Pokémon turns 20 this year, and to mark the occassion Game Freak's Junichi Masuda has posted a video online in which he shares some of his strongest memories regarding the creation of this iconic series.

Masuda - who served as a programmer on Pokémon Red and Green and created the music and sound effects - reveals that the fragile and unreliable development hardware of the period created numerous headaches for the team, and that faulty PCs very nearly scuppered the project:

I remember my computers always overheating and breaking down on me.

I would work hard to fix them, and eventually we managed to complete the first Pokémon games, but I think I went through three or four computers by the end. I sure am glad I fixed those computers back then. If I hadn't, the original Red and Green games might never have come out! That's a scary thought!

These days, computers are a lot more durable, but I have a lot of memories like that from the early days.

Nintendo is launching the first Pokémon titles on the 3DS Virtual Console this month.
