I wonder if this is because I don't yet draw sprites a scanline early. Do you know if you can reproduce it with a setup that doesn't use HDMA?

I'm sure I can't replicate it without using HDMA.

From looking at this in NBA, it does look like drawing sprites a scanline early would fix this.

I am pretty sure this is a duplicate of #1871 with just a different test ROM
