Early video game streaming was analog, sourced from a cassette tape inside an arcade cabinet.
Currently, many arcade game platforms are based either on similar home-console technology, or general purpose computers using x86 architecture.
With their increased storage size over previous media such as cartridges, streaming audio and video could be added to games.
Some of the earliest examples of Mixed Mode CD audio in video games was the Ys series, composed by Yuzo Koshiro and Mieko Ishikawa, and arranged by Ryo Yonemitsu for the PC Engine from 1989.
It wasn't until Creative Labs's Sound Blaster series, introduced in 1989, that PCs became capable of playing back pre-recorded audio.
