The Linux versions (X2 and X3:R) and Mac versions (X2, X3:R and X3:TC) of the X-Games weren't developed by Egosoft but by external programming partners, which are Linux Game Publishing for the Linux versions and Virtual Programming Ltd. for the Mac versions. You can get patches as well as technical support on the sites of these companies. For Linux Game Publishing this is http://www.linuxgamepublishing.com and for Virtual Programming http://www.vpltd.com.
