Ar Tonelico Qoga : Knell of Ar Ciel [BLES01102]

The "invalid mem access location" error which seems to be persistent during first item synthesis can be avoided by going into Interpreter (fast) mode. Afterwards, save the game and then we can resume using recompiler as usual.
My only question is, since the game requires motion detection from SixAxis, is there any possibility of implementing motion input without plugging a dualshock 3 or 4? Or perhaps a single button hack for this game?
The FPS is already quite good (30 FPS) and the only downside is being this motion detection requirement.
