titled Mashō (魔鐘), literally meaning "Evil Bell". It is a pun of the word mashō (魔性), meaning "devilishness", and in keeping with this theme, the Japanese cartridge contained a red LED at the top which illuminated when turned on. Irem intended the game's English-language title to be Hell's Bells, but Nintendo of America refused to issue the game a Nintendo Seal of Quality unless Brøderbund changed the name.
