Anyone know how to match the controls to the Hori arcade stick to match the original stand up cabinets?

There is no arcade release for Soul Calibur IV.

but they never changed the buttons setup from the previous ones from the arcade. I just want to know the button lay out that would be similar to the previous soul calibur to the hori stick.

just make it to how ever you want it.  Whatever feels comfortable to you.

The arcade setup for Soul Calibur games has always been:
ABK
G

So you have ABK in the top row of buttons and then G mapped to the bottom left.  I always use the official arcade setups too, and its great :D

thank you trip master munky
