Batari Hardware collision 30fps flicker
I had a problem for a while figuring out what to do about making my flickering sprites collide properly. Using odd frame, even frame, I found that only sprites on the same frame could collide. So I varied my flickering with one sprite alternating frames, and the other doing two frames in a row. Attached is the code and a binary. You drive sprites A and B. C and D will wrap around the vertical edges. If you touch C or D, one of your sprites will die and turn into a skull, the other will keep moving. The reset switch resets the program. Flickered sprites look horrible, but at least now I have two p0s and p1s that'll crash into each other.
