Hi Adam, > Well here's my first attempt at something on the 2600, but I ran into a > teeny problem.

I'm not sure if > there's something fundamental I'm missing about how the missile works. If I understand you correctly you're expecting to the missile graphic to continue down the screen. If that's the case then it would be because you're setting RESMP0 to #$02. When you turn on bit 1 (i.e. #%00000010) then the missile will be locked to the center of it's corresponding player and also be disabled. If you use #$00 then the missile can move independently of it's player and it will also be enabled. Disregard all of this if this is not what you meant ;) Take care, Dennis ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
