v1.13 has been out for a long time... why aren't you using that? And what do you mean by "clear"? You mean in a way that is only possible by enhancing? In that case, you will have to deal with ePSXe instead. And even that won't really make it clearer (you can't do much when you take an image and enlarge it to 4x its size).
To actually make it *clearer*, you'd have to raise the resolution of the games themselves. This would involve finding "hi-res mods" for the games you play.
