Nihon Falcom
All of these early soundtracks were produced using the FM synthesis sound chip of the PC-8801. Despite later advances in audio technology, Koshiro would continue to use older PC-8801 hardware to produce many of his later video game soundtracks, including the "Streets of Rage" and "Etrian Odyssey" soundtracks. His soundtracks for early Nihon Falcom games, such as the "Dragon Slayer" and "Ys" series, are widely regarded as some of the most influential role-playing video game scores.
