In addition to the screen-filter plugins, you can download and apply a Shader plugin for the ePSXe, such as ePSXe SPU core 1.7.0 and Eternal SPU Plugin 1.41.
The best ePSXe full-screen filter settings can be obtained by using Pete's OpenGL2 PSX plugin. When used in conjunction with custom plugin shaders, the filter makes a picture with stronger colors and blends in some of the shades to hide the hexagonal 3-D model flaws that were common in classic PlayStation games. Screen-filter plugins improve the 3-D model textures of the game sprites and enable anti-aliasing, smoothing out the sharp corners of the polygons that are used to make the 3-D characters.
