I am currently having my first try at rom hacking a NES game and have an issue trying to modify text in a specific menu. I sincerely hope this isn't a really stupid question.
I have modified the text in the hex editor for the parts required but this particular menu has the text over two 8*8 tiles, re-using these tiles on different parts of the screen (as in top half of A and bottom half of A). As I understand it they obviously aren't a single address as they are two tiles that are re-using common tiles to display text? Does the hex code of the rom store what tile is displayed at x/y location on backgrounds? I have played around with a debugger trying to figure that out but have gotten nowhere.
If anyone could point me in the right direction for some info or some other resources i can look into how I go about this it would be greatly appreciated.
