Grafx 2 is "the ultimate" 256-color pixel art app

Designed to look like something running on the Commodore Amiga but with all the modern conveniences, Grafx 2 is pitched as "The ultimate 256-color painting program."

GrafX2 has a long history, with the first versions being published in 1996. The development by the original team (Sunset Design) continued until late 1999, when they stopped working on it because no one had interest in running a DOS drawing tool by then. Fortunately, they published the sources so that their work would not be lost.In 2007, PulkoMandy recovered these sources and ported them to modern operating system. This was the rebirth of GrafX2, which then saw many improvements and finetuning, making it the great tool you know and use today.

Neat touches include extreme custom resolutions (including nonsquare pixels), powerful pallette manipulation (including color cycling) and a prominently pixelated King Tut, as is mandatory for all pixel-art related Amiga shenanigans.
