Here's what I have been playing around with. My first multi directional C64 scroller. Obviously need to deal with the bottom row, my thought was to put a strip of horizontally stretched sprites over the top. Interested to hear how other devs have dealt with this.

@monteboyd switch on illegal screen mode and it goes black.

@martin_piper interesting thanks Martin! Is that a “typical” way of dealing with it would you say?

@monteboyd Yes it is a very common method because it avoids using sprites and the problems of trying to handle the previous sprite's Y position.

@monteboyd probably the best way is to inspect how games do the split with C64DebugGUI (or similar): https://youtu.be/LOUCV-x31U4?t=87
