I've been making low poly models but I'd like them to have the "pixelated" look that models have in some (mainly)older games. This especially includes PS1 games and 3D DS games. I'm not talking about the textures, but the way the overall thing is pixelated/no smooth edges. It seems to be the way the overall graphics were rendered. It's often more apparent when things are moving, but you can still see it in pictures too. Here's a few examples:
I don't know how to best get this look but I'd really love to know, it'd help me a lot.
