I Unchecked it and It made it Worst. You can see the Pixils but now without the Blur. ... and that's how it's supposed to look like without Bilinear Interpolation. We're talking about software renderring here, not Direct3D or an OpenGL renderers like the ones ePSXe (and other plugin-based PSX emulators) uses. So there is no hardware acceleration nor anti-aliasing of any kind, aside from the few DirectX stuff used fro bilinear interpolation, for example. pSX tries to emulate the Playstation as accurately as possible, starting from the graphics. Graphics will never look the same on a monitor than on a TV screen either. Software rendering will look cruder, especially when pSX most likely uses a resolution native to the original PSX (from 256x224 to 640x480 depending on the game; lower resolutions are also most likely upscaled by your graphics card if you monitor does not support resolutions Also the problem you are having with ePSXe have to do with your graphics hardware not being up to par with what is generally needed to get fully supported graphics emulation, and while it might work seemingly flawlessly until you get to a boss fight, something obviously craps out when the emulator tries to do something graphics-wise that your graphics hardware cannot handle. many emulated PSX games exhibit such errors because the PSX graphics routines aren't the the most simplistic ones. Updating your graphics card drivers probably wouldn't hurt either.
