This is “Pewter City” from the Nintendo game “Pokémon HeartGold/SoulSilver”.
The bossa nova style has not changed since “Pokémon Gold/Silver”, but for example, the chord in the 12th bar of the score has been changed from IIm7 to bII7 (Tritone Substitution of V7), giving it a more jazzy feel.
The closing chord is add9, which adds a little more complexity to the sound.
Key points of the guitar playing:
It’s important to keep the bossa nova rhythm, so if you’re not used to it, it’s a good idea to practice the intro repeatedly.
