#Ultima iii altirra full#

I've always wondered why bricks in the original Apple II versions are purple instead of orange, which is available on the Apple II. In Ultima III and Ultima IV the differences between the C64 and Apple II graphics aren't that significant (the translator, 'Chuckles', mainly tried to replicate the Apple II graphics), although it is nice to have red bricks and other additional colors being used. 8 bits per 'character' translates to 2 4-bit (any of 16) color codes per 8x8 block of pixels. Interestingly, the color map doesn't come from the dedicated color memory connected to the VIC-II chip, but rather the character-fetch DMA process. So in this mode, the C64 is both the most colorful and highest in resolution.

While the C64 can't quite replicate every which way the Apple II distributes color pixels, overall it offers any 8 colors of its 16-color palette to each tile at full resolution (16x16 pixels for each tile and 320 pixels across the screen), while Apple II and A8 pixels are double-width (placed at the full resolution, but ultimately still blockier). That limitation works out quite well for a tile-based game like ultima, and the C64 version is the most colorful of the 8-bits computer versions I think.Ĭorrect. The C64 version of the Ultima games do not use artifacting, C64 hi-res mode can place 2-unique colors in each 8x8 on screen block I think. That limitation works out quite well for a tile-based game like ultima, and the C64 version is the most colorful of the 8-bits computer versions I think.

Weren't the C64 versions done in a high-res mode similar to Apple and Atari too? In any case, I've been meaning to track down that art program again, if I find it I'll post it and you can see for yourself.īut to the Ultima stuff, sure, the Atari version doesn't use as many artifact colors as the Apple version. Regardless, who cares if dithering is used if it works?!?īut yes the program did use dithering patterns like checkerboard, etc., to make for example a fill of red and blue checkered dither to make a 'purple' color, and in fact had an entire page or more of patterns to choose from, it also created more artifact colors like a yellow and light-green and pink (as solid looking on a composite screen as the basic red/blue or green/purple artifact colors) among others through choices of paint brushes with special pixel placement.

And yes, I see the quotes, on true, which only makes the statement more ridiculous to me. Really?!? I got news for you, ALL artifact colors are FALSE colors.there aren't any true colors.
