On MSX2 and higher you can change the palette in each screen, including the traditional MSX1 screens 0, 1, 2 and 3.

Screen 4 is probably the sole mode where msx2 can move large objects interacting with teh player and scroll the level

Screen 5 needs too much cpu/vdp power to have scrolling and software sprites.
Actually, maybe, a pure vertical scroller could allow double buffering for software sprites.
No game has ever done that IIRC, the games I know usually stop teh scrolling when software sprites start moving

What about sonyc? That is a screen 8/9/10/12 game that does horizontal and vertical scrolling.

Sonyc = MSX2+ = Hardware scrolling = too bad for MSX 2 users

I have just looked at the manbow screen on pauze and I just stared at it in absolute amazement. Are the makers of this artwork human?

It should be possible to scroll in screen 5 if there would be no backround at all. Then the new tiles you copy in from the other page would not take too long to get copied in on the right 8 pixels of the screen. Without hw scrolling the backround would be impossible I guess.

But if I understand the story right. In screen 4 you just have to flip the right bits and the tiles are there since they are allready drawn in the tile map.

You just draw all the tiles to the screen, scroll 8 pixels (hw), draw all the tiles to the screen with the new map offset, scroll 8 pixels etc. etc.

Yep, that's the beauty of it Smile It saves massively on drawing time, as well as cutting the space per tile in half (compared to screen 5) while retaining a pretty reasonable amount of color. Very easy to work with.
