To understand the Sonic CD Soundfont , you must first understand the game’s controversial audio history. Sonic CD is unique because it shipped with two completely different soundtracks.

In 2010, a more comprehensive soundfont was created by a user named "ZeroG" (real name: not publicly known), which included a vast majority of the game's sound effects and music samples. This soundfont became widely popular among music producers and Sonic CD fans.
