I just want to mention I'm reading your blog and it is amazing, I can't believe how much I'm learning in such a short time

Thanks, I'm busy writing the second part of the "Hello world!" tutorial at the moment. Might be to simple for you as you are already busy with VDP, scrolling, etc.

ChibiAkumas has great tutorials on Youtube, a website and has written a book about Z80 programming for beginners: https://www.assemblytutorial.com/

ChibiAkumas is a fantastic source of information for many (really many) platforms, BUT why such exotic color scheme? It's extremely hard to read.

Okay, so the 8 pixel scrolling, famous in games like Nemesis, this was because each element of the background was actually a colorful character?

Are you saying that every element of the background in Konami games was a specially designed character, loaded in by the computer from a character set on the ROM, and then the background played out like a PETSCII game essentially, while the other layers displayed the sprites?

Smooth scrolling is possible, with some compromises. There are several techniques to achieve it: easier on vertical movement but also possible on horizontal (you have to manage color limits in this case).
