There was another topic that led me to the config.val file which can be opened up in the HxD hex editor.

I am just above being a newbie at it through messing around with widescreen & 720p Xbox emulation and the like. This is my slightly cleaned up "homework" and where I leave off at because I just don't have the experience necessary to solve getting the preferred keyboard controls and I can handle movement defaults and my chosen custom enough to play.
(I also learned that pressing the same input again in the config menu deletes that input)
--
W = 77
A = 61
S = 73
D = 64

Officially changed inputs and options move 4 places down from their default spot in the val file after changing and there are 17 spaces between input name and the chosen button.

Putting down into the UP direction appropriately makes you go backward. Putting up into DOWN switches both down and right to LEFT and OPPOSITE respectively.

10 11 04 Up
