Full-screen overscan on KS1.3?
I'm trying to display a full overscan HAM-6 image at 368x462. I'm targeting 1.3 for this game, and am coding in C. I am opening a new custom screen, and a backdrop window, and loading the graphic into that window's RastPort. The window starts at 0,0. RKM says:

I had to turn the HAM image loading off in low memory situations, so on my unmodified A1000, I don't know what it would do exactly. First screenshot is of it on A3000 hardware booted to 1.3, second is UAE with emulated A3000 using 3.2.1. Any pointers? |

I found this snipped in an AmigaWorld Tech Journal article (see attachment). Basically it says people used various hacks to do this before the 2.0 ROMs. I'm not sure how to search for stuff like that. Pre-internet. I don't have any early Amiga magazines.
hmm. Maybe Fred Fish... |

In case anyone needs this in the future, the answer is basically this:
- you can't create the screen in 1.3 with any offsets - 1.3 knows about dxOffset, dyOffset, but they can't be set after the fact. - you need to create a new View, configure it, then LoadView() it into existence. A couple of examples to look at: - https://wiki.amigaos.net/wiki/Classi...ics_Primitives (look at the example under "Loading and Displaying the View") - aminet: HamPics. http://aminet.net/package/pix/misc/HamPics /* |
