SmashBrosLauncher XML Help? ocarina codes with Drakemaster's multiboot?

[Xarael]

I'm using the SmashBrosLauncher XML (with custom 1, 2, and 3 thing for different hack sets) and I want to use PW's Stage expansion codes (or other ocarina codes for that matter) but with the custom XML I don't know where to put the .gct file (RSBE01) and also the different hooks have me comepletely flustered: can anyone tell where to put the file and what hook to use? anyone? please?

I'm listening.

RSBE01 for hackset 1 goes in the custom1 folder,
and quite honestly, I have no clue what those hooks are.
I made that XML using bionicsonic's as a base.
I don't think the hooks even make a difference...

By the way, I just finished writing a program to build a code that goes
along with the stage expansion code. It is based on
phantomwing's tracklist modifier. What it does is allow
the stage expansion stages to play songs from stages other then battlefield!

It will be in my vault after Easter.
