Retriggering ball changes the ball size

[lucienEn]

Hi, I'm testing TIA_HW_Notes.txt about retriggering the ball and I get different results than described in Stella:

 

"Actually on my 2600jr (long rainbow), setting the ball size to 8 pixels results in solid colour when it's reset every 9 pixels (this might just be colour bleeding, I'm not sure)."

 

Now when I try this on Stella I get width truncated for 2nd redraw: notice the 2nd line is now truncated, if I wait it keeps the size. Any idea?

 

Code:

    sta WSYNC

    sta HMOVE

 

    sta COLUPF       ; Color playfield/color

    sty ENABL

    nop
