DIP switches subject is Mega STe and TT only.


They are visible under the same address as STe Jaguar analog Joistick port.

Below you can find the outcome from my tests for my STe/ MSTe and TT:
    move.w    $FFFF9200.w,Wartosc
; RESULT MSTE: FFF9
; RESULT STE:  FFFF
; RESULT TT:  3F03


    move.b    $FFFF9200.w,Wartosc
; RESULT MSTE: Buss Error
; RESULT STE:  Buss Error
; RESULT TT:  00


    move.b    $FFFF9201.w,Wartosc
; RESULT MSTE: F9
; RESULT STE:  FF
; RESULT TT:  03
