Sfotty Pie is a comprehensive toolkit for the 6502 processor, bringing the Atari 8-bit computer and related systems to your browser. It includes a cycle-accurate 6502 CPU core, a full Atari 8-bit emulator supporting the 400/800, XL/XE, and XEGS models, and a 6502 assembler. The emulator handles most games with accurate video and audio, works on mobile devices, and supports joysticks via keyboard, gamepad, or touch controls.
Built in TypeScript, the emulator emphasizes accuracy over performance, with nearly all components cycle-exact. It ships with open-source replacement ROMs so it boots without proprietary firmware, stores games and disk images locally in your browser using IndexedDB, and includes features like a command palette and gamepad-friendly game launcher.
