A question of "semi-3D" racing sprites

[puggsoy]

Usually in these kind of "semi-3D" racing games, the sprites are scaled by the game's code, and don't actually have the sprites at all those different sizes. You should only rip the sprite at it's normal size, although if you're hard-ripping then it could be difficult to find it like that.

As Deathbringer said though, if you could tell us which game that might help.
