Every classic controller.
One USB. Zero compromise.
From Atari paddles to Intellivision discs to Vectrex analog sticks — the Duo Ultimate translates 13+ vintage controllers into rock-solid USB HID input. Built around the dual-core RP2350 and a proprietary jitter-free analog pipeline.
Every other adapter forces you to compromise.
The Duo Ultimate doesn’t.
Paddles that actually feel like paddles.
Vintage analog controllers were never meant for a USB world. Most adapters pass raw noise straight through — your cursor jitters, your aim drifts, your paddle hand twitches in games it never should. Our proprietary jitter-free analog pipeline cleans up the signal in real time without adding latency.
Noisy. Twitchy. Drifty.
Raw analog readings bounce around even when your hand is still. In emulators this shows up as cursor jitter and ghost inputs that wreck precision games.
Smooth. Stable. Precise.
The jitter-free pipeline filters noise the moment it appears, then applies your sensitivity and acceleration curves. You feel exactly what you input — nothing more, nothing less.
13+ classic controllers. One adapter for all of them.
No more juggling four different dongles. Plug Atari, ColecoVision, Intellivision, Vectrex, or Sega Genesis controllers into the same two DB9 ports, switch presets, and play. Each port can run a completely different controller type at the same time.

A live, animated color LCD that shows exactly
what your controller is doing.
Three display modes. Watch your input come alive.
Toggle between an animated controller view that mirrors every stick movement and button press, an advanced HUD with per-port diagnostics and preset details, or display-off for a clean setup. It’s the kind of feedback you didn’t know an adapter could give you — until you have it.
- Two configurable RGB indicators show port activity, preset, and USB mode at a glance
- 10-channel polyphonic audio for menu feedback, alerts, and built-in games
- 5-direction hat + 6 fully programmable buttons, each with up to 3 simultaneous functions
Wait — it plays games too?
Three full mini-games run right on the LCD, controlled with the built-in buttons or any connected controller. Trackball into Iron Dome for analog crosshair control. Paddle into Brick Bash. Even high scores upload to a community leaderboard.
Two ports, completely independent.
Run a joystick on Port 1 and a keypad on Port 2 — exactly as the original Star Raiders hardware intended. Or unlock Split Mode: read 4 paddles across both ports as 4 independent USB gamepads so MiSTer, RetroPie, and Batocera see them properly for multiplayer Warlords and Kaboom.
Your cloud companion. Zero installs.
A free, web-based control center that connects to your adapter directly through Chrome or Edge via WebHID. Manage 10 on-device presets plus up to 100 in your personal cloud vault. Over-the-air firmware updates, community leaderboards, and seamless device transfer if you sell or gift it.
- Sign in with Google or one-time email code — no password to manage
- Smart conflict detection when device and cloud presets diverge
- Built-in firmware recovery mode — flash and rescue from any state
A standard USB HID device. Drivers? Never.

Three adapters, one is right for you.
All three iCode adapters share the same proprietary jitter-free analog pipeline. The Duo Ultimate is the full-fat flagship — every controller, every feature. The SE keeps the dual-port hardware but trims the LCD and extras. The Uno is the entry point.
