Programming like a neanderthal: Atari 2600 development
summary
Atari 2600 development centers on tight, measurable constraints: a 1.19 MHz 6502/6507 CPU, 128 bytes of RAM, 4 KB typical cartridge space (some later games use 32 KB), and a TIA video clock at 3.57 MHz so one TIA tick equals three CPU cycles, leaving only 76 CPU cycles per scanline to compute graphics. Developers use techniques like racing the beam, two/three-line kernels, register reuse and sprite multiplexing to draw mirrored 20‑bit playfields and multiple actors; the tricks enable surprising feats (Solaris on 32 KB) and explain flicker and other artifacts.
