What is an RSN file?

RSN files mostly belong to Snes9x. An .RSN file is a music archive primarily associated with the SNES (Super Nintendo Entertainment System) and contains game music data. It typically uses the RAR compression format internally, meaning the actual music data is compressed using the RAR algorithm. These files are mainly used with SNES emulation software like Snes9x, allowing users to listen to the game's soundtrack. While the .RSN extension itself doesn't dictate the internal format, its strong association with SNES music and the common use of RAR compression makes it a recognizable format within the emulation community.
