; Goal: to turn controller button samples, incoming on the x register each
; frame, into three variables:
;   - cur, which represents the current state of the controller buttons
;   - prs, which represents the buttons pressed this frame
;   - rls, which represents the buttons released this frame
; 
; Example:
;   x                 cur               prs               rls
;                     ................  ................  ................  <- initial values
;   ...........1....  ...........1....  ...........1....  ................
