I must correct my previous post, the artifacted colors you should see in Ultima IV are Blue water, but the other isn't quite Green forest, it's more of a Brown earth tone that's hard to describe in one word that I know, any suggestions? Atarimania screenshots attached to "Ultima V" (unfinished, unreleased) show this color well. Don't blame me, I'm just a Comment from a Guest User. Now I'm hopelessly Not Sure (about green and purple artifacts emitting from One of my Ataris).
My 800XL was reserved for Work, and I solved Ultima IV on my model 800.
#ATARI800MACX SOUND GENERATOR#
The Green and Purple scheme results from a generator phase shift of half a pixel. Of course the various video generators in Atari can be phase tuned to make different artifact colors. Wikipedia has an article named "Composite Artifact Colors", subheading "Hardware", Atari 8bit gets one paragraph, the last paragraph, and it says to expect "blue and red" colors.
#ATARI800MACX SOUND HOW TO#
Its author may have been an Englishman who needed to research how to draw, and what he read might still be online today. The oldest most primitive emulator I have from 1998-99 has only one color scheme: blue and rich red, Ultima IV gets red water and blue terrain.
#ATARI800MACX SOUND PATCH#
There's so many draw errors in pre 2006 artifacting that rather than patch things the author made "new" artifacting but with silly pastel colors, and introduced new bugs which never got fixed (see Stellar Shuttle). Why is Blue water (in Ultima IV) now termed a Reverse mode, and what's special about the date 2006 relative to Atari 8 bit for such a profound change to be made. 2006 and beyond saw the name change to "XL/XE" artifacting and then Blue Terrain!, the mode which draws Blue water in U4 is now called Reverse, and this is why Reverse XL/XE is listed first and so-called normal XL/XE colors is listed 2nd, because the list didn't change, only the names did. Hi res card games notoriously want reddish suitesīefore 2006, emulator "Atari800MacX" named its default artifact colors "Blue/Brown" and Ultima IV got blue water. Pinball Construction Set & files created by PCS Lode Runner, Championship Lode Runner - reversed? Hard Hat Mack - reversed programming & screenshots Galaxian by "XXL" (an Apple II conversion) Music Construction Set (in Utilities section) ATASCII Character Set is one such example! I want to tag Ultima here with a good list of other "High Resolution" programs having artifacting, not a complete list.įirst there are hi res program not meant to be seen with any artifacting, often made recently in our post-CRT era, or they intentionally draw hi res in such a laborious way as to minimize any artifacting. The Atari800MacX 5.1.0 is available following the link below.Sorting out what went wrong with artifacting has made a little mess of comments here, thanx for being understanding. Fixed issue with Disk Sector editor where after doing a Goto Disk sector, the up and down arrows used the old location.Replaced deprecated MacOS API calls, to ease porting to future MacOS versions.The shift will go back to unpressed only if another Ctrl key was pressed. Fixed a keyboard issue when using a Ctrl+Shift combination, where the shift key state was stuck pressed after both keys were released.Fixed issues with keypresses still being issued along with joystick/trigger motions when using Keyboard joysticks.This feature was in 4.x versions, but had been removed in 5.x versions.
