so wait...we still need to map input for the diagonal games even when the joystick is in diagonal mode? i thoguht the point of diagonal mode was to solve this problem...am i just lost?
Addressing MAME's (TM) odd way of describing controls for diagonal games was
not the idea behind the diagonal mode . MAME sees controls for diagonal games as a regular 4-way, just mounted differently, apparently rotated 45degrees clockwise.
The GP-Wiz49 is not exclusively a MAME controller, so this was not the goal. If you consider what must be done on an 8-way stick to effect a diagonal, you will see that you would need to position the stick properly to close the 2 switches simultaneously, and do this at every move. With a Prodigy joystick in 8-way mode this works pretty well due to the squareish mechanical restriction. But if you try it with a non-restricted 8-way. you will quickly understand the benefits of the GP-Wiz49's diagonal mode.
You need to set up the game as you would for use with an 8-way. If you do this with the diagonal mode activated, it's very easy to do. But keep in mind that the set up is where the similarity ends.
