Firmware Updates for iCode Uno and Duo Ultimate

iCode Duo Ultimate USB – Version 2.2 H1

Sticky rapid fire, custom joystick direction mapping, an emulator-friendly Driving mode, and smarter keypad defaults

Sticky Rapid Fire (NEW)

• Hands-free auto-fire — one of our most-requested features. Hold a rapid-fire button for 2 seconds and it now latches: it keeps firing on its own until you tap the button again to stop. No more holding the button down for a whole level.
• Per-button and easy to set. When choosing a button’s rapid-fire rate, pick the new SF (sticky) option instead of RF. Works for both your controller’s fire buttons and the device’s own buttons.

Joystick Direction Mapping (NEW)

• Remap each joystick direction independently. A new Directions section for the Atari Stick lets you assign Up, Down, Left, and Right to whatever you want — any gamepad button, direction, or action. By default they stay as Up/Down/Left/Right, so nothing changes unless you choose to change it.
• Turn your stick into buttons. Paired with Buttons-Only function, the four directions can be mapped to gamepad buttons — handy for menu navigation, fighting-game layouts, or games that expect buttons instead of a d-pad.

Driving Controller — Raw Output Mode (NEW)

• Better support for emulators that decode the driving controller themselves. Some emulators — such as Stella 7 with its “allow all 4 directions on joystick” option — prefer to read the driving controller’s raw signal and do their own decoding. The new Raw toggle in the Driving section sends those two raw lines as independent gamepad buttons so the emulator can handle the rest.
• Fully additive — nothing else changes. Your normal analog / d-pad driving output and the on-screen animation keep working exactly as before; Raw mode just layers the two extra button signals on top. It’s off by default — turn it on and map the two buttons to your emulator’s driving inputs.

Directional Keypad Defaults

• Keypad keys 2/4/5/6 now act as a direction pad out of the box. On a fresh setup, keys 2/4/5/6 default to Up/Left/Down/Right — giving every keypad controller a built-in directional cluster. You can still remap any key however you like.

Upgrade Notes

• Atari Stick users — please read. The Stick now reads its four directions from a remappable Directions section. On an existing setup these slots may carry old values, so if your stick stops moving after updating, open the new Directions section (in the menu or iCodeHub) and set Up/Down/Left/Right back to their matching directions.
• Vectrex users: Button 4’s storage location changed in this release. After updating, re-check your Vectrex Button 4 mapping and set it again if needed — it may read as unmapped.
• Keypad users: if you reuse a single preset’s keypad across different consoles, double-check your keypad key mappings are still what you intend after updating.
• iCodeHub fully updated to expose all of the new 2.2 options.

iCode Duo Ultimate USB – Version 2.1 H1

Vectrex Controller support, improved USB compatibility, and refinements across the board

Vectrex Controller Support (NEW)

• Plug in your Vectrex controller and play. Full support for the analog X/Y joystick and all four face buttons. No coupler or extra accessory required — just select Vectrex from the Console menu and you’re ready to go.
• Smooth, accurate stick response — the firmware reads the Vectrex stick directly for clean, linear movement across the full range of motion.
• Per-controller calibration — a built-in calibration routine lets you fine-tune the stick to your specific controller in seconds. Captures are saved automatically and persist across power cycles.
• Familiar configuration options — Resolution, Deadzone, Jitter Control, Jitter Averaging, and full per-button action mapping with rapid fire, all available right in the menu.
• Live diagnostic overlay — optional on-screen display of stick position and calibration values for tinkerers and troubleshooting.

USB Compatibility

• Improved compatibility with a wider range of host systems. Earlier versions could occasionally have trouble starting up on certain older systems and specific configurations — particularly some Raspberry Pi and Linux setups. This release reworks the USB connection sequence so the adapter is reliably recognized across a broader range of hosts.
• Better recovery from connection hiccups — minor disturbances like cable bumps or brief host pauses no longer interrupt gameplay; the adapter recovers gracefully and keeps going.
• New on-screen USB indicator — when Diagnostic Heartbeat is enabled, the indicator now shows USB connection state at a glance, making it easy to tell whether the host has recognized the adapter.

