problem with numpad butons in nulldc

[hepe]

hello
i tried playing Dead or alive2 on nulldc 1.04
and it has error when i set player 's buttons to numpad keys (although i turned numlock on)

i set like this image

i set y (the x buttons on nulldc ("x" buttons of xbox) ) to numpad 4
x to numpad 5
b to numpad 6
a to numpad 3
digitalup to up
digitaldown to down
right to right
left to left


when I holds these 3 buttons : "Y", "MOVEBACK" button at once
(RIGHT,NUMPAD3 ) AND PRESS "A" (NUMPAD 4) button, it can do "kick" function as it should
but if i change these buttons to "character" key on keyboard (such as "q","w","e" key )
it works

it 's very annoying when playing 2 players on keyboard

i even tried "keyboard remapper" to remap these numpad key to "character key" (such as "q" ,"w" ,"e" ..) and reboot the pc but it does not work)

it still does not work with gamepad when i bind gamepad buttons to numpad keys

i have no idea what 's the problem on numpad key with nullDC ?
please help
thanks :D

thank you
I already had gamepad , i just wonder if anyone encounter this problem ,too ,because i tried mappping the numpad ,arrow keys . . . to a,b,c .. keys

There is another big problem :
Even when we have the gamepad and config the buttons to ,b,c,d . . . keys (normal keys)
when a player holding at once up,forward (forward to the enemy),down buttons ,=> both player can't attack
The same problem will happen when holding down, backward ,forward keys
does anyone have this problem when playing DOA2 on nullDC ?
