@legolas119: The shader is actually in the CG shaders “CGP folder” called crt-royale-kurozumi.cgp. The regular crt-royale is just default settings. As far as the cropping, if you are talking about black space around the image, that’s what you want the original aspect ratio of the game and interger scaling ON for the scanline shaders to pervent uneven scanlines.
@jnsl: It’s a limitation or optical illusion of shaders or flatscreen monitors, or at least this shader. It will do it on vertical games that scroll vertically too, so ideally for vertical games you want to switch to a different shader that flips scanlines vertically. Actraiser 2 isn’t a vertical game, though… so you just have to deal with it unless other scanline shaders don’t do that? Experiment.
