I don't think the AKI is mappable.
AFAIK, the 49-way can't be used as a true analog with any of the converters.
The result of trying is that you end up with a stick that will jump to 49 distinct locations within the analog spectrum.
For a game like Star Wars, this means that you can't smoothly move your crosshairs to barely off-center.
You will jump from zero to a spot equal to 1/3 of the way out on an analog.
Then you will stay there until you jump to a spot 2/3 of the way out, and finally to all the way out.
While this doesn't make the game completely unplayable, it is frustrating.
Some games that originally used analog controls will play well with a 49-way though.
Road Runner jumps to mind.
It originally used an analog (hall effect) joystick, but had three distinct speeds in the game.
This equates well to a 49-way map.
