I programmed a save editor for Animal Crossing: New Leaf and put way too many hours into it, and am currently in the process of rewriting it when I feel like it. So in the offtime, I want to work on other editors. The only real requirement is that the game is available in NA/EU already, and won't require me to update my firmware (I'm at 9.2). And of course, don't request something too extensive. For example, writing a town & acre editor for ACNL is extensive. Inventory and money modding aren't. I am willing to buy games that look interesting, in order to make a save editor. And it will be open source, written in Java. Not C# nor C++.
