Bringing Atari 8-bit emulation to modern Apple platforms.
Fuji Concepts is dedicated to preserving the Atari 8-bit computing experience on today's hardware. From macOS desktops to Apple Vision Pro, we build emulators that are faithful to the original hardware while taking full advantage of modern platform capabilities.
The Atari 8-bit platform — the 400, 800, XL, and XE series — represented a golden era of home computing. Its custom chipset (ANTIC, GTIA, POKEY, PIA) delivered capabilities years ahead of its time. Our goal is to keep that legacy accessible, accurate, and enjoyable.
Fuji Concepts builds on the Atari800 open-source emulator project — one of the longest-running emulation projects, with roots going back to 1995. Our work extends this foundation with modern macOS and visionOS integration, Metal rendering, Swift interoperability, and platform-native user interfaces.
The flagship macOS emulator, formerly known as Atari800MacX. Full-featured with Metal rendering, 25 machine configs, 160+ cartridge types, expansion hardware, and a built-in debugger.
Purpose-built for Apple Vision Pro. Spatial display with visibility compositor, Bluetooth game controller support, and immersive audio — Atari emulation in your space.
A lightweight, Swift-first Atari emulator for macOS. Streamlined UI with native SwiftUI controls and a focused feature set for casual use.
The modular, feature-rich variant. Plugin architecture for expansion hardware, advanced debugging, and community-contributed extensions.
Secure networking infrastructure. FSSP protocol for Telnet BBS access, TNFS file servers, and multiplayer netplay over encrypted transports.
