So I lurk here a lot and I didn't see alot of instructions for this so I figured, since i couldnt find anybody else that had done this I would post some quick instructions that I figured out on how to get this to work. I played through the first two missions of Thief Gold, the first level of Thief 2, and about an hour of system shock 2 with only small problems.

Things you'll need.

Vireio Perception Nightly v2.06
Oculus Rift (dk1 or dk2[Extended Mode])
Thief Gold/2/System shock 2 patched up DX9 Patch

Okay, so it's actually pretty easy.

Download Vireio Perception (referenced as VP in the rest of this doc)
(http://www.mtbs3d.com/index.php?option=com_jdownloads&Itemid=439&view=viewdownload&catid=20&cid=49)

Download Oculus SDK 0.4.3 beta
[Make an oculus vr account and download it]
If you are using a DK2, you MUST put it into extended mode, which you can access using the rift's configuration panel. EDIT: Also disable Oculus Rift DK1 Compatibility.

Patch up your copy of Thief/SS2

Extract your copy of VP to some place convenient.
Go into your VP/Bin folder and copy these files:
d3d9.dll
hijackdll.dll
libfreespace.dll
vrboost.dll
into your Thief/ss2 directory.

Run the perception executable from the VP/bin directory. This will actually turn on the VP drivers and get this whole shindig running. Leave it running in the background.

Go into your Thief/SS2 directory, open up cam_ext.cfg file with notepad, and edit the FOV to 110 (100 for DK2). Save it. (I might have this wrong, but it seemed to work for me, so please inform me if there is a better way of adjusting the FOV)

Now run Thief or SS2, it should load up on the rift, with some green text on the screen. Most of it is inconsequential for what you're doing, but a few tips.

MANDATORY!!
Go into the BRASSA MENU (CTRL-Q in Game) and scroll down to Force emulate mouse, and turn it to TRUE.

Less mandatory
Most everything is fine in the rift, Rolling your head (least on a dk2) has so far not worked for me, but everything else seems fine. So don't tilt you're head left and right. I have tried adjusting the roll settings in the BRASSA Menu and it just doesnt work, if you can get it working please let me know, and I'll update this.

If the perspective seems off, hit CTRL-Q, this will load up the BRASSA MENU. Go down using the arrow keys, to other options, and adjust distortion using the arrow keys and enter

Go into Other options and also scroll all the way down and bind a convenient button to disconnected screen. This will "push" the game window farther away from you while in VR and allow you to look at menu's in the screen, things in the corner (like weapons/items in thief) and allow you to access other things easier without going crosseyed. Kind of like having a virtual monitor inside of the game. This is an absolute must if you plan on playing system shock 2 without giving yourself a headache.

It's pretty easy to play and it makes thief look amazing, so try it out guys, and have fun.

Might want to add a little more explanation as to what this is all about because I've got no idea what we're talking about here.

I'm having trouble getting this to work with Thief Gold. It keeps launching on my monitor instead of in the Rift. I see the two distorted views and head tracking works. I have an extension installed that's supposed to launch something on adapter 1 instead, but that doesn't help. When I made my Rift the Primary monitor and then launched Thief Gold, it didn't display anywhere (though it was running).

I'm having other minor issues that don't matter until I get the big one fixed, but:

Sometimes when I launch, the mouse cursor wants to stay in the upper left no matter how I tilt the Rift or move the mouse. Other times, it's fine and can be controlled with either the Rift or the mouse. I don't know what causes the difference.

Edit: Oh hey, I guess I only have the issue with the mouse when I use the extension to launch on adapter 1. Edit again: Never mind, it's not consistent.

Also, Ctrl-Q isn't doing anything.

Edit for an update:
I was able to get the game on the Rift by enabling Windowed mode in cam_ext.cfg and making the Rift the primary monitor. Turning my head makes things turn way faster in the game. Is that what the Brassa menu option is supposed to fix? I see a flickering yellow rectangle across the screen when I try to open the Brassa menu. I assume it's for selecting things in the menu or something, but it's all that I see.
The FOV is kind of strange, too. I think the game is still showing in widescreen mode, so it's letter-boxed in my view.

It's a setting in the oculus configuration manager under rift display mode. Make sure it is off. If you don't see the option, you need to update your rift.
