Game Description:
The Immortal is an action adventure game for the Nintendo Entertainment System.
Hack Description:
The Immortal on the NES has video sync issues with some televisions, causing a wobbly picture, or complete loss of signal.

This is because the NES has one colour in its palette that represents an extra-deep black that televisions may confuse for horizontal or vertical sync signals. Most games avoid this, but The Immortal used it continually.

This patch replaces that invalid black with the standard black colour instead.
