Retroarch 1.36+ PS3 - Changing shaders / video mode?

Hi folks,

I’ve been overjoyed to discover just how excellent 1.36+ already is, however I’m at a loss as to how to make my games look sharp. For example, Space Invaders on the Stella Core looks fuzzy, and I’d like it to look sharp. I tried setting the scaling to Integer, which didn’t appear to do much except make the image slightly smaller on my HDTV. I can’t seem to locate a shader menu in the options, I’m probably looking against my eyelids as usual.

So if anyone might have any advice for how I can change the screen display to show the pixels as sharp squares rather than blurry fuzzy dots, I’d really appreciate it!
