Hi,

I'm trying noneya's VIA emulator in PICO-6502. Here's knight-rider code in a1basic.
Note I moved the base address of 6522 to $B000.

Code:
   10 POKE -20478,255
   20 K = 1
   30 FOR I=0 TO 7
   40   POKE -20479,K
   45   GOSUB 500
   50   K=K*2
   60 NEXT I
   70 K=128
   80 FOR I=0 TO 7
   90    POKE -20479,K
   95    GOSUB 500
  100    K = K / 2
  110 NEXT I
  120 GOTO 20
  500 FOR J=1 TO 10
  510 NEXT J
  520 RETURN
