ehenciak Posted January 30, 2005 Share Posted January 30, 2005 Hi all, Another silly question...looking at TIA's schematics, it seems that the a write to the Player 1 graphics register stores the current contents of the ball enable register. This appears to have something to do with the vertical delay of ball. Is this Player 1 graphics / ball relationship mentioned anywhere in the Stella documentation or am I missing something? Forgive my ignorance! I sent this without analyzing the circuit too much since I'm working hard on something related to this right now ! Thanks!

ehenciak Posted January 30, 2005 Author Share Posted January 30, 2005 Uh, make that the inversion of the current ball enable register is stored when the player 1 graphics register is written. Sorry about that! Ed Quote Link to comment Share on other sites More sharing options...
Robert M Posted January 30, 2005 Share Posted January 30, 2005 I am sure you are seeing something having to do with the vertical delay function for the Ball. It's interesting that you mention it seems to be tied to P1. I have never used that function, so I can't offer more info. Sorry. Quote Link to comment Share on other sites More sharing options...
Thomas Jentzsch Posted January 30, 2005 Share Posted January 30, 2005 Yes, it is P1 and no, IIRC it is not explained in the Stella Programmer's Guide. Quote Link to comment Share on other sites More sharing options...
