FF4kster, the all-in-one editor for Final Fantasy 4 has been updated yet again. This time, along with the usual array of bug fixes and minor improvements, there is an autobattle editor that allows you to change which battles are scripted as well as the scripts themselves. In addition, the program now contains a rudimentary map editor which allows you to edit the inner maps. The tile graphics have been blatantly ripped from FF4Tools, but if all goes well they will soon (hopefully by the next release) be dynamically read from the loaded ROM instead.
Several additional battle commands now have parameters that can be edited as well, including Steal, Boast, Cry, and even Fight!
