Ultra Sun And Moon Shouts Out The Time Iwata Helped Save Pokemon

Last week, fans discovered that the latest Pokemon games reference beloved Nintendo CEO Satoru Iwata, who died in 2015. The Easter egg is touching, but it’s also kind of brief. Here’s the full story behind how Iwata saved Pokemon – and a closer look at why the man became so legendary.

Joe Merrick, proprietor of Pokemon site Serebii, shared images of a moment you can experience on Ultra Sun and Moon on Twitter earlier this month:

The exchange, which happens in the virtual Game Freak offices located in Ultra Sun and Moon‘s Heahea City, can only be experienced if you happen to be holding a monster from the 3DS’ virtual console. (In this case, it’s Pokemon Silver.) If you meet those requirements, a character can say the following to you:

Boy, when we were told halfway through development to make Kanto, too…

I thought I might just expire on the spot! But I’m glad we made it that way.

When we were having trouble fitting all the data in for Gold and Silver, and we were really in a pinch, this amazing guy came along and made a program for us that solved all our problems. He went on to become the amazing president of a real big company soon after that, too.

That amazing guy is of course Iwata. Some of you may have heard this story already, but here it is for those of you who haven’t. Infamously, Pokemon Gold and Silver had a troubled development cycle. At the time, Game Freak, the developers, literally only had four programmers working on one of the biggest gaming franchises in the world. Naturally, the team wanted to make the games as ambitious as possible, which only added to the strain. Making things worse, the explosive popularity of the franchise also meant that Game Freak had to find a way to port the original Red and Green to America, something that threatened to push the release of Gold and Silver even further. The other big wrench in the mix was that, midway through development, Game Freak apparently had to add another region to the game – and they hadn’t planned for that. Actually, they had no idea how to make it all fit onto a Game Boy cartridge. It was a mess.

Enter Iwata, who helped devise a way for Game Freak to fit all the code onto the cartridge. Here’s how he recounts the tale, per an older Iwata Asks interview with Tsunekazu Ishihara of The Pokemon Company and Shigeki Morimoto from Game Freak:

Iwata: Although I wasn’t working for Nintendo at that stage, I ended up acting as a go-between for Nintendo and you for some reason. (laughs)

Ishihara: That’s right.

Iwata: At that time I wasn’t a Nintendo employee but was President of HAL Laboratory. At the same time, I was a board member at Creatures Inc. and I ended up being involved in analysing the best way to localise the overseas versions of Pokemon Red and Pokemon Green. For that reason, I got hold of the source code for Pokemon Red and Pokemon Green and I would study that and suggest ways to localise it to the relevant department at Nintendo.

Ishihara: At the same time, Pokemon Stadium16 came out…

Iwata: Right. (laughs) You decided to release Pokemon Stadium for the Nintendo 64 and the first task was to analyse the Pokemon Red and Pokemon Green battle logic and send it over to Miyamoto-san and his team. You’d normally expect there to be a specification document, but there was nothing of the sort…

Morimoto: I’m so sorry! (laughs)

Iwata: No, no, it’s fine! (laughs) Studying the program for the Pokemon battle system was part of my job.

Morimoto: I created that battle program and it really took a long time to put together. But when I heard that Iwata-san had been able to port it over in about a week and that it was already working… Well, I thought: “What kind of company president is this!?”(laughs)

All: (laughter)

Morimoto: I was saying things like: “Is that guy a programmer? Or is he the President?”(laughs)

Iwata: To be blunt, at the time I was more of a programmer than I was a company president. (laughs)

Morimoto: (laughs) I was really taken aback that you could get to grips with such a complicated program in such a short space of time.

Ishihara: I remember thinking that there just weren’t that many people out there who would be able to read the entire Game Boy source code, which was by no means written in a highly-refined programming language, and grasp how everything connected with everything else. So Iwata-san, you analysed the whole thing and reworked the code, decided on the way to localise Pokemon Red and Pokemon Green, got the battle system running on N64… I was surprised that you managed all of that…

Iwata: Well at that time, I felt that for the whole team at Nintendo, the biggest priority was not to do anything that would adversely influence the development of Pokemon Gold and Pokemon Silver. So I very naturally slotted in on the development side for Pokemon.

Morimoto: What’s more, there were the tools for compressing the Pokemon graphic code…

Iwata: Ah yes, the compression tools.

Morimoto: You were kind enough to create those tools.

Iwata: Yes. (laughs) Well, I had heard from Ishihara-san that you’d been rather concerned about it.

Morimoto: At that point, we got a little carried away and were making all sorts of demands, saying: “This part isn’t quite right – do you think you could fix it?” We had some nerve to be making those requests to a company president… (laughs)

Iwata: Well, I was willing to do whatever I could! (laughs)

Ishihara: It would have been a waste to just have you as President! (laughs)

All: (laughs)

Iwata: Being able to participate in that small way in Pokemon, I came to feel a real affinity for the software. In any case, while it was tough going, Pokemon Gold and Pokemon Silver were successfully released.

Ishihara: I remember that when Pokemon Gold and Pokemon Silver were released, I felt like a burden had finally been lifted from my shoulders. We’d had our sights set on the finish line of Pokemon Gold and Pokemon Silver for so long, and now that we’d finally completed the major series running right through from Pokemon Red and Pokemon Blue, I felt I could say to Tajiri-san: “I’ve fulfilled my duty!”

Just one of many examples of Iwata’s programming brilliance. What a guy.

Over at Serebii, you can read a catalogue of the other trivia facts you can learn at the Game Freak offices. Did you know, for example, that the save sound is slightly different depending on what version of Pokemon you’re playing?


  • Playing Gold/Silver before the internet was really around was a fantastic experience. No spoilers and discovering things for yourself. Then once you finished beating the elite four there’s an entire other region to explore. Absolutely incredible.

    PS also challenging Red was awesome.

    • Yeah seriously that game was pinnacle of the series for me. Mainly for the fact like you stated internet wasn’t really a thing and that little surprise at the end was like WTF I get another region to explore was just golden cookie crumbs on the delicious sundae that was Pokemon Gold. Ps Tyranitar LOL.

  • The guy might have arguably made some missteps from a “dead inside” shareholder perspective, but he was a truly inspirational CEO with a deep understanding and love of his craft.

    Ah dammit, there’s something in my eye again…

  • Playing Gold/Silver as a kid made me assume that every Pokemon after would have an old region in it. Little did I know how special that was!
