 Re: general smooth scrolling questions

Hi icbrkr,

I'd suggest to compare the following code snippets:
LDA HorizPos ; *** get our VARIABLE ***
STA $FF07 ; change FF07 (horiz scroll)
==============================
LDA #$58 ; *** Return to "normal" horiz position
STA $ff07
==============================
LDX #$07 ; next value
loop07 STX HorizPos ; store it


Guesswork: by the symptoms you described, you are turning on PAL mode when you try to set the scroll position. (It is a good question why does this not bother YAPE?)
