Hi Everyone! :)
I'm currently working on a hack for Little Nemo Dream Master for the NES and it's ready for release. However, there are a few things that could be fixed to polish the hack further, and one of them is this:

Does anyone know how to fix the flickering line thing that's in many NES games?

Here's what I'm talking about:


It appears when there's a split screen and the flickering line appears between the 2 split screens. This happens in many games also such as Mega Man 3, etc.

Does anyone know how to fix that?

Any suggestions or pointers would be much appreciated! :)

Thanks!! :)

Take a read at this https://nesdoug.com/2016/01/15/24-mmc3-bank-switching-irqs/
Hey nesrocks and thanks!! :)

I quickly skimmed through the link and man this is way over my head...at least for now.
I think I'll just release the hack for now as fixing this might take quite some time. I can always upload an update to the ips at a later date.

Thanks again for your help!  :thumbsup:
