Description
SPC is an audio file format designed for playback of native audio from the Super Famicom / Super Nintendo Entertainment System.
Information
The format generally consists of four main sections - a file header; a section containing SPC700 register data; an ID666 tag in either text or binary format, containing metadata about the file; and a final section containing RAM and DSP register data. In addition, there may be a fifth section containing Extended ID666 tag data.
There is also a packed / grouped format for SPC files, where groups of files are packed as a solid archive using RAR. This commonly uses the extension .rsn (RAR Super Nintendo)
