What are all of the game endings? (SPOILERS)

[Aus10]

I got through most of the game, but I borrowed it from a friend and had to give it back before finishing. I don't think I'll ever play it again, so I just wanted to know what all of the endings are. I was totally lightside, and I can guess its ending, but I have no clue for darkside.

Also, what do Revan's robes look like? Do they look like in all of the 'visions'?

In both games SPOILERS You find out, through a quick confrontation with Malak, that you are Darth Revan and the council had you brainwashed then tried to recruit you. If you're good, the game ends with you saving Bastila (who had been turned to the darkside) , Killing Malak, and becoming a full-fledged jedi knight. If you're evil, before confronting Malak, you can convince Bastila to remain evil and come fight for you. Jolee and Juhani (those arseholes) will say a general "It's either her, or us" speech, at which point you make use of their corpses as sponges to mop up all the blood shed while kicking their arses. On your way back the the Ebon hawk, Mission and Zaalbar refuse to help you, so you get to waste them too. Carth will run away, but he'd probably get eaten by some rancors anyway, so forget about him. You from that point go to the star forge to confront Malak and reclaim the title of Dark Lord. After killing Malak, Bastila uses her battle meditation to help the sith fleet crush the republic and everyone (except the good guys) lives hapily ever after

And as for Revan's robes: They do indeed look like those in the cutscenes, except you can't wear the hood or the mask (but you do look quite similar wearing a Sith Mask, Found in Master Uthar's chambers on Korriban )
