I must disagree. It's not true, look at the example of Amstrad CPC. this computer was a 8bit system, comes out after msx2 and got a decent library of sw & games.
I must (strongly) disagree ... Amstrad's CPC464 came out in December 1984, roughly at the same time that MSX1 came out in Europe (I've got a copy of "Your Computer" from 12.1984 filled with ads to prove that).

MSX2 came out in Japan in mid-1985 and we did not see one in Europe until one year later, in mid-1986 (all this can be verified in magazines from that era).

Furthermore, the CPC464 got a (very) decent library not because of its hardware, but because it was successful due to its revolutionnary all-in-1 system (computer, monitor and storage-media).

Well, I meant that Konami would've used that screen even if they had been using an MSX2 from the start.

Probably, and they could used r18 to achieve smooth scrolling. In this type of game smooth scroll add a good quality.

About spmanbow, did you notice if konami had the usual ring buffer to make flickering the sprites?
In spmanbow appears as there are not situations where more than 8 sprites, so i suspect they have no flickering routine, that save time and allow for other vram I/O in vblank

I apologize i had others data, but the difference of one year does not change nothing. the not so successfull msx2 have it's root in the compatibility with msx1.

I have no data but i think the same problem happened to CPC+ respect to CPC, or i'm wrong?

Only when pattern enemies move at exactly the same speed as the level, how often does that happen?

I'm only referring to background, of course, like in spmanbow

Into platform games this is not a problem, the sprite could have a double speed (rush mode) when the entire screen will move and the pattern enemies would have the normal speed + the speed of the screen moving. This is useful for games that only move the screen when the main character is walking ...

@PinPong
I was going to consider an msx 2 version of our engine....
No commitment on my side, it is just a test...
Could you write and post here a code that, in screen 5, fills a screen in page 0 or 1 of 8x8
blocks taken out 256 blocks in page 2 by reading the block number from a "room" in ram.
The window displayed has to be 32X20 in a room of map_w X map_h.

So msxdev does boost MSX activity. The problem is that all it does boost is MSX1, which is IMHO a step backwards.
When MSXdev contests were concepted there was no MSX(1) activity at all, or just a few. Now we MSX lovers can say we have lots of productions each year. So it is just a step backwards for those who understands the MSX standard as something that started with the MSX2.
