And to point out how badly used the soundfont is... consider the gym leader theme, specifically the part at 41secs
https://youtu.be/1pBl5sWchJY?t=38In the original, Junichi Masuda does its classic move: Toning down the melody to avoid giving you headache if the battle lasts for 5+ minutes and also rising the tension in a menacing way. He does it all the time, **without breaking the rhythm of the battle** because he knows how to use the background notes to keep the fire burning
https://youtu.be/ufYIjzq_QwA?t=39The remake though?
The guy in charge wasn't smart or skilled enough to understand how to stop the melody without stopping the tension, so you have 5 seconds where the rhythm is totally stopped, as if someone paused the battle.
Notice how he tries to use drums to help him during those 5 seconds but it does nothing
Again it's not bad, but GSC vs HGSS is like that all the time in all areas, not just the music. It's the small details that makes people wanting to go back to it again and again even if the remakes are more "modern"
