It's pretty much exactly like any other image you've ever edited, just remember to save it in 256 colors.


Here's 2239 random enemy sprites, most of which came in a single pack - you might already have it, but I can't remember exactly where I got this so I'll just host it. There's stuff from Landstalker, FF6, and a bunch of other SNES/Genesis-era RPG sprites, as well as a few junk ones that came with the pack.
