Copying to your ROM a song available on the Forum

I got it!  Yay!  Thank you so much!  Just hearing the song feels really satisfying.  So apparently the 200 bytes DON'T carry over with pointer values?  I will admit the header is cumbersome to use, though I use it because the software I use asks for it. (I think, it's been a while).  Can you tell me a software where I can freely remove and put back headers?  I think my coding would be a lot easier without all this byte conversion.
