Well, I did the first thing you said, searched for anything already made... for the specific game I was looking for, there wasn't anything made...
I'll have to look into it. Maybe I should start with NES games first, though? I am pretty new at this, and I have a habit of etting ahead of myself (its too complicated, and I only spend a day or two trying to figure stuff out before I get tired of it.)
