Although he was not part of Nintendo at the time, Iwata helped with developing "Pokémon Gold" and "Silver" by creating compression tools used for graphics in the games. While working as a go-between for Game Freak and Nintendo, he helped program "Pokémon Stadium" for the Nintendo 64. All he had to do was read the original coding in "Pokémon Red" and "Green" and porting the battle system into the new game in just one week. Tsunekazu Ishihara, the president of The Pokémon Company, said that Iwata was important in bringing "Pokémon" to Western markets. While being president of HAL, he created the plan for localization after reviewing the code for "Red" and "Green". They were released in the West two years after they were released in Japan. He also helped Masahiro Sakurai develop "Super Smash Bros." for the Nintendo 64.
