My second Final Fantasy game I played and beaten, which back then I thought it was the second game as it were known as "Final Fantasy II" without knowing it were actually Final Fantasy IV. Even though I adore the 3D remakes (and the Game Boy Advance version) of this game, I love hearing Kingdom of Baron theme done in Final Fantasy VI style. Well done!
My first game in the series was FF12, then 13, then went back to the first game and started working my way up. When I got to this game the Red Wings and the Baron Castle theme made me forget this was a SNES game from the 1990s. Sure for FF1 to FF3, I had moments where I was like "huh, these games are old" , but FF4 is where the timelessness of this series began to show its true form
The good news is all or almost all of the original samples have been identified, so it essentially is the correct sound font, however some of the instrumentation here is uncompressed and others of it appears to have been compressed on purpose. It's not a bad choice I think. Some of the original samples just sound uncomfortably different when uncompressed compared to how it sounded in game, it was 1991 after all.
