Thats right, you can play SMBX with 1 (Or two) Wii remotes. And I will show you how!
Step 1: Bluetooth
Using your bluetooth PC or.. whatever computer/laptop, open up bluetooth, Add a device, and when it's searching get out your Wiimote and Press 1 + 2 at the same time. You shouldn't have to hold it down, as it will flash by it own after pressing it once! After One is synced, you can do it again with a different one or just use one for singleplayer. If it asks you to input a passcode, leave it blank and click 'next.'
Step 2: GlovePie
Download GlovePie Here:
http://glovepie.org/lpghjkwer.php (Or at any other site) and extract all. Then find GlovePie.Exe and run it. At the top click Untitled (The first one) and paste this in:
Key.Escape = Wiimote1.Home
Key.W = Wiimote1.Left
Key.A = Wiimote1.Up
Key.D = Wiimote1.Down
Key.S = Wiimote1.Right
Key.X = Wiimote1.One
Key.Enter = Wiimote1.Two
Key.F = Wiimote1.B
Key.G = Wiimote1.Shake
Key.P = Wiimote1.A
Key.Escape = Wiimote2.Home
Key.K = Wiimote2.Right
Key.I = Wiimote2.Left
Key.J = Wiimote2.Up
Key.L = Wiimote2.Down
Key.N = Wiimote2.One
Key.Shift = Wiimote2.Two
Key.M = Wiimote2.B
Key.Z = Wiimote2.Shake
Key.C = Wiimote2.A
Then click Run (Again, at the top) and the Wiimote should stop blinking.
Then click Stop (Where Run was)
EDIT: Fixed Drop item controls, now both players can drop their own items.
Step 3: SMBX
Fire up SMBX, go to player one controls and enter this in:
Input-Keyboard
Up-S
Down-W
Left-A
Right-D
Run-X
AltRun-F
Jump-Return (Press Enter, NOT on Numpad)
AltJump-G
Drop Item-P
Pause-Escape
Then for Player 2:
Input-Keyboard
Up-K
Down-I
Left-J
Right-L
Run-N
AltRun-M
Jump-Shift (Left or right)
AltJump-Z
Drop Item-C
Pause-Escape
Then go back to GlovePie and click Run.
Hold the Remote sideways and heres a rundown of the Wiimote controls:
Kind of like NSMB Wii
Up-Up
Down-Down
Left-Left
Right-Right
One-Run
Two-Jump
A-Drop Item
Shake-AltJump/SpinJump <--- (My Favorite)
B-AltRun
Home-Pause
Step 4:Fun
Open up any episode/Battle mode and play! Have fun!
This really comes in handy for 2 player or battle mode if you don't have a controler.
I want to note I have not tested 2 player mode or battle mode or 2 Wiimotes. I will soon. EDIT: I have tested both, they work.
