Hey guys,
First of all, thank you for all the time you've invested in both the wiki and in these forums.
I'm grateful for the tons of great info and all the help you have given me (indirectly, from reading other topics, but still).
I'm seeing a seam at the top of the screen while testing 1942.
Now, from what I gather, it's probably a bug, but my code *seems* to be correct.
Tried to load up messen but my mono version is too old.
However I loaded up https://github.com/fogleman/nes and he has the same problem.
Now I'm not sure if this is expected behaviour, or if I truly have a problem, the timing logic can be a bit tricky, and I might just be a row behind. My implementation is based on the (skinny) scrolling and timing docs.
As such, the question is simple, is the seam supposed to be visible?
This only happens in vertical scroll. Horizontal is working fine.
I've attached the output that I'm getting and a dump of the nametable data at that point.
Thanks in advance!
