During the weekend there was a demoscene Lost Party 2026 in Poland and demo-group Agenda released there a new demo for Atari XL/XE. The demo is using PAL blending graphics mode (not frame blending) to increase perceived number of colors. The link is to WASM emulator (AltirraSDL) with enabled CRT effects to get it closer to how it looks like on a real hardware. Demo requires 320KB of RAM for preloading purposes only (no effect requires more than 64KB of RAM) - on Atari, in contradiction to, Commodore 64 you cannot do well parallel loading to playing demo effects.
Happy watching and feel free to ask any questions.
