Wrong place sweetie. ^_^; *Movsie.*
ROM hacking, and games made by RPGmaker are different.
ROM hacking, you have everything there, you're just gotta make some custom modifcations.
RPGmaker, you have the engine, but you gotta make the map, story, events, coding, ect.
Trust me, I've been in both worlds. ~.^
But the one thing they both have in common, you gotta be creative. ^0^
