I wrote the scroll code over a couple of hours after getting the left and right border overscan working (finally!). I put in the top border bit to get over the loss of screen. I always assumed STs were all the same. All I know is that my code works on my ST so I'm happy :-) But no matter, I'm sure any hackers who've seen my code and understand the principles can sort out the technicalities. >German software house Thalion that employs the guy that invented sync scrolling >and some more VERY (EXTREMELY) talented people is busy working on some very >technical games that use Sync scrolling.
