What is this page for?

Quake III Arena and other games based on its engine has a bug/feature that causes configuration files (aka "configs") of differends game modifications (aka "MODs") to be cross-contaminated with settings from other MODs.
This has nasty effects such as crashes with "recursive error after: MAX_CVARS" error and variables (aka "CVARs") that have no effect, confusing gamers who are trying to tweak their settings. This script is designed to compare current, "contaminated" config with a "native" config, i.e. one containing only mod-specific variables and weed out foreign CVARs, preserving the original values/settings from the contaminated config.

Navigate to your desired MOD folder (ex: baseq3, OSP, CPMA, InstaUnlagged, UFreeze, battle) and find "q3config.cfg" file, paste its contents into the LEFT panel.
Note: your custom scripts may be lost during cleanup.
RIGHT panel is for "native" config. To get a native config, connect to a server running a MOD who's config needs to be cleaned, type:
/cvar_restart
/reconnect
/writeconfig clean

Navigate to your MOD folder and find a newly created "clean.cfg" file, paste it's contents into the RIGHT panel.
