[Audio] RSE music in Fire Red?

Is there a simple way to just overwrite the music in FR with the music from Emerald? Are the voicegroups the same between the two roms?

There are a little differents, but the samples are the same, so if you want to insert something, you have to edit or create a voicegroup.

And then if you have wave memory square 1 2 and noise you must copy them.

As you can see here the instruments n°82 are the same.
You have to do that if you want import RSE track to Fire Red ^^
