Hey I found that CALL $69 initialises sprites, but also puts all the spriteinfo in the bottom of screen 1 (or is it screen 0?)?
So if Id build a background in page 1 and THEN initialize the sprites (call $69), then a part of the background (in the bottom) is altered by the filling of the spritestables.
The CALL $69.....
what does it do exactly?

It's the erotic mode of MSX, especially for Sonic  |

You could look it up in the BIOS listing on HansO's (I believe) website.
Or trace the call 69h routine.

Cool
I found Hans Ottens Bios listing.
Now I know what happens when call $69 is made.
Pretty cool document !!
When calling $69 basically the spritetables are erased,
which in my case caused the background to be partly erased as well !!
Problem solved!

in a lot of cases the Bios routines serve me with great joy.
next to that it does save me some space in my listing.

well, 2 postings will not save database space dude. 
True but it's always a good idea to learn how to work the machine yourself. I only use the bios call to change to screen 5 for example. (and some slotswitch routines)
yup, I'm a control freak

Nah, if you were a control freak, you'd change the screen manually as well. Like me! |

since setscreen is only done once per project I wouldn't bother....altho I must admit I'd rather do it myself, but hell.

norakomi wants to do a SCREEN5/SCREEN4 split... and then he has to set those registers himself...
