Chex Quest

From PCGamingWiki, the wiki about fixing PC games
This page may require cleanup to meet basic quality standards. The specific problem is: Many of these should be marked as true instead of hackable because the rerelease uses ZDoom. You can help by modifying the article. The discussion page may contain useful suggestions.

Essential improvements[edit]

Source ports[edit]

Since the release of the engine's source code, various source ports have been released. See the link above for details and recommendations.

Chex Quest 3 uses ZDoom-specific features, and as such requires a ZDoom-based source port.

Widescreen Status Bar[edit]

Designed for compatible source ports that support widescreen resolutions. In addition to removing the brick patterns that appear on the side of the bar when upscaling it, it also helps prevent graphical glitches that sometimes occurs from the upscaling process. Some source ports may require adjusting the status bar upscaling size manually in their respective options menu to retain the intended aspect-ratio.
