I'm sorry about double topic, but I really need to explain what you found. First, it seems that what you searched (I know, because I searched it too) was getting you into ROM downloads, not into what I am trying. What I'm trying is to create some new stages in order to learn about this type of programming. Also, if you are so downright (I'm not English, sorry if it is the wrong word) about the copyright of a game, could you please find me a game I can legally edit?
