Changes

PCs, Sega-CD, PC-Engine, PlayStation, Sega Saturn... what do these console systems all have in common? They all use a regular CD format! Game developers often stored music and other sounds using the Audio-CD format, but it was terribly inefficient when it comes to disc storage as it also had to store the actual game along with the sound files (commonly known as a "mixed CD"), and these sound files are never compressed because the Audio-CD standard simply doesn't allow for sound compression. To put it in perspective, a 700 MB CD containing nothing but Audio-CD data can hold at most around 80 minutes worth of sound data, meaning games that used a lot of sounds were limited in size.
