Basicly it's like Spectrum 512 but using a blitter pass instead of move.l (an)+,(an). It's a bit faster, 8 cycles per colour so the Sector One displayer manages 56 colours per scanline opposed to 48 for Spectrum.
The blitter is cycle-exact, with exception that on Mega STe, starting a blitter pass is 4 cycles slower than on regular STe.
And the blitter hogs the bus when working, so the CPU can't fetch new instructions meanwhile.

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.
