Ripping sprites from an N64 game.

First, make sure they aren't actually 3d models.

If they are actual sprites, you could find a better emulator or do it by hand.

They're not 3D models. And I'm not sure if it's the emulator. I mean, naturally for the sprites to be screencapped correctly, they'd have to be at the correct resolution, and I'm not sure what that is. Also, what do you mean by hand...?
