marc.hull Posted April 25, 2011 Share Posted April 25, 2011 A few VDP/Sprite questions..... When is the sprite/sprite collision bit set ? at the end of the frame or when collision occurs on the scan line ? If using the VDP interrupt I assume the data is made available in the scratchpad only after each frame(a no brainer but just making sure..... correct ? If testing the VDP status directly with the ISR disabled do you need to wait for the end of frame or can you test it reliably at any time without missing collisions at the bottom of the screen? Does the start of a new frame reset the collision bit ? Quote Link to comment Share on other sites More sharing options...
