Naah, too much to do at the moment. Besides, I doubt anyone is going to be quite as interested in this as you are. But really, romhacking does not get any easier then this. You could probably make the edits in Notepad if you really wanted to, though that could get tricky.
Just open up the ROM in any hex editor (I like XVI32
). Scroll down until you see the text appear in the right-hand side of the window.
Type over the text with whatever you want. Ideally, your replacement text should be exactly the same length as the initial text.
If the new text is of a different length, then click on the left-hand side of the window in the cell immediately to the right of the one that is currently highlighted. Type in "04".
