[ROM Hack] How i insert this intro?

Sorry if my English is bad, I talk Spanish :D

Hey! What's up? I'm new to Pokecommunity And I have a little doubt. Does anyone here know how to insert this intro to FR from Windows? The repository comes with a tutorial, but it is for Linux :(

Here the link:

This is the wrong subforum, you should ask here instead: https://www.pokecommunity.com/forumdisplay.php?fn=decomp
