I am trying to program an engine test for a 2600 version of Zuma that uses the driving controllers, but I can't figure out how to program a playfield swicth at the press of a fire button.

Driving controllers use the same registers as the joystick...SWCHA for the knob (reading bits 4&5 for the left port and bits 0&1 for the right), and INPT4 and INPT5 for each trigger - bit 7 on (negative) = not pressed.

IMO Zuma seems to be quite advanced for a beginner project (if this is your first). Good luck.

I'm Afraid that didn't help Here is my current code

gamescreen
playfield:
......XXXXXXXXXXXXX.......XX....
.....XX...........XX......XX....
....XX.XXXXXXXXXX..XX....XX.....
...XX.XX........XX..XX...XX.....
..XX..XX.XX.....XX..XX..XX......
..XX..XX.XX.....XX..XX..XX......
..XX..XX..XXXXXXX..XX..XX.......
...XX..XX.........XX..XXX.......
....XXX..XXXXXXXXXX..XXX........
.....XXXX..........XXXX.........
......XXXXXXXXXXXXXXXX..........
end
COLUBK=$0A
COLUPF=$06
drawscreen
if joy0fire then goto gamescreen

Hope this helps

>.<

So, you only want to goto gamescreen if the fire button is pressed? what say, happens if you don't press the fire button.
