I've managed to figure out how to map a diagonal direction onto a key. With a custom key config you can assign two directions (or button presses) to any key. So you can have up and left on the Q key for example.

Download and edit this file http://drnoksnes.garage.maemo.org/DrNokSnes.txt

using the following:

22=Delete 24=Q 25=W
26=E 27=R 28=T
29=Y 30=U 31=I
32=O 33=P 36=Return
37=Ctrl 38=A 39=S
40=D 41=F 42=G
43=H 44=J 45=K
46=L 50=LShift 52=Z
53=X 54=C 55=V
56=B 57=N 58=M
59=, 60=. 65=Space
111=UP 113=LEFT 114=RIGHT
116=DOWN

You can map a diagonal direction to a key by assigning two commands to one key eg.


scancode=24 (The Q key)
button=LEFT
button=UP

Place the config file in ~/apps and in the DrNokSnes control settings select the option No controls/Use config file
