If anyone is still having issues with this, like already mentioned I recommend bilinear filtering and setting the aspect ratio and resolution in the retroarch.cfg file. I am still tinkering with the PSX for me shaders are all rubbish, would love high res textures but doubt the pi can handle it
I play FF VII and someone one redid all the textures and models in the PC version and really does make the PSX version look like a Vic20 edition :D
