As far as i know all eqmu servers require the original game files to be in your computer. That alows you to play on all the original game zones with no bonus races or zones, ie kunark or van shir, some of the older expansions, up to kunark are stored whether you have them or not, thanks to some old patches. This allows you to go to kunark without expansion, but it limits all models and textures to textures that you already have on your computer, like all the monsters apear as humans with funky names. You can also install the expansions on your computer, without registering them officially and you can still play eqmu just the same.
