Posted 31 July 2009 - 08:58 PM

so i need to change the patch that friedgold used to map the dpad to the arrow buttons, and the a button to return.

i need to set it up so that:
Start = Return
Back = Escape
Dpad = Arrows (already implemented)
A = Q
B = W
X = A
Y = S
White = Z
Black = X
Right Thumb Click = F1

also, i need a way to map a second controller (/dev/input/js1) to the following:
Start = \
Back = Escape (same as first controller, is this possible?)
Dpad:
Up = O
Down = ,
Left = K
Right = L
A = [
B = ]
X = ;
Y = '
White = .
Black = /

so first off, is it possible to map seperate controllers to different keys? here is the xpad-keyboard.diff:

/*
*  driver history
* ----------------
*
* 2003-05-15 - 0.1.2 : ioctls, dynamic mouse/rumble activation, /proc fs
*  - added some /proc files for informational purposes (readonly right now)
*  - added init parameters for mouse/rumble activation upon detection
*  - added dynamic changes to mouse events / rumble effect generation via
*    ioctls - NOTE: this requires a currently unofficial joydev patch!
*
* 2003-04-29 - 0.1.1 : minor cleanups, some comments
*  - fixed incorrect handling of unknown devices (please try ir dongle now)
*  - fixed input URB length (the 256 bytes from 0.1.0 broke everything for the
*    MS controller as well as my Interact device, set back to 32 (please
*    REPORT problems BEFORE any further changes here, since those can be fatal)
*  - fixed rumbling for MS controllers (need 6 bytes output report)
*  - dropped kernel-2.5 ifdefs, much more readable now
*  - preparation for major rework under way, stay tuned
*
* 2003-03-25 - 0.1.0 : (Franz) Some Debuggin
*  - Better Handling
*  - X/Y support, Speed differenting
*  - Landing Zone, Dead Zone, Offset kompensation, Zero-adjustment, .... aso.
*  - Removed Wheel handling in Mouse Emulation .. sensless..
*
* 2003-01-23 - 0.1.0-pre : added mouse emulation and rumble support
*  - can provide mouse emulation (compile time switch)
*    this code has been taken from Oliver Schwartz' xpad-mouse driver
*  - basic rumble support (compile time switch)        EXPERIMENTAL!  
*
* 2002-08-05 - 0.0.6 : added analog button support
*
* 2002-07-17 - 0.0.5 : (Vojtech Pavlik) rework
*  - simplified d-pad handling
*
* 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
*  - verified the lack of HID and report descriptors
*  - verified that ALL buttons WORK
*  - fixed d-pad to axes mapping
*
* 2002-07-14 - 0.0.3 : (Vojtech Pavlik) rework
*  - indentation fixes
*  - usb + input init sequence fixes
*
* 2002-07-02 - 0.0.2 : basic working version
*  - all axes and 9 of the 10 buttons work (german InterAct device)
*  - the black button does not work
*
* 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
