@ -6,11 +6,18 @@ Kung-Fu Master / Spartan X (Tecfri bootleg)
single PCB with 2x Z80
similar looking to the '1942p' and 'spyhuntpr' PCBs
P2 inputs don't work
DIPS etc. are near the 2nd CPU, should it be reading them?
visible area is 16 lines less than the original, otherwise you get bad sprites
but I think this is probably correct.
