### Important notice to users of
SH3 Commander ###
Jonesoft has made available updated files to ensure compatibility between GWX and
SH3 Commander,
a Jonesoft freeware product that allows players to edit many of the parameters and settings for a player’s
career in Silent Hunter III. Take the following steps to configure SH3 Commander for GWX:
• Ensure you are running SH3 Commander R2.6 or greater, as releases prior to R2.6 are not
supported.
• Download http://www.users.on.net/~jscones/GWX/GWXCfg4SH3Cmdr.zip and extract the
contents into your SH3 Commander\Cfg folder. Refer to the readme.txt in the zip file for more
detailed information.
The GWX team suggests you set the following SH3 Commander options to get the most enjoyment
while running with GWX:
• Select “Use historic U-boat availability dates” when playing a career in the 30th/33rd flotilla
• Select “Set number of days spent in base” to 55 when playing a career in the Far East
• Do not use the “Grey Wolves 24 hour” fatigue model
• Do not use the “Combined Ship Pack” add-on
