Well, MSX had 8-pixel step scrolling horizontally, and 1px vertically. But scrolling the whole screen usually left no time for any game of sorts, even at 25 fps! Unless it was like some cartridge games that had a blitter of sorts. Its predecessor, Spectravideo 328, was better in that respect, the video was mapped onto the main memory.
Lots of home computers had char scroll only, of course, and many no scroll register. Which meant few scrolling games, if any. It would be cool to find out the exceptions on each of those platforms!
