Capability-sandboxed cores
An emulator core runs a foreign binary. On sigilOS it's cap-gated to exactly what
it's allowed to see — the same isolation that secures the rest of the OS, pointed at your ROMs.

Everything else in this program is a fit we're building toward. This one is real, right now: Forge is a native desktop binary for macOS, Linux, and Windows, and it's how we earn our way into the household — one enthusiast, one Pi, one perfectly-preserved cartridge at a time.
Why this is the beachhead
Gamers and hobbyists are the sharpest, most honest early adopters there are — they'll run it, break it, and tell you exactly what's wrong. They also happen to sit right on top of the hardware sigilOS loves (the Raspberry Pi) and the problems it's uniquely good at (running untrusted binaries safely). So this is where we build mindshare and prove the architecture in public — with a product people can actually hold.
What makes it different
Preservation
The signed Relic format
One file = one game: ROM + BIOS + save state, packed into a verified
Relic container that's checked before every launch. Pack once, verify
always, play anywhere.
Native, no cruft
Zero Python, zero VM
Written once in Sigil, compiled per platform by cc0 — no interpreter, no emulator
layer underneath. A CHIP-8 core already runs a real ROM as a native binary.

Runs anywhere
Desktop and a Pi 3
The same library targets your workstation and a 1 GB Pi. GPU-first
compositor, near-native dynarec for the heavier cores.
Play together
SRDX rollback netplay
A kernel-native remote lane with a rollback-netplay mode — not a bolted-on
streaming app. SRDX →
Own your library
Smart-Folder ROM navigation
Tag, search, and organize a big library with the same Smart Folders the OS uses —
thumbnails, BIOS manager, save-state gallery.
Download it now
Forge v0.1 is a native desktop preview for macOS (Apple Silicon), Linux x86-64, and Windows x86-64 — one cc0-compiled binary per platform, each with a published SHA-256. No VM, no Python, no runtime underneath. Get Forge →
Where we actually are — no hype
- SHIPPING Forge native downloads are live on all three desktop platforms, SHA-verified. The Relic container spec and verify-before-launch are real.
- A real CHIP-8 core executes ROM bytecode and renders its framebuffer as a native binary — a headless render proof today.
- IN PROGRESS Windowed cores (on-screen display + live input + audio) and the heavier systems are the next milestones, building in the open.
- EARLY v0.1 is a preview. It's honest fun, not a finished front-end — and it gets better in public every week.
Who this is for
Retro enthusiasts, homebrew and maker communities, handheld and Pi builders, and preservationists who care that a game is verifiably the thing it claims to be. If you want a polished, feature-complete front-end today, we're early — but we're real, we're native, and we're moving fast.
