Well to tell you the truth , I didnt play ace attorney or dangan ronpa but i did watch a bit of their gameplay or hear their mentions.
and well it took me wrong guesses but at least i reached the true ending without seeing other endings, though I needed a walkthrough.
There are some complaints in the game like adding AI images in the beginning intro, have a stock RPGM/BAKIN character as the ceo rather than your drawing, when i press a save relating to a courtroom hearing , i didnt see it.
The neutral however is skipper who is drawn as a funny unknown.
Perhaps if there is a remake of the game perhaps in a different engine like a RPGM perhaps you can draw the backgrounds and figures.
