Power Stone 2 help

[RRMC]

Since the Echelon way of making my games selfboot doesn't work (can't open new session) , I use Bin2Boot. I have decided to put custom music in Power Stone 2. My backup was made selfboot with Bin2Boot, and my non-selfboot copy was destroyed.(not the original!) I am thinking that the easiest way to do this is to burn the plain files with my custom ADX files, but it doesn't work that way because of the Bin2boot process. I need to know how to reverse it. Now that I know how, I am having trouble. Being new at this, I don't know what CD001 is. Is it in the 1ST_READ.BIN? Or the IP.BIN? Or is it in any other files? I have tried searching for it file by file, but I can't find it. What is it?
