When Rinnosuke finds Cirno standing over the remains of his broken camera, he decides he doesn't want to settle the matter with a Danmaku battle, as is traditional in Gensokyo. While reporting on the conflict, Aya remembers an article she wrote about how such things are settled in the human world, and convinces Eiki to set up a courtroom, with Aya herself acting as defence.
The end result- a Phoenix Wright clone with Touhou characters!
It's now been translated by N-Forza of the Shrinemaiden.org forums. There are actually two versions of the first game (and a sequel), and the patch is for Shin Gyakuten Touhou, the remake. It seems doujin makers are now so authentic in copying their source, they've even brought out an updated version almost straight away, just like Capcom!
