MAME4ALL PSP -- any way to map KRULL controls properly?

[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?
