It's going to take ALOT more programming than that to make this work properly.

As you have it, you will have either a 4-way stick (provided you use Q*Bert mode), or you will have HUGE deadspots on the original directions.
If UP=Up-Right, and LEFT=Up-Left, then the joystick will send no usable signal when only the Up switch is pressed.


I'm not completely sure that the following mapping will work because I haven't tested it, but it should.
It should also work on any 8-way stick--if it DOES work.

You need to map the inputs as follows:
NOTE: Red are MAME inputs, Green are Joystick inputs.

UP=(Up NOT Up-Left) OR Up-Right OR (Right NOT Right-Down)
LEFT=(Left NOT Left-Down) OR Up-Left OR (Up NOT Up-Right)
DOWN=(Down NOT Down-Right) OR Down-Left OR (Left NOT Left-Up)
RIGHT=(Right NOT Right-Up) OR Down-Right OR (Down NOT Down-Left)

Using this mapping, the original cardinal directions SHOULD send signals to 2 separate inputs (i.e. Up SHOULD trigger both the UP command, and the LEFT command).
