Well I put this in my project and there's no more anti-aliasing in windowed or full screen mode, but it's also not pixel perfect for me. There's quite a few pixels that aren't square. I have the plugin enabled and have tried moving it around the plugin list, and nothing is working. The only other thing is that the plugin menu says it "may not support" MZ. It seems to be working fine for everybody else so I'm wondering if I'm doing something wrong?
Edit: It was a screen size/resolution problem. It's only truly pixel perfect if the game's screen size can scale properly.
