SND file extension - Sega FILM/CPK file format
What is snd file? How to open snd files?
File type specification:
The SND file extension is used for video files in FILM/CMK format.
FILM is a multimedia container file format developed by Sega for use on its early CD-ROM home video game consoles like Sega CD, the first CD-based video game console. There are many early variations of the FILM format observed on a number of Sega CD titles. Further, early FILM files have been observed on at least one 3DO game (Lemmings).
Many Sega Saturn CD-ROM games use this file format to store frames of a Cinepak-compressed video interleaved with uncompressed PCM audio. When this is the case, the files will typically have the CPK extension (which is why FILM files are usually known as CPK files).
