Its integration with verge is simple. A call to PlayMusic("module.it") will attempt to look for the files `module.it_` and `library` in the same directory. If it finds them, it will load them as repacked modules. If not, it will attempt to load `module.it` directly before giving up.
It is thought that this interacts flawlessly with the pakfile system. Please contact zeromus if you encounter any difficulties.
As an added bonus, my_sfx.wav_ can be loaded the same way, resulting in around a 40-50% decrease in sfx size.
