I'm new to game development, and my skills with Photoshop are not that great.

I was planning to try to convert a old game to HD, but for this I need HD sprites. What is a good way to approach converting 8/16 bit sprites into something like HD? I mean something like this:

  • \$\begingroup\$ Thank you for the comments! I've tried Inkscape and it doesn't do that good of a job. I will probably need to redrawn the image like Draco18s said. I was thinking drawing them on paper and then vectorize with illustrator... \$\endgroup\$

you could try waifu 2X thing is youll have to make all the sprites look antialised first. find a way to size them up using the other methods people already mentioned, then re scale them down using Berlinier sampling, and then upload it to http://waifu2x.udp.jp/ and youll be happyenter image description here

legit what i got it to do, to the donkey Kong game over screen.
