I heard that as well. Old consoles and home computers had difficulty with scrolling, the MSX scrolling issue is also seen in the Sega SG-1000, Colecovision and the Casio PV-1000 as well, so it wasn't unique to the MSX. It's hard to believe but at the time of it's release the Famicom was a graphical powerhouse unlike anything seen previously.

I really got into the MSX since about 2007-2008 when I started to emulate it, learn about it and atart learning about the community and MSX programmers and game developers at the time. I got my MSX Turbo R around 2008 I think but only had a small collection until about 2020 when I really got into it during the pandemic
