Post-process image camera shaders OpenGL 3 (WiiU)

Hi!

We are developing a 2D game for both PC and Wii U. On the Nintendo's console version we've successfully updated all of our shaders so far to OpenGL, but when we run our game on it, all the Unity Pro camera image effects are gone. The cmd console log raises several compatibility errors for all those shaders, and refer them at "Hidden/xxx" (e.g. "Unsupported: Hidden/DoF/Bokeh34").

Is there something we can set up to make them work? Can we access those shaders' code somehow to modify them and adapt them to WiiU's environment?

Thanks in advance!
