Yeah, I ended up figuring that out eventually. Good to have confirmation about it.
So the reason I was trying to edit the game was to put Rokko Chan into Rockman 7 FC! I'm done with all of the modifications, so here is the finished product. I'm rather happy with how most of it turned out, especially the Golden Beetle Adapter used to replace the Rush Adapter. If any of you are interested in using this, let me know what you think!

Primarily changing Dr. Wily to Dr. Mad from Rokko Chan. The biggest obstacle there is getting the sprites ripped from the game, as they seem impossible to find right now. I also might change the "Rock Man walking" animation from the end of the game, but I couldn't find a way to convert him to Rokko Chan in a way that looked good.
P.S. There are actually two palettes for Rokko Chan included. The default one uses the colors from the "Weapon Get" images of Rock Man for the weapon colors. Rokko Chan's forehead gem was also changed to a darker red and I gave her the chest gem from her official art, that isn't seen in the original sprites from her game. The original sheet uses the weapon colors directly from Rock Man's in-game sprites, which I didn't think matched Rokko Chan's design as well.
