Famicom Rocky

(from wikipedia.ja):

The main character, Yuki Todoroki, uses a variety of game techniques that he has developed himself to compete against the best players on the NES. Various tournaments are held, ranging from a neighborhood association-level tournament to a match against a secret society plotting a global conspiracy.

In the "Shogakugakusei Gosei" serialization, Yuki Todoroki plays against numerous opponents on the NES, but his opponents are different from those in the "CoroCoro Comics" serialization, and the games used in the matches are also different from those in the "CoroCoro Comics" version. Some games, such as "Super Mario Bros." In "Bessatsu Coro Coro Comic" a joint production with Kaoru Obayashi's "Radio Controll Boy" which was also serialized in the same magazine, proved the popularity of the NES and radio controller, two major hobbies of the time. This chapter was included in Tentomushi Comics' "Hero Special".
