I have just started delving into the world of FE ROM hacking and have a couple very basic questions that I cannot seem to find simple answers to in the large amount of information that is out there:
1) What commands do you need to use to simply write over data from a specific hex offset in an ASM build file? For example, Venno implemented a drop item flag shortcut for FE7 and his instructions to enable it are to paste-write "201C4130007840210840000000000000" at offset "0x17826." It would be nice to just do this in the ROM build file so that I don't have to keep using the hex editor every time I build the ROM again.
2) I'd like to add additional items to some shops that are already in the game. However, it appears that NMM only allows you to replace items and not add additional ones (unless I am missing something). How would I go about inserting additional items in existing shops?
Thank you for the assistance!
