Not all MSX2+ computers had it in them, because it wasn't a required part of
the standard. There even is a game (Twinkle Star) which uses the MSX2+ video
chip, but will crash your computer when you enter level 2 if you've got a
MSX-Music in it. It's really stupid, since the game itself does have
MSX-Music music (is that a pleonasm?). But it indicates that the programmer
had an MSX2+ computer without MSX-Music. Or maybe he used a Panasonic-only
MSX-Music feature (read: the SRAM), which he suspected to be there when an
MSX-Music was detected. Anyways, the game doesn't run on my MSX2+ after the
first stage. It does on my MSX2 without FM-Stereo-PAK, but the second stage
uses the horizontal scroll feature, so it looks like crap on a v9938 (it
doesn't check for it, by the way).
You know, there is actually one really great shooter which is one of my
favorites (I will list it in my top-30): Sea Sardine!!! The only shooter I
know which uses the MSX2+-scrolling. It's really awesome. Is the second part
ever finished, and if so, where can I get it???

8-pixel scroll @ v9938, smooth scroll @ v9958. That's the formula.

I agree. But those are games from the MSX1-era... Even screen 5 wasn't there
yet. It is impossible to code a smooth horizontal scroll (with colors on the
screen) on an MSX1 computer.
