Here it is.. 4 non flickering, single scanline resolution sprites, with no vertical restrictions. The biggest drawback is that the two fake-sprites can't be positioned too near to the borders (there must be about 30 pixels). Also, this technique is very memory-hungry, and for this reason it is not suitable for sprites which have a long vertical range. Moreover, there's almost no time left in the kernel for color changes or to enable-disable the ball. However.. this could be a good starting point for a platform-based game. This kernel could be reused more times to draw a stack of platforms, and between the platforms one could reposition the sprites and change the playfield. Hmmm.. Let me know!
