[RESOLVED] Shader especific for game!

There's any way to make retrobat (using retroarch) load a shader to a especific game??
So, I wanna load a especific shader for some 2D games.

Yes, all options can be set per game.

Long press South (B) button on the game (instead of short press that launches the game), go to advanced game configuration (the last option), and from there perform the desired settings for the game.

Thabks.
Gonna do it here!!!

EDIT: the only thing I can't do, is customize the filter parameters, but works fine.
