Playing Unreal Tournament 3 PC 4-Player Splitscreen Deathmatch with 4 Wiimotes

Halo 3 splitscreen deathmatch made me envy Xbox 360 owners. But not anymore. Thanks to some software (the same bunch), a freshly released hack, and almost two weeks of searching (I even tried to create dlls with VC++!) I finally got this to work. That is, in case you skipped the title, using 4 wiimotes to play UT3 on the PC.

Before, the only way you could pull this off was with 4 Xbox 360 controllers. Thanks to Racer S (http://tocaedit.com) and his freshly released controller emulator, my Glovepie-PPjoy-JoyID-powered wiimotes can now play the part.

And for the last time, my friends are not hiding somewhere with an Xbox 360. Or are they . . .

Coming Soon: a short guide on how to do this

EDIT: As promised, here’s how I did it:

Step 1:

Download this.

Step 2:

Install Glovepie and PPjoy. With Glovepie and PPJoy installed, you can connect your Wiimotes to your PC via a bluetooth dongle and use it as a virtual joystick. For the details, check out Wiili.org.

Step 3:

Setup the following PPJoy mapping for controllers 1 – 4:

• 6 Axes 16 Buttons 1 POV Hat
• Axes
  • 1 – X Axis – Analog 0
  • 2 – Y Axis – Analog 1
  • 3 – Z Axis – Analog 2
  • 4 – X Rotation – Analog 3
  • 5 – Slider – Analog 4
  • 6 – Throttle – Analog 5
• Buttons
  • Button 1-16 — Digital 4-19
• Directional POV
  • NEWS – Digital 0-3

Step 4:

Go to C:\Users\[user name]\Documents\My Games\Unreal Tournament 3\UTGame\Config folder. Replace UTInput.ini with the one found in the archive you downloaded. Here are the lines for the button mapping:

Bindings=(Name="XboxTypeS_A",Command="GBA_Duck")
;Bindings=(Name="XboxTypeS_Start",Command="GBA_ShowMenu")
Bindings=(Name="XboxTypeS_LeftX",Command="GBA_StrafeLeft_Gamepad")
Bindings=(Name="XboxTypeS_LeftY",Command="GBA_MoveForward_Gamepad")
Bindings=(Name="XboxTypeS_RightX",Command="GBA_TurnLeft_Gamepad")
Bindings=(Name="XboxTypeS_RightY",Command="GBA_Look_Gamepad")
Bindings=(Name="XboxTypeS_DPad_Right",Command="GBA_NextWeapon")
Bindings=(Name="XboxTypeS_B",Command="GBA_Fire")
Bindings=(Name="XboxTypeS_DPad_Left",Command="GBA_PrevWeapon")
Bindings=(Name="XboxTypeS_Y",Command="GBA_AltFire")
Bindings=(Name="XboxTypeS_LeftShoulder",Command="GBA_WeaponPicker")
Bindings=(Name="XboxTypeS_X",Command="GBA_Jump_Gamepad")
Bindings=(Name="XboxTypeS_DPad_Up",Command="GBA_ToggleTranslocator")
Bindings=(Name="XboxTypeS_RightShoulder",Command="GBA_ShowMap")
Bindings=(Name="XboxTypeS_DPad_Down",Command="use")
Bindings=(Name="XboxTypeS_Back",Command="GBA_ShowScores")
Bindings=(Name="XboxTypeS_LeftThumbstick",Command="GBA_Taunt2")
Bindings=(Name="XboxTypeS_RightTrigger",Command="GBA_FeignDeath")
Bindings=(Name="XboxTypeS_LeftTrigger",Command="GBA_ShowCommandMenu")
Bindings=(Name="XboxTypeS_Start",Command="GBA_Taunt1")

And here are the lines you’ll need to adjust for sensitivity:

Bindings=(Name="GBA_TurnLeft_Gamepad",Command="Axis aTurn Speed=2.0 DeadZone=0",Control=False,Shift=False,Alt=False)
Bindings=(Name="GBA_Look_Gamepad",Command="Axis aLookup Speed=1.5 DeadZone=0",Control=False,Shift=False,Alt=False)

If I remember right the aTurn Speed used to be 1.0, and the aLoookup Speed .65, with both DeadZones at 0.3. Anyway, if the settings I used don’t suit you, just adjust these values.

Step 5:

Go to your UT3 installation directory (where the .exe is). Copy xbox360cemu.ini and xinput1_3.dll from the archive. Thanks go to Racer_S of tocaedit.com for these files. The dll fools the game into thinking your virtual joysticks are Xinput controllers, the only ones UT3 were made to work with. I modified the ini file to work with four wiimotes. Here are the lines you might want to tinker with if you want to change the button mappings:

A=2                #button id; 0 to disable
B=3                #button id; 0 to disable
X=1                #button id; 0 to disable
Y=4                #button id; 0 to disable
Left Shoulder=5            #button id; 0 to disable
Right Shoulder=6        #button id; 0 to disable
Back=9                #button id; 0 to disable
Start=10            #button id; 0 to disable
Left Thumb=11            #button id; 0 to disable
Right Thumb=12            #button id; 0 to disable
Left Trigger=7            #button id; precede with 'a' for an axis; eg; a-6; for a slider precede with 's' eg; s-1
Right Trigger=8            #button id; precede with 'a' for an axis; eg; a-6; for a slider precede with 's' eg; s-1

But do remember to also change the corresponding line in the Glovepie script (next step).

Step 6:

Run Unreal3 4 Wiimotes.PIE in Glovepie. Some things to consider about that script. The code used for each Wiimote is identical, except for the buttons of Wiimote 3. For some reason, Glovepie sometimes does not recognize the first button (mapped in PPJoy to Digital 4). But in this instance, it only happens for Wiimote 3, which is PPJoy Joystick 3. So to get around this glitch, I just added 1 to all the PPJoy integers in Wiimote 3’s code by one (PPJoy3.Digital4 becomes PPJOy3.Digital5, PPJoy3.Digital 5 becomes PPJoy3.Digital6, and so on). This glitch might not occur in your setup. So if Wiimote 3 behaves differently, this is probably the reason.

I would post the script here, but because of the problems I encountered in the Left 4 Dead hack caused by the encoding of quotation marks, I chose to just give the exact file I’m using.

Step 7:

Make sure your wiimotes have controller IDs 1, 2, 3, and 4. To do this, use JoyID.

Step 8:

Connect your wiimotes to your PC and run the Glovepie Script above. The LEDs on the wiimotes will tell you which wiimote is player 1, 2, 3, and 4.

Step 9:

Turn on your Wii. This is just so the sensor bar’s IR LEDs work. Alternatively, you can use two tealight candles, make your own sensor bar, or use Nyko’s Wireless Sensor Bar.

Step 10 (Optional):

Go to \Users\[Username]\Documents\My Games\Unreal Tournament 3\UTGame\Config . Open UTGame.ini and go to the following line:

StringData=(Tag=”Splitscreen”,DefaultValueIndex=0)

Changing zero to 1 will make it so that splitscreen mode is on by default. This is annoying when you want to play alone. If you want to add each player manually…

Step 11

Hit Tab and type debugcreateplayer 1 to add the second player. Type debugcreateplayer 2 and debugcreateplayer 3 to add players 3 and 4.

Step 12

Reconnect your nunchuks. Initially they’re not detected.

Step 13

Enjoy! Remember to shake your wiimote (taunt 1) or nunchuk (taunt 2) every time you frag someone.
