Hi guys,

So I've pretty much finished my first level in my NSMB hack, and now I'm looking at making my second level...but before I do, I want to ask a question that has been heavily on my mind lately.

How are sprites 198 and 199 ("in air vertical scroll stop left" and "in air vertical scroll stop right" respectively) supposed to be properly used in a level? I wish I was able to understand their inner workings, but that won't be easy without a little help.

Thanks in advance.

I explained it a while ago here, take a look:
