The dcxsetup4j1.zip file you have requested: Modifications / Desert Combat Extended / DC_Extended - 22.26mb is not available. Perhaps try browsing all files for the game Battlefield 1942 and upload any files you want to share or are missing. This is the only information we could locate:
The big story is that DC_Extended now works with DC 0.4J. Handweapons , vehicles etc. It also has conversions of all the new Desert Combat .4J maps. All "DC" maps now have "DCX" vehicles and are fully supported by DC_Extended. We've also added support for the DCTextures mod. Although DC_Extended has it's own theme and map based skin switching, many people requested that DC_Extended be compatible with DCTextures to avoid duplicating files in DC_Extended folders.
