Isn't that what rom hacking is all about :P ?
Rom hacking is not mapping, not inserting tiles with a game-specific tile inserter, not adding more events to a map with A-map either by using some editor's command for "add new event here".
If you're not interested in what you're calling "hacking", why not learn how to do the stuff in a proper way then? You might have seen my earlier modifications on pokemon crystal which I made with zero-knowledge on hacking so far. Yet little by little, I started studying rom hacking in general, how bytes work, what bits are, what is "ram", how Gameboy processor handles data, ..., and I'm still on that path learning more and more all the time.
I for myself have quite a lot of free time to spend on rom hacking although I do have plenty of other interests as well. And even of this rom hacking part, let's say, 70% of it is really working on Dark Future. The remaining 30% goes for advising others, learning by doing so, asking questions, studying more etc.
Not sure why I really wanted to say all this but related to what I pointed out earlier, rom hacking is a lot more fun when you actually have to use your brain to do something. I also used to like doing stuff your way but it's really not that fun without having sort of a problem solving behind it.
