Which file do I have to edit to change the name of the song that is displayed at the beginning of each round?

I seem to have trouble editing subroutines, for example Marios fireball, because BrawlBox keeps deleting every Subaction of stuff I edit, and SmashAttacks does not seem to be able to display Subroutines. Anyone got an altenative programm or Method I could use?

I made a Lucario which has different effects on his attacks for his first costume. After a lot of runs I noticed that it seems to freeze everytime I attack while turning, and I couldnt find anything in the turning section of the file. Any tips?

I'm trying to make different elemental versions of Lucario, but everytime I change anything in with SmashAttacks the Game freezes once I choose him in the character selection screen. Is there anything special I need to change/add before changing the flag of the subroutine?
