Yup, I finally got you. :-)

I would like to make it simplier too. I really love simplyfying and my
resulting code is as simple as possible. Only the basic idea is complicated.

And I can't think of any other solution now. Actually only using this very 
special code made my demo possible at all.

As I have explained in my previous mail, the problem is, that I have to
do up to two RESPx and a HMOVE at the end of the preceding scanline. 
And then it is important that the HMOVE influences the resulting position 
of those two RESPx. So I have to do the RESPx very (too) soon after the 

And though I sometimes could do one RESPx immediately *before* HMOVE
instead, this would still conflict. 

Sorry, but I am afraid you may have to update your emu. ;-)
