DivaScript

DivaScript (commonly referred to as DSC) is the file format used by all the Project DIVA games for storing various commands related to Music Videos/PVs and Rhythm Game Charts.

The data inside .dsc files is stored in a binary format. This means that they can not be edited with a text editor and instead require specialized programs that can decode them such as DSC Studio or ScriptEditor. Additionally, .dsc files from Project DIVA F2nd and Project DIVA X are encrypted using DIVAFILE encryption. They need to be decrypted before editing.

DSC Formats

Every Project DIVA game uses a specific DivaScript format. The exact format of a .dsc file is determined by the first 4 bytes of the file.
