Changes

Sega-CD, PC-Engine, PlayStation, Sega Saturn... what do these console 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.

Since then developers no longer use Because these mixed CDs are difficult to properly archive just by using standard .ISO files, data-dumping software will usually do one of two things as a workaround:: '''Full Dump:''' BIN/ISO + CUE:* BIN/ISO is the full disc data, including Audio-CD sound data and game data:* CUE is the datasheet file: '''Light Dump:''' ISO + MP3/WAV + CUE:* ISO is the disc data with only the game data:* MP3/WAV is the sound data from the Audio-CD, but these formats take much less disk space:* CUE is the datasheet file Developers have long since stopped using the Audio-CD format , and instead prefer custom audio formats that come included in the "game data" part of the disc. By the time the PS1 generation came, the Audio-CD part was typically just used for messages like "Don't put this in a CD player!" and little else (, although there were still a few exceptions exist, of course!).
