Source port parameters

Source ports support various extra command line parameters not found in vanilla Doom. Below is a list of the most commonly used ones.

-complevel &lt;compatibility level&gt;

 * PrBoom


 * Toggles various bug fixes and enhanced features for maximum compatibility with other (related) source ports. A compatibility level of -1 means that all enhanced features and bug fixes are available, while 0 through 4 correspond to vanilla Doom, 5 corresponds to DOSDoom, 6 corresponds to TASDOOM, 7 through 9 correspond to Boom, 10 corresponds to LxDoom, 11 corresponds to MBF, and 12 through 17 emulate earlier versions of PrBoom.
