Nintendo Switch Sports: Voidjoy GA-10 Review—Back Buttons Work, Triggers Don’t

The Voidjoy GA-10 Elite Extender is a badly targeted upgrade for Nintendo Switch Sports. Its $39.99 USD asking price buys meaningful rear controls and useful automation, yet the feature that could have changed how some Switch games feel — analogue triggers — does not function in supported Switch games.

That does not make the GA-10 useless. It makes it specific. Owners of the original Nintendo Switch Pro Controller who want extra buttons, turbo, macros, and battery capacity get real additions. Anyone buying it for variable throttle or brake control on Switch is paying for hardware their games cannot properly use.

• The GA-10 adds two remappable rear buttons, P1 and P2, plus detachable extended trigger paddles.
• KeyLinker handles remapping, trigger calibration, turbo settings, and macros of up to 42 steps.
• An integrated 1,800 mAh battery can charge the Switch Pro Controller while playing.
• The attachment adds 68 g and places its rear buttons far enough inward to make the grip awkward for shorter fingers.
• Its 1280-step analogue trigger hardware works on PC in X-input mode, but not in supported Switch games.

The rear buttons are the actual upgrade

P1 and P2 are the GA-10’s best reason to exist. Each rear button can duplicate an existing Switch Pro Controller input, which lets players move frequently used commands away from the face buttons without giving up control of the sticks. That is a practical improvement for games where a thumb would otherwise need to leave a stick at the wrong moment.

Turbo and 42-step macros strengthen that case. KeyLinker gives the extender a layer of input control the standard controller lacks: repeated presses can be automated, a sequence can be assigned to a macro, and button assignments can be moved around the controller. These are convenience tools, not magic performance upgrades, but they are functional features with clear uses.

Ergonomics pull against the pitch. The buttons sit inward enough that shorter fingers may have to reposition their grip to reach them, and the attachment adds 68 g to the controller. The hardware stays secure, but the original Switch Pro Controller is no longer the clean, uncomplicated pad that made the base controller appealing in the first place.

The analogue-trigger promise collapses on Switch

This is the compatibility failure that defines the GA-10. Its trigger hardware uses 1280-step sampling and responds as analogue hardware should. On PC in X-input mode, that capability works. Supported Switch games, however, do not receive that analogue trigger functionality.

The reason is simple: the original Switch Pro Controller presents ZL and ZR as digital inputs. A Switch game receives pressed or not pressed, rather than a graduated range of trigger pressure. The GA-10 can add analogue-capable hardware to the controller, but it cannot create an analogue trigger channel in the Switch game input system.

For a racing-focused Switch player, that kills the accessory’s most attractive promise. The detachable paddles can still serve as digital inputs, but they cannot produce the variable acceleration or braking that makes analogue triggers valuable. Rear buttons, turbo, macros, and charging remain; precise trigger control does not.

Nintendo Switch Sports gains very little

Nintendo Switch Sports is a particularly poor fit for this extender because its core identity is built around Joy-Con motion controls. The GA-10 adds no motion functionality, does not replace Joy-Cons, and does not improve the motion-focused side of the game.

A conventional-controller setup can still make the P1 and P2 buttons, turbo, or extra battery useful where supported, but that is a narrow benefit. Nintendo Switch Sports does not turn into a stronger experience because the Switch Pro Controller has two extra rear inputs. The GA-10’s most meaningful features are pointed at controller-heavy games with denser button demands, not motion-led sports play.

Who should buy the GA-10

• Buy it if you own the original Switch Pro Controller and specifically want two remappable rear buttons, turbo, macros, or a battery that can charge the controller during play.
• Buy it with PC use in mind if analogue trigger support in X-input mode matters to you.
• Skip it if analogue triggers for Switch racing games are the main attraction.
• Skip it for Nintendo Switch Sports if you expect better motion controls or a replacement for Joy-Con functionality.
• Skip it if you prefer the original controller’s compact feel, have shorter fingers, or own a Switch 2 Pro Controller rather than the original Switch Pro Controller.

Bottom line

I score the Voidjoy GA-10 Elite Extender a 6/10. Its back buttons, turbo, macros, and charging battery make it a competent niche attachment for the original Switch Pro Controller, but the added weight and awkward rear reach already limit its comfort. More importantly, the analogue trigger feature fails where Switch buyers need it most: in supported Switch games. For Nintendo Switch Sports, it is an expensive detour from the Joy-Con controls the game actually uses.
