Deluxe Paint II Enhanced V3.0 - Image Editor (PC/MS DOS)

Deluxe Paint was THE pixel graphics tool on the AMIGA 500. The PC version came a bit later and development was not continued on the PC like on the Amiga, where DP made it to version 4 before it was stopped there as well. It was still ahead of its time when it came out.

This version of Deluxe Paint is the "enhanced version" which supports "Super VGA" (256 colors BEYOND 320x200) to some degree (not really, but they made an effort). It should still run on most people's Windows XP PC.
