Strange sideborder error
So I've put some sprites in the sideborder and multiplexed them.
It seems that the sprites starts displaying one scanline before expected, and the output is garbaged bytes - but only when they're in the right border and only when they're about 24+ pixels from the edge of the normal screen.
Anyone has the slightest idea why this is happening?

IIRC, I used the method that Danzig is describing for my sideborder dypp in The Barn 3. OTOH, the bordersprite usage in that one is simple, so any method would work.

the solution I used is somewhat "quick & dirty", but it
worked for me at the time:
If a sprite is in the problematic area (check X coord)
then close the border on the 1st line of the sprite.
It has some visible side-effects when another sprite is
displayed in the border on the same line, but that can be
improved with some sinus tweaking..
You can see an example of this in the side-border scroller
in Insomnia. |
