I've tried to add some Unova remixes in the Unova ID folder but after adding it into the game, everything went silent. Only the tracks I didn't change could play. The customised ones, just nothing plays.
This is what's inside my mod folder.
This is inside the mods folder.
And this is inside the Unova folder, numbered 2.
I've added quite a lot of songs lol, but none of them seems to work. I really need help.
