Subject: [stella] RESBL strangeness, answered (maybe) From: "Eric Ball" <eball@xxxxxxxxxx> Date: Thu, 10 Oct 2002 16:48:38 -0400 |
Fixed the kernel and did some more testing, and I think I've figured it out. It appears that the actual start pixel for the ball is at RESBL + 4 pixels. So if I want to position the ball starting at onscreen pixel 2, I have to hit RESBL at CPU clock (68 + 2 - 4) / 3 = 22. (Which, of course, wrecks my nifty 8 cycle timing loop. Sigh. But it looks like it was off anyway...) Or have I got it wrong entirely? ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
