You will notice most of the evf. mods are CS. Unless they have an installer, like Soldiers With Attitude - Desert Dash, you will notice most CSMs consist of a Hellendoorn_00x file. To install, simply copy (or extract, if the map file is in a .zip file) to the following directory, which is default: C:\Program Files\EA GAMES\Battlefield 1942 Secret Weapons of WWII Demo\Mods\XPack2\Archives\bf1942\Levels\.
To uninstall, simply delete the .rfa file you extracted/copied to your game's directory.
