Hacking Trying to map Krull controls in MAME4ALL

[WaverBoy]

Hi all,

I'm trying to map controls for Krull using MAME4ALL on my PSP 2000. I've figured out that, after the first three FIREs that are set to Auto Off, this is what the FIRE numbers correspond to:

FIRE 01 = move left
FIRE 02 = move up
FIRE 03 = move down
FIRE 04 = move right
FIRE 05 = fire left
FIRE 06 = fire up
FIRE 07 = fire down
FIRE 08 = fire right

I tried mapping 1-4 to Joystick Push and 5-8 to square, triangle, circle and X, but it doesn't work. If I map 1-4 to square/triangle/circle/X and 5-8 to Joystick Push, then I can move with the buttons and fire with the D-pad, but obviously the opposite setup would be far more desirable. Anyone have any ideas on how to get these Krull controls mapped properly? Attached is a screenshot of the useless default control mapping.

Thanks in advance for any help!
