Intelligent Systems

 is a Japanese video game developer best known for developing the "Fire Emblem", "Paper Mario", "WarioWare", and "Wars" series. Originally, the company was headquartered at the Nintendo Kyoto Research Center in Higashiyama-ku, Kyoto, but later moved to a building near Nintendo's main headquarters in October 2013.
History.
Intelligent Systems started out in the video game industry when programmer Toru Narihiro was hired by Nintendo to port Famicom Disk System software to the standard ROM-cartridge format that was being used outside Japan on the NES. Similarly to the origins of HAL Laboratory, the team soon became an auxiliary program unit for Nintendo that provided system tools and hired people to program, fix, or port Nintendo-developed software. Much of the team's original work consists of minor contributions to larger games developed by Nintendo R&D1 and Nintendo EAD.
Narihiro programmed his first video games, "Famicom Wars" and "", towards the end of the Famicom's life cycle, although the game design, graphic design, and music was provided by the Nintendo R&D1 team. Because of Narihiro's success, Intelligent Systems began to hire graphic designers, programmers, and musicians to extend the company from an auxiliary–tool developer to a game development group. The company continued to develop new entries in the "Wars" and "Fire Emblem" franchises.
In 2000, Intelligent Systems produced "Paper Mario" for the Nintendo 64, which ended up becoming a surprise hit, leading to five sequels being produced. Three years later, the first entry in the "WarioWare" series was released on the Game Boy Advance, and it too became a successful series.
