Trying to figure out how to add DC1 support to scm3Mus

[NepDisk]

I'm currently trying to figure out how to add support for DC1 (Di Gi Charat Communications 1) and I thought about editing the code for DC2, the issue I am having is trying to figure out the mcm_offset , song_hdr_table_offset and the song_base_offset.

In a hex editor I went to those hex values in the DC2 ROM and saw an MCM and a ";", I then checked the DC1 and saw that there were lots of MCM and ";" in the ROM for DC1. What should I look for so I can figure out the mcm_offset song_hdr_table_offset and the song_base_offset for other scm3lt games?

I am sorry if this isn't the best place to post this.
