Cleitan, of course the sticks work, all the buttons and triggers work. That's what the software that comes with the adapter is for. After you install it, go to Control Panel>Gamepads>Properties (I think), you can test the sticks and buttons from there. Make sure you press the Analog button on the controller, and that the LED is red.
Orion, sorry but your setup won't work, because of the way the different slashes are implemented in M&B. The camera directions are with respect to looking forward (to do a slash from right to left, you first look to the right of forward). With JoyToKey you can make the first attack, but there's no reference to what direction is "forward", so you must move the camera manually back, before making a different attack. I think it would require a key to re-center the camera behind your character (which would be handy anyway). But at present, although it can support some complicated functions, I don't think JoyToKey can do this now.
Here's the setup I'm using with a PS2 controller:
Left stick - Movement
Right stick - Look
Triangle - Charge
Circle - Hold
X - Action
Square - Follow
L1 - Zoom
L2 - Jump
R1 - Attack
R2 - Defend
D-pad Up - Mount
D-pad Down - Dismount
D-pad Left - Leave/Retreat
D-pad Right - Orders
Select - Next shield
Start - Next weapon
I haven't done it yet, but you could assign L3 or R3 (Button 11 or 12) for Rear Up Horse.
I haven't set up the Inventory, Character, etc. screens. This can be done by using L3 or R3 (whichever is still unused) as a Shift button in JTK, and then re-using some of the other buttons.
After setting everything up, you will need to tweak the stick settings (quite a few different ones in JTK) and mouse sensitivity in M&B to your liking. I don't think I have got it quite right for bow aiming, if someone can improve it, please post what you did.
Here's my M&B configuration file for JoyToKey. You must first Create a M&B file with JoyToKey, then you will replace the contents with my file. Copy my file into Notepad (unless you prefer to leave your browser open).
Open your jtk378en folder (the same folder should have an icon of a joystick in it). Open your M&B configuration file using Notepad. Delete the contents (if any) and copy and paste my file into it. SAVE.
