From Aleksey Malov To Valerij Kozhevnikoff 24 October 2000

Greetings, Valerij! Sun 24 Sep 2000 at 15:57:42 Valerij Kozhevnikoff and All were talking on the topic of X-screen. VK> Tell someone about the subject.

VK> Thanks in advance. These, IMHO, are files for viewing in X-Color. Moreover, their length is not necessary 72 sectors. This is simply a file packed with any packer, consisting of three attribute-free speck screens (r,g,b - components). There is no source, but the task boils down to unpacking such a file by loading it at #b800 and running it (will unpack itself). Then you need to throw each frame onto the screen sequentially red, green, blue - screens. To simplify the task, you need one (for example, red) place the component on the second screen of the Spectrum. And while it is displayed throw the green component onto the 1st screen, and then after the beam throw the blue one component, not forgetting to set the necessary attributes. Congratulations, Valerij! Vivid/Brainwave^X-Project was with you. [ZX] [Sailor Moon]

Have you seen Confusion? There is a full screen ball mania effect. It's the same reception used. Congratulations, Kirill! Vivid/Brainwave^X-Project was with you. [ZX] [Sailor Moon]

Have you seen Confusion? There is AM> full screen ball mania effect. The same technique is used there. What if you think about it? For example: Red: 7 screen. copying green to 5 screen. Green: 5 screens. copying blue to 5 screen. Blue: 5 screens. copying green to 5 screen. There's not enough time to move the blue screen. If your program starts at the beginning of the green screen and moves slower beam, then you have exactly one frame. Where does the acceleration come from? In general, on 3 screens, of course, there is acceleration - for music...
