There's an emulator for SWG before the Combat Upgrade was pushed out, which completely redefined the way the game was played (and made it much worse in the opinion of the majority of players at the time). It's extremely buggy and a number of professions don't work correctly, but it's fun to play regardless. You can find out more about the emulator at the
SWGEmu Forums. For the most part, the setup is pretty easy. The Liberator server holds the stable code for players to actually play the game with, while the Test Center holds all of the new code that's being released, so it's a very different game there, and really made more for beta-testing and bug hunting.
It's ludicrously nostalgic to go back and play the game, though. SWG used to be an obsession of ours until they pushed out the Combat Upgrade, which just made everything feel too dumbed-down and WoW-ish at the time. Then they released the New Game Enhancements, which just made it all that much worse, and we left.
(The graphics are still sub-par, by the way, but the game itself is too much fun for us to care about that.
