Release notes
Trackball H2 4.00 — November 6, 2026
iCode Arcade Trackball Ultimate USB – Version 4.0 H2
New: a redesigned color display, SNAP for gamepad games, and wake on any button
New Display (NEW)
- Redesigned play screen. A live trackball view, the active preset and its name, mode, sensitivity and acceleration gauges, axis, every button press, and the USB emulation mode.
- See your changes. When a shortcut changes a setting, that part of the screen blinks yellow for two seconds. Rapid fire and the large-button swap show a short message instead.
- Display On / Off. The display settings are now just On and Off; Off draws nothing while you play.
- System Info screen. Settings Menu > System Info shows the model, firmware version and more. The start-up info screen is gone, so the Trackball is ready to play sooner.
SNAP (NEW)
- Acceleration 9 becomes SNAP in Gamepad and Mouse+Pad modes. Each gamepad axis works like a digital stick with three positions — full left, center and full right.
- How it works. Roll 15% of the range to snap to an edge, and the same distance back to return to center. Rolling further toward an edge you are already at changes nothing, so the way back is always the same short distance.
- Good for games that only need left / center / right, and for emulators such as Stella that ignore small movements when you map controls. Turn on GP Recenter to return to center by itself when you stop.
- Mouse is not affected. In Mouse mode the top step stays 9, with normal acceleration.
Shortcuts
- Hold a button and tap Black — shortcuts now work in either press order.
- Using a shortcut never opens the Settings Menu. Tap Black on its own to open it.
Power Off and Wake
- Hold Black for 5 seconds to turn the Trackball off.
- Any button wakes it — not just Black.
iCodeHub
- iCodeHub links on the device and in the manual now point to hub.icode.com.
Good to Know
- Settings and presets may be reset by this update — save them to your iCodeHub Vault before updating and reload them afterward.
