[Audio] Sappy not opening rom

Hey eveeryone,
I want to replace some music tracks in fire red. I open up sappy and try to open my rom but, when I click on the rom it loads for a second and sappy just closes by itself. I'm confused and would like to get this resolved.

Sappy has had a notorious history of crashing Pokemon ROMs / not working with newer operating systems but thankfully there's an edited version that improves its compatibility. This tutorial shows you how to get the edited version as well as giving a brief overview of how to insert music.
