Every other adapter forces you to compromise.
The Duo Ultimate doesn’t.

The Problem Nobody Else Solves

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.

⚠ Other Adapters

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.

✓ Duo Ultimate

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.

Supported Controllers

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.

Dual Independent Ports

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.

Choose Your iCode Adapter

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.
