I have been working on this for a good 2 month now and I just wanted to reveal to the world what I was working on. It's a fully working (well, supposed to) editor for Phoenix Wright games. Right now, it is very basic (you can only change text and events. The pause, animation, and sound editing currently just break the game) and only supports one game (Phoenix Wright: Ace Attorney). It also can't properly parse text (weird script events and you can't edit the colors... yet!).
I will release this amazing piece of celestial ambrosia this year.
Stay tuned!
