Unsupported (Multiplayer support)

From WSGFWiki

Definition

A game with "Unsupported" widescreen multiplayer support is a game where the method for making the singleplayer mode hor + does not work in multiplayer mode at all. The most common reason is that the singleplayer mode requires manual FOV adjustment, but the command to increase it is treated as a cheat code and is disabled in multiplayer mode.

This definition does not apply to games that lack singleplayer modes, or games where the singleplayer mode lacks a method for making it hor +.
