Double the size of a sprite without quality loss.

[Koetje]

Hi guys!

For an assignment at school, I have to code an existing arcade game in c++. I have choosen Contra to remake, so I looked out for the required sprites. I have found the orignal ones, but I'm working at a resolution of 512x480 (double of the nes resolution).

This means that I have to double the size of the sprites. But when I do this, the sprites start to get blurry and ugly.

Is their someone who can do it correctly (or make the sprites at the right size?).

The sprites I currently have are attached to this post.


Thanks guys!
