Sanwa Clone over USB Encoder using 5 pin cable. With the 5 Pin cable we cannot re-assign directionals.
Pulled out Square restrictor plate and put in Octagonal Restrictor Plate.
To Fix Left and Right we ONLY need to change Axis from 1 to 0.
To Fix up and Down Axis we need to change Axis from 0 to 1 AND swap negative and positive.
JSCal Links
So It appears we MIGHT be able to correct directionals at driver level using JSCal -U

Just rotate from these 4 screws to get up down left right correct.
