Thanks, I tried this (I'm working on ST)
but I noticed that when setting the new screen address in the VBL interrupts, the new screen address seems to be valid only for the next frame, and not the frame that will be drawn at this VBL.
even setting the address in the VBL, I had flickering on one of my effects that was taking around 1.25 VBL to complete, I don't quite understand why, I solved it using 4 buffers swap instead of 3 .. (brute force way of solving things, but well ...)

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.
