Hello, RetroRGB! Chris from Displaced Gamers here.
I’ve released a new video that focuses on the basics of NES scrolling and uses Super Mario Bros. as an example.
While doing research for this project, I found many new NES developers struggled a little bit when it came to understanding Nametables and Mirroring. This video makes an effort to highlight the differences between the contents of VRAM (physical nametables) and how we address them (logical nametables) in addition to scrolling.
So – A quick setup for our background tiles followed by how the camera is positioned during Vertical Blank.
Scrolling itself is pretty easy! I hope you will check it out.
