Looking for help on where to find and edit certain information on the ROM

[jacobman]

Hi, thank you in advance for any attempt to help me.

There are two hacks that I would like to do on Pokemon Diamond. I would like to edit the egg move list of pokemon species, and I also want to edit the script that prevents HM's from being used without certain badges. I'm assuming it's a script.

I'm hoping someone knows the format, narc file, and/or offsets where this information can be found, but any help would be appreciated.

UPDATE: I found where the egg moves are, but I still don't know what I would have to change to allow HM's to be used without badges.
