Super MegaZeux

SMZX Mode is the name for an alternative graphics mode accessible through MegaZeux. It was first introduced by MadBrain in the form of a modified MZX 2.51s3.2 executable. This original version was referred to as Super MegaZeux 100 Alpha (smzx100a). In the most recent versions of MegaZeux, SMZX Mode can be accessed by setting the SMZX_MODE counter to 1, 2, or 3.

How It Works

SMZX Mode halves the vertical screen resolution in favor of adding two colors per character, effectively making a color palette of 256 unique colors.

Mode 1, the original mode, simply blended every two horizontal pixels together. The usefulness of this was at first only shown in making smooth gradient fills and grayscale images.
