I tried Amagami on this with the partial patch, and it was a mess :/ some texts were missing, the textbox weren't there, the intro blinked...etc. I only have Persona 3 (english) now and it works for me... (iTouch 4G, iOS 6.1). I tried Da Capo III, Oreimo and VNs like that, but it looks like that PPSSPP doesn't really like japanese games :/
