I was wondering how I could learn how to start Rom hacking in Java. I've been programming with Java for about 6 years now, but have no experience with Rom hacking.
For the sake of a simple example I want to load a unchanged us rom of Super Mario Bros. and change where it says "Mario" in the top left of the hud (I think it was?) and replace that with "User1" or something.
I know this would be done by going to the memory address that has "mario" in it and changing it, but how do I go to a memory address in a file? The only thing I got is a offset, and length variable if this is done the way I'm thinking.
