Hi, I am a newbie this is my first post/ program.
I am struggling with figuring out the correct placement of HMOVE .
I have placed a sprite , but I want to move it 3 pixels to the left . When I try to load the offset , do WSYNC and then HMOVE immediately after RESP0 I get a crazy flickering screen.
can someone please help ? Does the HMOVE need t be done on each sprite scanline or once per frame? If once per frame , then where should it be placed?
I have seen several examples of algorithms for fine horizontal placement but cannot get these to work correctly either. Perhaps it has to do with the fact that I am wasting my VBLANK periods by not using timer.
Sorry for so many questions... code is attached