Other Improvements & Polish

• Missile Command speed tuned — gameplay pacing tightened slightly for a more responsive feel.
• iCodeHub fully updated to support all 2.1 functionality, including the new Vectrex controller settings and calibration data.

iCode Duo Ultimate USB – Version 2.0 H1

Major update — Atari 5200 Controllers, Auto Center for Trackballs & Driving, and the all-new Jaw Cruncher mini-game

Atari 5200 Controllers Support (NEW)

• Atari 5200 Handheld Controller support — full 5200 stick experience via Single or Dual Coupler accessory. Analog stick, dual fire buttons (Fire A/B), Start/Pause/Reset, and the 12-key keypad — all fully configurable through the menu and iCodeHub.
• Atari 5200 Trackball (CX-53) support — native CX-53 trackball with automatic detection. Reads the analog tachometer signal directly through the 5200 coupler.
• Single vs Dual Coupler auto-detection — Single coupler uses both ports for one controller (full keypad). Dual coupler enables two controllers simultaneously (less the keypad). Firmware detects which coupler is plugged in and switches behavior automatically; no menu juggling required.
• Auto preset switching — when a coupler is plugged in, the firmware automatically switches to the first matching 5200 preset and reboots cleanly. Auto-reverse on unplug avoids stranding the user in 5200 mode after the coupler is removed.
• Visual feedback on LCD — live overlay showing stick deflection, fire/start/pause/reset/keypad button states for both Single and Dual layouts.

Auto Center — Play ANY Game with Your Trackball or Driving Controller (NEW)

• Unlock games your trackball or driving controller never officially supported. Auto Center transforms these classic input devices into responsive stick-style controllers, so you can finally play Asteroids, Space Invaders, Galaga, Defender — or any game you’ve ever wished worked with your trackball — using your real Atari hardware. The cursor automatically returns to neutral when the ball or wheel stops moving, exactly like an analog stick would.
• Six speed levels — Off, Very Slow, Slow, Medium, Fast, Very Fast — let you dial in the perfect feel for each game. Twitchy shooters? Crank it to Very Fast. Slow strategy games? Very Slow lets your cursor coast smoothly back.
• Per-port and per-device — set independently for each port and applies to:
  • 2600 Trackball — multiplicative amplification on natural pulse-rate decel (×1.0 to ×4.0). Higher levels pull the cursor back faster while the ball is still rolling.
  • 5200 CX-53 Trackball — any non-zero level enables auto-center; speed timing governed by the trackball’s internal RC integrator.
  • Atari Driving Controller — linear ax/ay decay after the wheel sits idle, with setting-dependent idle gates so brief pauses don’t trigger unwanted decay.
• Smart DPad Override — when your controller is configured as a DPad, Auto Center automatically engages even if you’ve selected Off. No more dpad locked in one direction after you let go of the ball or wheel.
• Mouse mode is unaffected — Auto Center only shapes the gamepad axis. Cursor / mouse output continues to behave like a true trackball regardless of the setting.

Jaw Cruncher Mini-Game (NEW)

• All-new built-in arcade dot-muncher — chase pellets, dodge monsters, scarf power pellets to flip the chase. Built using the same engine as Iron Dome and Brick Bash, runs entirely on the device with no host or game cart needed.
• Full monster AI — four monsters with classic chase / scatter / frightened modes, monster-home dot counters, level-based scatter/chase phases, frightened mode that slows the monsters and flips them blue. Eat them in sequence for the classic 200/400/800/1600 point cascade.
• Bonus fruit appears at standard dot thresholds with rising point values per level.
• Plays great with most controllers — Atari joystick, trackball, keypad, or your device’s built-in 5-way hat. Pair it with the new Auto Center mode for a fresh take on the classic with your trackball.
• High Score persistence + leaderboard — your top score is saved across power cycles and synced to the iCodeHub community leaderboard alongside Iron Dome and Brick Bash.
• Special surprise Easter Egg — tap away at your buttons during the game and enjoy.

Display & Performance

• New graphics engine — significantly faster screen rendering, smoother animations and display updates.
• Game Engine v2 — improved performance and visuals for built-in mini-games.

Analog & Input Processing
