Can someone tell me how to add a bga to a song file been trying for a bit and can't figure it out

Sure.

In the song you are stepping, (should be along these lines... Assuming using SM5.)

Songs/My_Awesome_Pack/My_Song_1/<Files>

Inside the Files directories, you can add BGA's. Make a folder, name it something, and inside the folder, you will need a .lua file minimally. You can add images, sounds, etc as needed. When it comes to BGA's though, DO NOT use custom commands/update commands. Stepmania does not like that. (Unless you are using only one BGA...) Multiple BGA's will cause issues with updating commands. (They overlay each other and never end.)

Edit: To use it, simply press 'b' on the editor or add it manually in your step/chart.

Edit: If you are using 3.9, you will have to use/make .xml files instead. You can read more here: http://rhythmarcade.com/wiki/stepmania/ ... g/commands
