ff3se 2.12

I'm a bit confused with the hack. On the top of the "data info", it mentions the monster graphics being located at "E9A820" (which I assume is where the graphics are in ROTDS). I know I need to change that to F20000, which is where my monster graphics are located. However, when I look down at the code with asterisks next to it, the code mentions stuff in C1, not E9. Do I change C1 to F2? I'm not sure how this thing works exactly.

Also, the ASM hack code is different than the data info file, so I'm not sure how to modify these files in tandem (I thought they would be duplicates of each other, but they aren't). I just need a bit more guidance in regards to this. Thanks!
