You don't actually need to have a "source screen" for clearing a bitplane (or indeed 4 planes).
Just set source address and destination address the same and set the blit_op register to 0 (target will be zeroed out) saving you a bit of ram.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
