Graphics Tricks from Boomers

Arnaud Carré recently released a 4096-byte intro for the Atari STE, showcasing advanced graphics techniques that challenge the machine's bandwidth limitations. The Atari STE, powered by an 8MHz Motorola 68000 processor, supports a resolution of 320x200 and can display 16 colors simultaneously. The post delves into the use of the STE's blitter and the concept of "fullscreen mode," which allows for creative graphics manipulation despite the hardware's constraints. Carré explains the use of sprites, or "bobs," and introduces techniques like the stroboscopic effect and "unlimited bobs" to create the illusion of multiple moving graphics on screen. He also discusses the innovative method of manipulating the Atari's video signal to eliminate the safety borders around the display, effectively increasing the visible resolution. This involves precise timing and manipulation of the video chip's state machine, allowing for a new resolution of approximately 416x274 pixels. The post is aimed at enthusiasts of retro computing and graphics, providing insights into the technical challenges and solutions employed in the demoscene.
