Someone asked me for more information on how to set up an 8-way to play Q*Bert in another thread, so I thought I'd start a new thread for the search function.
To set up your 8-way for Q*bert, go to the Inputs for this game menu, click on each of the following, and then press BOTH directions you want mapped to that function.
Up=Up AND Right
Right=Right AND Down
Down=Down AND Left
Left=Left AND Up
Once you have these set, you have to push UP-RIGHT on the stick to send an Up signal to the game, etc...
That makes the 8-way behave exactly like a rotated 4-way stick.
This works BEST with a stick that has corners (T-Stick, Happ Comp, etc...) because the square restrictor on the stick will guide you to the corners; but it will work WELL on any 8-way stick.
