This device can turn your smartphone into a Game Boy
15 Feb 2026

GameSir has announced a new controller, the Pocket Taco, designed to turn smartphones, including iPhones, into handheld consoles.

The $35 device is an affordable and simple solution for playing retro games without needing thumbsticks.

Unlike other controllers such as Abxylute M4 or Backbone Pro that use magnets or split gamepad designs, the Pocket Taco employs a hinged mechanism that securely attaches to the bottom half of your smartphone.

User-friendly features

The Pocket Taco comes with soft silicone pads on both sides, ensuring a secure grip without damaging your phone.

While it may not be as ergonomic as standalone controllers, the Pocket Taco is still comfortable to use.

Its hinge can attach to smartphones even when they're in bulky cases and can accommodate phones wider than the controller itself.

It only hinges outward about 45 degrees
Design drawbacks

The front panel of the Pocket Taco only hinges outward about 45 degrees, blocking the lower part of your smartphone's screen.

This can be a bit inconvenient as you may have to remove the controller completely to switch apps or unlock your phone.

However, it does come with a passthrough hole at the bottom for plugging in a power cable if your device's charging port is centered.

The Pocket Taco has its own rechargeable battery
Wireless operation

The Pocket Taco connects to your device via Bluetooth and has its own 600mAh rechargeable battery. This means it won't drain your phone's battery while playing games.

The controller powers on automatically when attached to a phone but can also be manually powered on for use as a standalone wireless gamepad.

Its controls are similar to those of the original Game Boy, making it ideal for retro gaming enthusiasts.

It works well with various emulator apps on iOS
Gaming experience

The Pocket Taco works well with Game Boy, Super Nintendo, and GBA games played through Delta emulator and RetroArch on iOS.

However, it should be noted that the controller can only be used in a vertical orientation.

Despite its few limitations, the Pocket Taco has excellent controls, solid ergonomics, reliable Bluetooth connectivity, nearly universal smartphone compatibility, and the option to use it as a standalone wireless gamepad.
