The official Pokémon Sound Library website now offers the original soundtracks of Pokémon Red and Green, thanks to the generosity of Nintendo and Game Freak. Altough unfortunately, the website is currently restricted to Asia. To access the 45 tracks from the games, you must either use a VPN or visit the Japanese Pokemon channel on Youtube, which has combined all the tracks into a single video. Click the link to listen to the Pokémon Red and Green soundtrack and immerse yourself in the nostalgic sounds of simpler times.
