What are some good tools for doing 1990s pixel art? Specifically sprites, but maybe some larger backgrounds. I see someone's done a JS version of DeluxePaint! Any others people really like?

Slightly heretically, I'd love one that handled alpha channels well.

Recs so far:

Aseprite
Pro Motion NG
grafx2
piskel
pyxel edit
Pixelorama
Cosmigo
Libresprite

My brain is very small, so starting with the #1 most common which is Aseprite.

@TomF I'd recommend Pixelorama over Aseprite these days, it's mostly a clone of modern aseprite but merging in a bunch of QOL changes (and obviously using godot for UI so it's a bit more modern) where Ase stagnated quite a bit after they split from the GPL2 version and locked it down to a commercial license, it doesn't even do stuff like onion skinning very well.

Also don't sleep on GIMP, it's an incredibly powerful pixel editor
