If you have a set that is made in 128, and want it to be higher res...
like 512 there ain't no other way than to re-make the set in 512.
You can't scale without quality decrease, pixels don't work that way, vector however does.
Ok, so I have to pay an artist dude to do that cuz I'm not good arts myself. What would be normal price to pay for 128s to 512s quality upscale?
