I managed to extract the files from Fate - Samurai Remnant (A Koei Tecmo game), but I couldn't extract the audio files in .srsa.

Persona5 quick bms script didn't work at all, but the engine and file format is almost the same. The folder where the audio files are stored is named root. I will give a sample of the files, including .rdb and .rdx files that I found.
